NOTES FROM THE EDITOR
As the century comes to a close we complete volume 5 of theJournal. Many changes have taken place over the past five years as
well as four North American Native Orchid Conferences. We have
had our problems with printing, color and mailing but I trust those are
now behind everything and us is reasonably on track. The year 2000promises to be an exciting and reward year in many fields and I am
sure the orchids will be one of them. New species are still being
discovered in North America and many old and familiar species re-
examined and, in some cases, re-addressed with new (or old) names.
November 1999 brought us the sad news of the sudden deathof Bobby Toler, one of the first members of the Alliance. His friend,
and often orchid-hunting companion, Stan Bentley has written a
tribute to Bobby in this issue. I would like to dedicate this issue to
Bobby's memory.
Plans are well underway for the 5th
North American Native
Orchid Conference to be held from July 16-20, 2000 in the
spectacular Olympic Peninsula in the state of Washington. If you plan
on attending please do not delay in sending in your registration.
One of the major features of the Journal for 2000 will be the
4-part series assembled by Anne and Ken Wagner on the Rare,
Threatened and Endangered Orchids of North America (north of
Mexico). This will be the first time all of this information will have
8/8/2019 December 1999 North American Native Orchid Journal
5/77
been brought together for a single periodical.
The Journal is still looking for more articles on local orchid
'hot spots' and treatments of specific species or genera. Please
continue to submit your articles. Several new and exciting things are
happening with the orchids here in Florida with my research for theFlorida Native Orchid Project and those results will continue to be
published in theJournal.

RARE WHITE CALYPSO ORCHID INCLEARCUT COUNTRY:
a personal journey of discovery spiritualityand hope
Gregory E. Brandenburg
The boreal forest of north-central Alberta, thatcollectively I call home, has been a gradual ecosystematic
discovery and appreciation. It's stately spruce, pine andmixed hardwoods blend with marshes, fens, andabundant springs creating a biodiversity that has beenunequaled in my travels. The endearment towards theOrchid family in this northern boreal forest borders onobsessive, on behalf of botanists I have guided throughthese mossy pathways for the past twenty years. Hereflowering orchids span the seasons of the snow freemonths. Eastern fairy-slipper, Calypso bulbosa var.

Within this phenological framing I haveencountered within a twenty-km radius of area that Iregularly explore for medicinal plants, more than twentyspecies of orchids. These include several species ofcoralroots, Corallorhiza, lady's-slippers, Cypripedium, reinorchids, Platanthera, twayblades, Listera, adder's-mouths,
Malaxis, and orchis, Amerorchis, throughout myperegrination over these years.
One of the finest and most memorable sights I'vehad the honour to meet was Calypso bulbosavar. americanaforma albiflora. This colony of white calypso orchids,
within a nation of its more typical pink counter-parts.Distinct, and to a trained eye, outstanding!
The setting of this white calypso colony occursnear a scenic boreal marl spring known as "Granny' sSpring". (Granny Belcourt used to take her water fromthis source, and lived to be 104.)
The special bog adder's-mouth,Malaxis paludosagrows here, as the setting is right. Just the gentle soundsof water flowing into the marl pools. To begin this storyI'll have to introduce you to Tash (Natasha), the
daughter of my friends from the closest village in thearea, Marlboro (Alberta). Tash was about eight years oldin 1991 when from time to time she would accompanyme on excursions or adventures into the forest. Herreceptive eyes and retentive memory added to an
8/8/2019 December 1999 North American Native Orchid Journal

305
abundance of curiosity made her a perfect wanderingcompanion.
During the early months of 1995 Tash haddeveloped a lump under her arm, and it kept growing. It
was now towards the end of May (May 21) - a mostmemorable day - the worst day of my life. On this day
we received word that the lump was diagnosedmalignant. Cancer. A day of tears, anguish, hopelessness,finally turned into hopefulness.
It was a fashioning of a stumbling block into abuilding block. And so a promise was now made to
myself (God keeps his promise. God lives inside you.)For everything there is a reason - awareness gave theanswer. This specific area has been termed by indigenouspeople since antiquity as "Medicine Lodge" It was insearch for a botanical remedy of Tashs clash with cancer
which brought me to roam this location.
I now followed a path once affirmed for me inFindhorn, Scotland. I was viewing the landscape as anEthnobotanist, blending in my botanical excursions, the
combinations of knowledge, pharmicudical botany,diagnosis and spirituality. The night before I discoveredthe white calypso colony was spent in preparation. Themorning of May 22 began with a prayer for guidance forher botanical remedy, and a gathering I did go.

The first ethnobotanical plant of the morning andthe furthest afield I had come to gather was a portion ofthe large yellow lady's-slipper root, Cypripedium
parviflorum var. pubescens. The erect seed stalks hadwithstood the winter snows and its capsules waved like aflag.
Sweetgrass was lit, and a prayer of thanks givenwith a gift of tobacco (You must always give before youachieve.) For ethnobotany is both a spiritual and aconservation endeavor. I carefully removed a portion ofthe root, then liberating to the wind seeds from thecrushed portion of the pods. The formula also required
club-moss, Lycopodium clavatum, the last plant to begathered. From thence time will tell, my finish will nowbe Tash's beginning.
This club-moss was growing around mosscovered rotted lodgepole pine and white spruce stumpson the edge of an area that had been selectively logged inthe late 1950's. Through natural regeneration, spruce,pine, and aspen poplar now blended the forest canopy.
The forest floor waved in a carpet of iridescence through
an incredible proliferation of Calypso bulbosa. Thebeholder was truly a happy wanderer, backpack full ofbotanical treasures, soaked, smiling and appreciative. Irecalled the phrase "what the stars are to the heavens,flowers are to the earth."

