impressive basket display with 10 mixed Dendrobium species in Spanish moss.

A LETTER FROM HEINRICH BEYRLE IN GERMANY
Dear Roy,
Sadly I read in the last NOSSA Journal of the death of Jack
Warcup.
Enclosed please find a photograph of a recently flowered
hybrid: Calochilus robertsonii x Thelymitra nuda. I made this
cross in 1993, germinated seeds in 1995 and it flowered in
March 1998. As these hybrids do not appear to occur in the wild
and artificial hybrids between Calochilus and Thelymitra are not
previously recorded as flowering, the hybrid is of some
scientific interest!
I expected the flowers to be similar to Calochilus imberbis but
with the colours of green, yellow, blue and red it is much
prettier. I intend to register it at Kew as Calomitra 'Memoria
Jack Warcup'.
(Many people will remember