Within a field of these pinkfairy slippers a smallcluster in contrast waved with an illumination exhibitinga purity, even a spiritualness that affirmed my missionand exemplified hope, clarity, and faith in miracles. They
were white calypsos - eight of them in full bloom. Acolony unlike any I have ever witnessed then and now.
The great environmentalist and wildernessadvocate John Muir had met two white calypso orchidsin the Holland River Swamps of Ontario in 1866. Hisdescription of these became his first published work
when it appeared in the Boston Record Dec.21, 1866.Muir's description had very much paralleled my own
impressions.
As he wrote" I never before saw a plant so full oflife, so perfect, spiritual, it seemed pure enough for thethrone of its creator. I felt as if I was in the presence ofsome superior being who loved me and beckoned me tocome. I sat down beside them and wept for joy. Couldangels in their better land show us a more beautifulplant? How good is our Heavenly Father in granting ussuch friends as these plant-creatures, filling us wherever
we go with pleasure so deep, so pure, so endless."
Later in life John Muir, queried by a news reporterfor the two most significant events in his life replied,

"meeting Ralph Waldo Emerson, and meeting the whitecalypso orchid in a swamp in Ontario".
For myself as I gazed transfixed, the words of Wm. Blake sprang into mind "To see the world in agrain of sand. Heaven in a wild flower. To touch infinityin the palm of your hand. And eternity within the hour."
To care is to share, and in this instance, it alsoreveals the "all to familiar" perils of trust. I shared theuniqueness of these blooming white orchids with twoindividuals I had guided with the hope of achieving theneeded site protection and the plants receiving thenecessary botanical validation.
Surprise! I revisited the colony four days later, tocheck and say farewell. Where the white calypso oncegrew, all that was left was a shallow scoop, a scar in thecontinuity of the moss carpet. Gone!
As I recall that devastating moment somecompassionate thought did arise; a poem from my firstsummer in the forest, I titled the poem Forest Wind:
There is a forest, it lies beneath my feet.It has no path, but the one it seeksEverywhere round is beauty and lifeAll in balance, with a touch of strife.

Three years have now transpired, and onlythrough the grace of God these little treasures are re-appearing on the fringe of where the whole colony oncegrew. The scar is healing and the memories remain.
The spirituality, romance, and literary aspects ofthe white calypsos are further enhanced with theinclusion of the encouraging response forwarded to mein July 1999 by Paul Martin Brown, Editor of the North
American Native Orchid Journal. After my forwarding aseries of detailed photographs to him, he informed methat his initial conclusion is that the colony appeared tohe the very rare white flowered form of the easternfairy slipper,Calypso bulbosavar. americanaforma albiflora
- the result from a change of a single gene within aspecific seed capsule. Although the white flowered formsare often referred to as albinos they are not as they docontain chlorophyll in the leaves. Whenever seed isproduced from the white flowered forms, they typicallyproduce pink flowered plants. This seems to be the firstsizeable colony of this color form ever found. Thegenetic anomaly normally applies to a sing1e individualnever a colony.
The vibrant green leaves of these plants seem tocontrast from the typically yellowish tinge of other whiteflowered calypso anomaly, nitrogen deficient prospects.Only time and analysis will answer these questions.

In closure Id like to thank Dr. Jim Butler,Professor, Dept. of Renewable Resources, University of
Alberta, for being a catalyst in this writing and taking thetime and effort in these most excellent documentalphotographs.
Along with the above and equal appreciation; PaulMartin Brown of theNorth American Native Orchid Journal,
whose expertise removed one self imposed stigma,"Clueless in the orchid patch" Many Thanks. And to
Tash (Natasha R. Belcourt, Granny's great-granddaughter) who is now fifteen and a half, a healthyteenager, above average, athletic student going into grade11, whose charm and beauty can only deciphered by her
moods. All is well that ends well.
Although these white calypsos grow in CLEARCUT COUNTRY, within a forest management area of
WEYERHAEUSER CANADA, sound selective cuttingon behalf of an earlier, small, local, conscientiousforesters had left the forest floor biologically intact,facilitating these plants. Modern clear-cutting, followedby scarification and planting of favoured monoculturesare less favorable to wild orchid colonies like this one.
Paul Martin Brown described this colony as "veryspecial", and encouraged careful monitoring over theyears to follow this unique colony. Brown alsoencouraged in his communication "Immediate

The author remains hopeful that Weyerhaeuser will accept this location as an area of specialmanagement regulations in the interest of environmentalprotection maintaining the natural genetic and biologicaldiversity of the boreal forest ecosystem.

HEXALECTRIS REVOLUTAIN
ARIZONA
Ronald A. Coleman
Hexalectris revoluta was described by Correll in 1941. It
remains a little known and seldom seen species. Luer (1975)
showed it in only two locations: in the state of Nuevo Leon in
Mexico, and the Big Bend area of Texas. This species has now
been identified in southeastern Arizona, which is a significant
western and northern range extension.
Credit for the first discovery of the plant in Arizona goesto Larry Toolin and Frank Reichenbacher, who discovered it in
south central Pima County in 1981. However, they identified the
plant as Hexalectris spicata, which is reasonable given the keys in
local floras. A second discovery, this time by Steve McLaughlin,
8/8/2019 December 1999 North American Native Orchid Journal

Coleman: Hexalectris revoluta

was made in 1986 in the southern part of Pima County. Like

17/77
Coleman: Hexalectris revoluta
314
Toolin and Reichenbacher, McLaughlin identified the
plants as H. spicata. Both of these discoveries are documented with
collections, housed at the herbarium of the University of Arizona.
My experience with these plants dates from 1996 when
McLaughlin took me to his site in southern Pima County. Only
one plant bloomed that year, and it was damaged by insects.However, the next year over one dozen plants bloomed at that
location, fueling up my suspicion that this was not H. spicata, but
rather H. revoluta.
My tentative identity and slides of the plants taken in 1997
were sent to Paul Catling, who is studying the genus Hexalectris
and preparing the treatment for the Flora of North America
series. We discussed the plants several times, and in 1998 Catlingand Engel confirmed my identification of the plants as Hexalectris.
revoluta. The main characteristic that makes H. revoluta easy to
identify is the presentation of its sepals and petals. They are free
and spreading and rolled back along the outer third of their length
more than 360 degrees. Their background color is light tan to pale
rose. The lateral lobes of the lip have distinct purple veining over
a whitish tan to rose tan base. The central lobe of the lip had the
raised ridges characteristic ofHexalectris.
Hexalectris revoluta has been positively identified at three
locations in Arizona, and is probable at a fourth. The first two
sites are those discovered by Toolin and Reichenbacher, and by
McLaughlin. The author found a third site in Pima County, about

ten miles distance from McLaughlin's site. A fourth location in
Cochise County is suspected to harbor the orchid. In 1998 flower
spikes appeared in late May that looked identical to those of H.
revoluta in size and color. However, the spikes all withered before
the buds were mature enough to make a positive identification.
No plants appeared at that site in 1999. Habitat is the same atboth locations. The plants grow in canyon bottoms and on the
sides of canyons at about 5000' elevation. They root in soil and
duff under oaks and mesquite, often in association with Arizona
walnut. Most of the plants are in moderate shade, but some grow
in bright light part of the day,

Fact Sheet:
PINK LADY'S-SLIPPER
Cypripedium acaule
Anne B. Wagner
Pink lady's-slipper, Cypripedium acaule, may be
the best-known native wildflower. Certainly, it is the
largest and most abundant of about thirty-three speciesof native orchids growing in Rhode Island. Unlike other
orchids, the pink lady's-slipper prefers the dry, sandy,
acid soils and dappled shade of pine-oak or mixed
deciduous forests, although it can be found in wetter
areas, too, on hummocks in bogs and swamps.
Companion plants often include blueberries and
huckleberries.
The two oval, basal leaves lie almost flat upon theground, maximizing the surface area available to collect
sunlight filtering through the canopy for photosynthesis.
A leafless 6-15 scape supports the flower whose lower

lipa modified petalforms the familiar pink pouch
that reminds people of a shoe or a slipper, leading to the
common names of ladys-slipper or moccasin
flower. Indeed, the botanical name Cypripedium
derives from Greek meaning Venus slipper. Usuallythe pouch is a shade of pinkpale to rose to
raspberry with a tracery of red veins. White-flowered
forms (forma albiflora) occasionally occur.
Pink lady's-slippers are not rare in Rhode
Island. Hikers may encounter large colonies carpeting
forest floors during bloom time in May. Individual
plants can live as long as one hundred years, but the
plant may flower only 10-20 times during its lifetime.Producing flowers takes energy and a plant may need
several years to accumulate enough resources to expend
on flower production. Making seed requires still greater
energy; a pink lady's-slipper may set seed only 2-5
times in its life.
Native bumblebees pollinate the flowers.
Bumblebees are strong enough to force open the fissure
in the pouch. As they search for nectar along a route thatbrings their large, hairy bodies in contact with the
saddlebag-like globs of pollen (pollinia) which attach
themselves to the bee as it exits the flower and flies to

Wagner: PINK LADY'S-SLIPPER: Cypripedium acaule
319
the next bloom. Unfortunately, the next bloom may not
be a pink lady's-slipper! Bees quickly learn that these
orchids produce no nectar, so they choose other flowers
to visit. This is one reason why so few of these orchids
produce seed.
When a plant does produce seed, however, the
capsule may contain thousands the size and weight of
dust particles. Orchid seeds are so light because they
contain no endosperm, that nutrient portion of a seed
that nourishes the infant plant. Chance plays a role in
successful germination. Wind-borne pink lady's-
slipper seeds must alight on an appropriate surface and
must establish a symbiotic or parasitic connection with asoil fungus (mycorrhiza.) The mycorrhiza provides the
nutrients that enable the seed to germinate and that
sustain the young plants growth. In the laboratory,
plants can be grown without mycorrhizae. In the wild,
newly-germinated Cypripedium acaule plants may require
several years to develop a root system before sending up
their first leaf.
Pink lady's-slipper roots do not grow deep. They remain in the shallow layer of oxygen-rich,
biologically-active humus. Roots are brittle and delicate,
easily damaged. If a root tip, the active growing portion

How can I transplant pink lady's-slipper plants?Never dig up a pink lady's-slipper! Diggingpinklady's-slippers damages roots so badly that plantsmust live on stored nutrients, depleting theirresources. New roots do not grow fast enough tosupport a transplant and eventually, the plant dies.Rhode Island law states that it is illegal to pick ordig a plant from public or private property
without written permission of the landowner.
Can I grow pink lady's-slippers from seeds Icollected in the wild? Few wild pink lady's-slippers produce viable seed. Many flowers arenever pollinated. When a plant does produce seed,the capsule contains thousands and thousands of
minute, dust-like seeds. The seeds lack endosperm,the nutrient component of seeds that supportsgerminating tissues in most plants. Pink lady's-slipper seeds, dispersed by wind, must establish arelationship with a soil fungus that supplies nutrientsto induce the orchid seed to germinate and establishroots. Under laboratory conditions, pink lady's-slipper seeds have been made to germinate, but theaverage gardener cannot. Possibly, if the seeds aredispersed over an area where plants are already
growing, some seed may germinate. Remember,Rhode Island law prohibits picking plant parts
without written permission of the landowner. Leaveseed capsules on the plants.

How can I increase the number of pink lady's-slippers growing in my woods? One suggestion isto increase the chances of seed production by hand-pollinating some of your blooming plants. Get abook from the library on botany or orchid growingand learn to identify the sexual parts of an orchidflower, that differ somewhat from the sexual parts inmost other flowers. Then get down on the groundand study the pink lady's-slipper flowers until youcan identify the parts. Using a toothpick or twig, pickup a glob of pollen from one flower and transfer it tothe underside of the stigma of a different flower.Remember, not all plants flower every year. It maytake several years for a plant to store the energy to
flower and set seed. There used to be lots of pink lady's-slippers inmy woods, but now there arent as many. Why?
What can I do about it? Pink lady's-slippersprefer dappled or light shade. As nearby trees andshrubs mature, they produce heavier shade, deprivingladys-slippers of light for photosynthesis. Cut downor prune shrubs casting heavy shade. Limb up orprune branches from mature trees or cut down oneor two trees to let in more light. Pink lady's-
slippers suffer from competing roots. Weed aroundthe orchid patch, removing aggressive vines, shrubsand grasses. Other factors affecting pink lady's-slipper populations may include: shifts in drainagepatterns; loss of habitat due to development; too

323
much sun because of logging, clearing ordevelopment; prolonged drought or other adverse
weather conditions; illegal digging of plants bypoachers; root damage by deer or human traffic.
Are pink lady's-slippers rare plants? Pink lady's-slippers grow across Canada from Newfoundlandand Nova Scotia west to Manitoba, south into theU.S. to Georgia, west to Alabama, north toMinnesota and are frequent to abundant in dry tomoist, acid, oak-pine or coniferous forests. Stands of
pink lady's-slippers may comprise a few to dozensof plants, but not all plants bloom every year.Populations may decline over the years because ofincreasingly heavy shade from maturing trees or from
competition from aggressive plants or from someother cause. Some populations of ladys-slippers maydisappear because of development. Perhaps, asRhode Islands abandoned fields succeed into forest,new stands ofpink lady's-slippers may appear.

AN ODDS AND ENDS COLUMN
The Slow Empiricist
I have gone over all my previous columns and
have up-dated some of them and have put them
together in one publication as a bonus for those people
who sent in their 2000 subscription orders by
November 15, 1999. The new compendium should be
included in with your December issue if you complied
with the directions.
When I reread and reworked my old columns,they peaked my intent to up-date you about some of
the events that have occurred since the publication of
the some of the particular columns. I titled this column
An Odds and Ends Column so that I could bring you
this new information on some of the things that have
been happening in the world of orchids as I have found
out about them. Things seem to change all the time
and sometimes for the better.
When I wrote about Florida's dancing lady,
Tolumnia bahamensis, I complained about the
seemingly senseless policy dictating the rescuing of
threatened orchids. I have since learned that you can
rescue orchids without all the waiting for the powers
8/8/2019 December 1999 North American Native Orchid Journal
29/77
Empiricist: AN ODDS AND ENDS COLUMN
326
that be to act on your request if the orchid is threatened
with immediate extermination (like from in front of a
bulldozer). This does not give you carte blanch to go
about raping the country-side but it does allow you to
act more quickly to attempt to save the orchids. Now,this is for the state of Florida. You will have to check
your own state's or country's regulations in this matter
before you act to save a threatened orchid or you could
be in trouble. .
A further up-date on the dancing lady will
hearten you. There have been found several colonies
near the other extant sites, which bodes better for the
survival of this species. Also a rescued plant that was
grown as a terrestrial in a greenhouse environment has
survived and flowered exuberantly this spring. This
suggests that the orchid needs to be treated as a
terrestrial like it grows in the wild. Remember, it starts
in the ground and sends long shoots up a convenient
rosemary shrub where it puts out flowering spikes,
which give it the look of an epiphyte. Previous
attempts to grow it on bark saw the plant decline andwhither away.
If you think that my column on foolers was all
inclusive you must think again. As I explore for
orchids, I find there are lots more foolers lurking out
there. As soon as I can amass enough new ones I hope

to spread the word via another column on them. One
that comes to mind is the tiny fern that puts up a leaf
that looks so much like an orchid out of flower that I
have mistaken it for the orchid. Of course finding the
Ophioglossum is also a pleaser so you shouldn't feeltoo bad if you incorrectly identify it as an orchid. The
orchids are much more plentiful than the fern.
This fall when I returned from Maine to Florida,
I was exploring for flowering plants of Habenaria
quinqueseta at a preserve near my home, I kept
confusing the orchids with common sow thistles that
grew all through the same area. My persistence
rewarded me with a nice stand of about seven plants in
full flower as well as many other sites in that area.
There were large patches of rosettes with a few in
flower to some plants that had begun to ripen into fruit
as well as a few individuals in prime condition. .
New taxa are being identified almost
every month. Like the new color form for Sacoila
lanceolata. After the columns appeared about thenew color form,folsomii,several people contacted the
Journal about seeing that color form in the tropics.
Paul Martin Brown found an old botanical print of the
Sacoila this summer while vacationing in Maine, that
was definitely bronzy-orange rather than the common
red color. He checked the publication of this print at

the herbarium at Harvard University in Cambridge,
Massachusetts. The Harvard copies were identical in
color to the print he discovered up in Maine. The
tropical plants belong to Sacoila lanceolata, but the
color form had not been described so forma folsomiistill remains true. The plants will be studied carefully
in the next few years as the article in the March 1999
Journal about them described the processes to be
employed.
Since for most of the readers this is the time of
the winter season when orchids are hard to come by in
the wild. Unless you live in a southern climate or can
take a winter vacation to a warmer place you will be
hard pressed to enjoy fieldwork as one of my winter
columns lamented. As I also pointed out in that
column, this does not mean you are to sit back and
cool your heels waiting for spring to reawaken the
little gems you love to find in nature. You can spend
some time in educational pursuits as I have urged in
several previous columns. One thing that I didn't
emphasize was the availability of good books on thesubject. If you don't have access to a good resource
like a nearby college or university, or you don't have a
good library or bookstore to explore, study the
Journal! Books are being published that are adding to
our knowledge of the orchids to be found in specific

329
parts of the North American continent. You can find
information about them in most issues of the North
American Native Orchid Journal.Paul Martin Brown
usually includes a good review of the current
literature. This includes the name and address of thepublisher and the price so you may order them for you
perusal. Or, you can urge your library or local orchid
society to buy one for all to enjoy. Or, you could
donate your copy to those institutions for others to
enjoy.
I will close with the admonition that soon the
winter season will be over and you should be using
this time to enrich your knowledge with study. Lots of
my columns harped on this theme so if you have
subscribed early you will have the entire set to refresh
your memory on what can be accomplished. It is still
imperative to continue to grow in understanding and
knowledge about these often, tiny wonders of the plant
kingdom. Now is a good time to get started. Spring is
coming as surely as tax time for all the people who
live in the United States of America. I would muchrather spend time learning something new about
orchids then figuring out my income tax. Wouldn't you
find the study of orchids a similarly pleasant pastime?

NATIVE ORCHIDS OF THE NEW
JERSEY PINE BARRENS
Christine M. Schairer
New Jersey, one of the most densely populatedstates in the Northeast, has a land area of only 7,509
square miles. Many people think that New Jersey is just
an overcrowded resort state, particularly the southern
half of the state. Besides casinos and miles of coastline,
South Jersey is also home to many historic sites like
Batsto and Atsion, and to some of the most spectacular
plant species known to mankind, including a surprisingly
large number of native orchids. Most of which can be
found in a 2,250 square mile stretch of land known as
the Pine Barrens.

The Pine Barrens represents a unique ecological
niche. The Barrens are home to the Pine Barrens
treefrog, Hyla andersoni, the miniature curly-grass fern,
Schizaea pusilla, as well as to 28 native orchids. Its
distinctive flora, wilderness, and complete contrast withurban surroundings make the Pine Barrens a precious
resource. Within the pinelands there are cedar bogs,
swamps, cranberry bogs, blueberry fields, flowing
streams, and tidal rivers. The soil in the Pine Barrens
comprises an intrinsic mosaic of very acidic, sandy
uplands with very few nutrients, and little water-
retention capability-perfect habitat for our native
orchids.
Like many people, I also did not know that the
Pine Barrens was home to many unique forms of
wildlife. In Spring 1990, I came across my first native
orchid, Cypripedium acaule, commonly known as the pink
ladys-slipper, or pink-moccasin flower, while planting
blueberry bushes on a local farm. In August of the same
year along a roadside in Mullica Township, I wasinformed of a colony of plants that might be orchids. In
fact, this colony was Platanthera blephariglottis, also known
as white fringed orchid. My limited knowledge that
there may be more native orchids began to improve. It
was not until 1994, as a sophomore in college, when I
was given a list of the Pine Barren orchids that I became
8/8/2019 December 1999 North American Native Orchid Journal
44/77
Schairer: NEW JERSEY PINE BARRENS
341
determined to find out more about them. After
gathering information on the different types of
environments that native orchids will survive in, I began
my extensive search to find all 28 orchids on the list.
Our native orchids grow in many different types
of environment. Cypripedium acaule grows best in the
humus deciduous woods. I found C. acauleand its white
flowered form, C. acaule forma albiflorum, respectively
growing in blueberry fields, sides of roads, and in pine
forests. One particular area is Batsto where I can usually
find over 200 C. acaule blooming, as well as C. acauleforma albiflorum. I first spotted this particular plant on
May 15, 1995, the day before my 21st birthday when I
almost accidentally stepped on it. Arethusa bulbosa,
dragons-mouth,Calopogon tuberosus, grass-pink,Pogonia
ophioglossoides, rose pogonia, Platanthera (Habenaria)
blephariglottis, white fringed orchid, and Platanthera
(Habenaria) cristata, crested yellow orchid, all grow in
boggy conditions from bogs to ditches. Rose pogonia
and white fringed orchid have been found to existamong roadside ditches.
Native orchids are terrestrial, that is they grow in
the ground. Terrestrial orchids have a sympodial
8/8/2019 December 1999 North American Native Orchid Journal
45/77
Schairer: NEW JERSEY PINE BARRENS
342
vegetative growth, where the growth of the main axis
ceases at the end of a season and resumes the next year
by the development of a different axis. Depending on
the species, the leaves may or may not be present at time
of flowering or may appear separately at a differentseason, such as Tipularia discolor, the cranefly orchid.
Many of the native orchids have prominent corms or
tubers, such as Arethusa bulbosaand Calopogon tuberosus.
According to Carlyle A. Luer, author ofThe Native
Orchids of the United States and Canada, excluding Florida,
terrestrial species without leaves presumably exist
without chlorophyll. In fact, they have become
essentially saprophytic, taking their nourishment from
decaying matter in the soil in conjunction with a
mycorrhizal fungus. This fungus is needed for the
survival of our native orchids. This is why when one
digs up a native orchid, it will not survive for more than
a few years as in the case of the pink ladys-slipper.
Native orchids will not survive in an environment
different from the one they are used to.
The destruction of our natural habitats, as a result
of trampling, mowing, fires, and residential build-up
could destroy our native orchids. For example,
Platanthera nivea, the snowy orchis, once thrived in the
8/8/2019 December 1999 North American Native Orchid Journal
46/77
Schairer: NEW JERSEY PINE BARRENS
343
Bennett Bogs in Cape May County1. However, due to
development this species has not been seen there since
the late 1980s. Since native orchids rely on a special
fungi, mycorrhiza, orchids can not be transplanted from
one environment to another. Due to their beauty, manypeople think that no one will notice if a native orchid is
dug up or picked. In fact, orchid lovers and botanists do
notice. I did come across a corner where Platanthera
blephariglottis and Spiranthes lacera var. gracilis, slender
ladies'-tresses, were growing. The next day when I
went with my father to take pictures, all that was left
were two small holes where two tall Platanthera plants
once grew. We should cherish our native treasures, and
leave the plants and flowers for others to see. The only
true way to reproduce our native orchids is by spreading
the seeds from a seedpod onto a special formula, known
as agar. Once the seed germinates and the plants are
large enough to come out of the flask, they can be
planted back out in the environment. By doing this type
of culture, we know we can try to save some species
from extinction.

ORCHIDS IN BIG ROCK PARK,
SOUTHERN IOWA
Stephen RJohnson, Ph.D.
Big Rock Park, a name denoting an obvious focusing
point for visitors- a large glacial remnant, is a natural area in the
town of Pella, Iowa. Many people probably know Pella as the
home of Pella Windows, but as I discovered, its also home to at
least four species of orchids.
Big Rock Park is an 83-acre bottomland hardwood
forest with a dense canopy of silver maple (Acer saccharinum),
basswood (Tilia americana) and hackberry (Celtis occidentalis).
But floristic evidence indicates that Big Rock Park was once
more open. For example older trees in the park are either burr
oak (Quercus macrocarpa) or honey locust (Gleditsia
tricanthos). There are also several herbaceous plants that
usually inhabit savanna or prairie such as prairie fawn illy
(Erythronium mesochoreum), brown-eyed susan (Rudbeckia
triloba) and wild geranium (Geranium maculatum).
I first became acquainted with Big Rock in the fall of
1997. By the spring of 1998, I was familiar with both the man-

made and deer-forged trails. In early April 1998, I was on a deer
trail and saw the emerging leaves of showy orchis, Galearis
spectabilis. I visited these plants until the emerging foliage of
surrounding herbs and shrubs obscured the orchids' position
completely. But on a man-made trail, farther south in the park, I
found five showy orchis plants with developing flower spikes. I
visited these orchids every day to see their development. When
these known plants began to open their flowers, I walked all of
the man-made trails and discovered four other clumps of showy
orchis in bloom. All of these clumps were within one foot of
the trail.
I never saw any pollination ofshowy orchis but by mid
summer at least one plant from each clump had swollen fruits.
While searching in May for showy orchis on the man-
made trails, I came upon two plants of lily-leaved twayblade
orchid (Liparis liliifolia). These two plants were within four
inches of the trail edge. I monitored them all summer and sawthat they set no fruit. I saw no important insect activity around
the twayblades. In fact the only insect visitor I saw was a tiny
brown ant visiting the flowers. But later in the fall, I saw that
some larger animal had visited them. One twayblade was
flattened steamroller style while most of the trails were

decorated with red, yellow and green paintballs.
The remainder of that 1998 spring revealed no more
orchids. But I was hopeful and persistent. In the first week of
September I was again rewarded with two additional orchids.
The third orchid was autumn coralroot (Corallorhiza
odontorhiza). In early September this orchid grew in profusion
along a trail in the western corner of the park and within site of
the big rock. They grew even in the trails and the park
maintenance staff mowed a few. These mid-September
"flowering" plants were cleistogamous. By the time that these
cleistogamous corral root orchids withered in early October, I
saw a single plant of an open flowered autumn coral root ( var.
pringlez) on a trail a few yards north of the cleistogamous
plants. I saw its vividly spotted pink lip in the corner of my eye.
But I found no other open flowered autumn coralroot orchids in
the area. Phil I

Iowa (Roosa and Eilers, 1994). Spiranthes ovalis is also rare in
Big Rock Park. I found only three plants, only two of which
produced flowers. These plants also developed fruits, but the
fruiting stalks of both plants were cut before the fruits matured.
These three plants were growing on the edge of the trail and
behind them grew vigorous specimens of the invasive Amur
honeysuckle (Lonicera maackii).
The spring of 1999 was wet in southern Iowa and new
growth emerged more quickly and luxuriously than it did in the
previous year. Most of the showy orchis plants that I had found
in 1998, I couldn't find again in 1999. But I did find a
previously non-flowering clump of showy orchis along a trail in
the extreme southwestern part of the park. This comer of the
park has only a thin line of trees next to developing
urbanization. These were also the largest plats of showy orchis
I'd seen in the park. One was over a foot tall with 12 flowers.
They were also growing in the shade of a monstrous new house.
That spring brought bad news to another orchid in the
park. While my friend Mary and I were walking the trail where
the twayblades grew, she saw something that she said looked
like a garlic clove laying on top of the ground. I looked more
closely and found both twayblade corms lying exposed. A

bulldozing mole had apparently unearthed them. I replanted
both corms in their previously held sites but found them lolling
in sunshine two days later. So I moved them down hill about
three feet below their original sites and rereplanted them. I
visited them throughout the spring and by mid May, I saw them
rise from what I certainly thought was death. In fact the plants
looked more vigorous than they had the year before. Still they
set no seed. But they do have another chance.
Despite skirmishing paintball warriors,
encroachment by alien invasive plants and encirclement by
sterile mown lawns, with adequate maintenance, Big Rock
Parks may take its four orchids into the indefinite future. For
any wildflower enthusiast there is much more to Big Rock Park
than the big rock.

IN LOVING REMEMBRANCE OF GEORGEROBERT "BOBBY" TOLER
Roanoke, Virginia
Bobby was an expert "orchid hunter." His
expertise lay not so much in knowledge gained from a
book but from going into the field and experiencing
the plants. He approached the orchids, indeed life, with
an effervescent, childlike enthusiasm. He held a
reverent appreciation for native plants and a completerespect for all people. In the field, while his friends
stood trying to analyze the orchids and impress one
another in a superficial contest of "one-upsmanship"
about our orchid knowledge, Bobby often turned to
more important things. He would quietly assume his
place beside the plant and, with his wonderful
proficiency, unfailingly proceed to record the plant on
film in a way that impressed everyone fortunate
enough to view his photography.
Bobby's contributions to the Blue Ridge
Wildflower Society and the annual Roanoke
Wildflower Pilgrimage are measureless and
responsible in no small part for their success.
Bobby hunted orchids from Newfoundland to

Bentley: IN REMEMBRANCE OF BOBBYTOLER
356
Alaska, from the Green Swamp of coastal North
Carolina to California, and from the Great Smoky
Mountains to the Bruce Peninsula of Canada. But what
Bobby enjoyed the most was meeting new people and
being with family and friends. His humanity was
uncomplicated and genuine with an abundance of
freely given kindness toward everyone. The phrase,
"He never met a stranger," was epitomized in the
personality of Bobby Toler. His infectious and
perpetual smile was a delight for all of us.
Before their retirement, Bobby and his wife
Frieda operated their own very successful lithography
business. He was a Christian man who had a direction
in life and a serenity that few come to know. From theyoung children in the Sunday School class whom he
taught to his adult acquaintances for whom he set such
a splendid human example, Bobby will be sorely
missed. Surviving are Frieda, a son Wayne and
daughter-in-law Abbe, and a special grandson Paul, all
of Roanoke.
Suddenly, I have lost a best friend. But I shall
never be without the memories of hunting orchids withhim and the absolute joy that Bobby brought to my
life. He has now surely gone on to where it is orchid
season all year long, where there is no end to the
chocolate milk, ice cream and strawberries, and Pepsi
Cola. Those of us who were personally acquainted
with Bobby know that we were blessed with his
presence in our lives. He was the best and someday,

phrases. Two simple words will suffice:Bobby Toler.

Notes on the specimens:
All of the specimens cited were previously identified
and/or annotated as either Spiranthes vernalisor S. praecox.
The Beckner collection from Madison County is
especially interesting as it has eight plants on it with two
of them clearly S. xaustralis and the others S. praecox.
Although many of the specimens examined indicate large
numbers of flowering plants present, in reality only a few
would probably byS. xaustralis.
Although both parents are abundant species in the
southeastern United States and frequently occupy the
same habitat, the detection of hybrids has been
surprisingly infrequent. In most locales in Florida
Spiranthes vernalis precedes Spiranthes praecox in anthesis,
but usually there is a short period of overlap in flowering

dates. Although the flowering habit of S. vernalis is
highly variable even from year to year on the same
individualthe floral morphology is consistent. In S.
vernalis the sepals are divergent, the flowers are creamy- white with the lip usually a darker cream to pale
butterscotch and the flowers as well as the rachis are
covered with dense, articulate pointed hairs. This
distinctive pubescence is evident without the aid of a
lens.
Spiranthes praecox, on the other hand, varies in both
its habit and floral morphology. Typical S. praecox is
usually described as having white flowers, with appressedlateral sepals and distinctive raised green veins on the lip.
While this is the most easily recognized of the several
morphs, in Florida plants are more frequently seen with
the flowers entirely green to pale green and lacking in the
distinctive raised green veins on the lip. The 'green
morphs' are found not only in open areas, i.e. fields,
roadsides, etc., but also in shaded woodlands. A form
with pure white flowers, apparently lacking the raised
green veins, also occurs (forma albolabia Brown &
McCartney). Upon careful examination, these pure
white flowers will reveal the pale lemon-yellow veins on
the lip. This third morph is the least common in Florida.

variable from a slender, nearly secund inflorescence to
the classic single-ranked corkscrew habit to a densely
flowered multiple ranked spike. Cleistogamous flowered
plants have been observed in both species in Florida.Hybrids between Spiranthes vernalis and Spiranthes
praecox have only been observed in the field with the
white-flowered/green veined lip morph ofS. praecox,
although S. vernalis is almost always present with the
other morphs ofS. praecox. Because the position of the
lateral sepals is so diagnostic on both species the hybrids
are very distinct. Plants have been found with S. vernalis
coloration and scattered articulate pointed hairs withappressed sepals or S. praecox-like in coloration with
widely divergent sepals. Usually not more than 1 or 2
individuals of the hybrids have been seen in a given site.
Spiranthes xaustralis may help resolve the
frustration that many orchid enthusiasts have had in the
field when trying to determine of they have found S.
vernalisor S. praecox.

Notes on the specimens examined:
All of the specimens examined were previously
annotated as Spiranthes ovalis, Spiranthes odorata or
Spiranthes cernua, 'small flowered race'.
Paul Catling (DAO) notes on the Garber collection:
"Spiranthes cernua (L.) L.C. Rich. These plants
represent a distinctive southern and restricted
race ofS. cernuawhich possesses some features
of S. ovalis. With lateral sepals 8.0 mm long,
glandular hairs 0.25 mm and a lip that is
relatively thick and papillate beneath (insteadof smooth) they are clearly S. cernua. P. M.
Catling 1982."
I have been unable to find any Spiranthes cernua s.l. in
Florida in either herbaria vouchers or in the field.
The Beckner collection from Sumter County was
originally identified as Spiranthes ovalis and annotated by
D. Ward as follows:
"Called Spiranthes ovalisby J.B. on the basis of
habitat, small flower size, and all-white color,
but suggestive of S. cernuavar. odorata, which
J.B. says grows nearby; in dense inflorescence
pubescence and attenuate bracts exceeding
ovaries. D. B. Ward Aug 1970.

The detection of this hybrid presents a taxon that
behaves precisely as one would like a hybrid to appear.
It is intermediate in virtually all aspects between its two
parents. Spiranthes odorata is a common species of richfloodplains, open grasslands and streamsides throughout
the southeastern United States. It is stoloniferous in
nature and therefore is capable of forming large clumps
and often is found growing in flooded areas with the
flowering stems emerging from the water. Spiranthes
ovalisvar. ovalisis a rare to locally common species found
sparingly throughout the southeastern United States,
usually in rich woods and more rarely in floodplains.
Catling (1983) described Spiranthesovalisvar. erostellata, anautogamous variety that ranges throughout the eastern
United States and southwestern Ontario. This variety is
also somewhat rare and local, but much more
widespread. In only four states did Catling show plants
of both varietiesArkansas, Louisiana, Mississippi and
Florida.
Of the five known historical and extant sites for
Spiranthes ovalisin Florida three are purely var. ovalis, one
exclusively var. erostellata and one, at Itchetucknee
Springs, has both varieties present. Only at Itchetucknee
Springs does Spiranthes ovalis share its habitat with
Spiranthes odorata. For more than a kilometer along the
floodplain of the river extensive stands of Spiranthes

odorata occupy the wetter areas near the river's edge.
Back from the shore, closer to the bluffs that separate
the upland forest from the floodplain, can be found
small colonies ofSpiranthesovalisvar. ovalis, and in two ofthese colonies a few plants of var. erostellata. In the
intermediate zone between the S. ovalisand the S. odorata
occur scattered plants of what at first appear to be small-
flowered S. odorata. In fact, the specimen chosen for the
holotype has been annotated as "small-flowered S.
cernua." Although in the past Spiranthesodoratahas been
considered as a variety ofS. cernua, I have been unable to
find any herbarium specimens or extant sites for
Spiranthes cernua in Florida (Brown 1999). Theseintermediate plants are exactly that they are
intermediate in habit, habitat and morphology.
Measurements of ten plants of each taxon reveal that the
hybrids fall exactly between both parents. They are very
easy to identify in the field as they are larger flowered
than S. ovalis but smaller in all aspects than S. odorata.
Leaf shape on both species is similar, but the distinctive
stoloniferous aspect ofS. odoratais lacking in S. ovalis. InS. xitchetuckneensis plants are often clump-forming and
exhibit very short stallions or may occur as individuals.
The plants ofS. xitchetuckneensis are never as tall as S.
odorata and never as slender as S. ovalis. The floral
arrangement is variable from the distinctive three-
ranking of S. ovalis to a densely flowered spike of S.

ovalis, 3 S. ovalisvar. erostellata and 23 S. xitchetuckneensis
were found.Whether this hybrid occurs other than in Florida
remains to be seen. If populations in the Gulf states are
found that contain both parents, especially if var. ovalisis
present, they should be carefully examined for S.
xitchetuckneensis. Catling (1983) states that var. erostellatais
capable of contributing pollen and therefore could be a
potential pollen parent. The described habitat for var.
erostellata is usually old field margins, dry woods anddisturbed areas so the likelihood of S. odorataoccurring
sympatrically is lessened.

Wild Orchids of TexasBy Joe Liggio and Ann Otto LiggioDavid H. Riskind, Scientific AdvisorConnie Herring Hooks Series7 x 9 7/8 in., 240 pp. Color photos, maps $29.95 hardcoverUniversity of Texas Press800-252-3206 www.utexas.edu/utpress ISBN 0-292-74712-8
This long-awaited work on the orchids of Texas hadfinally come forth and in most every way it has satisfied the needfor a detailed work on that state. Texas has five species not foundelsewhere in the United States, and one of the species, Spiranthesparksii, an endemic to Texas. Joe & Ann Orto Liggio'sdescriptions give us full details for all of the 54 species they havedocumented from Texas. Striking full color photos accompanyeach description of all but Spiranthes brevilabris (see below),Hexalectris revoluta, and Deiregyne confusa.The first set of chapters inthe book give a very complete picture of the natural history ofTexas in relation to the geography, orchid habitat and especiallythe response of many orchids to periodic burning.
Each genus and species is covered with a complete naturalhistory of the species and throughout the book sidebars often give
some of the most interesting historical highlight concerningorchid exploration in Texas. County dot maps of Texasaccompany each species description and the full range of thespecies is given.
The only disappointment I found in the book was the lackof keys for identification of the species and an inconsistency in thecitation of common names i.e. Lady's slipper vs. lady's-slipper andlady's-tresses vs. ladies'-tresses. From a taxonomic standpoint a

few points should be noted.Malaxis wendtiioccurs only in Texas inthe United States and not in New Mexico and Arizona as stated(there the similar taxon is M. porphyrea). The correct literaturecitation is given for this range and status but the text does notinclude that information. It is most certain that Schiedeella parasitica
does not occur in the United States, although research is not quitecomplete yet to verify whether that taxon should be addressed asS. fauci-sanguineaor described as a new species. Although no faultof the authors, the photo of Spiranthes brevilabrisvar. brevilabris isthat of Spiranthes eatonii which was described in the March 1999issue of this Journal, too late for inclusion in this book. It wouldadd another species to the orchids of Texas. An excellentbibliography is given in the Literature Cited, although the year givenfor Magrath: Sida 13(3):371 is incorrect. It should read 1989 not1939.
I am confident that all native orchid enthusiasts will want a
copy of this informative and essential volume that presents bothan interesting and detailed narrative of the orchids of Texas. PMB
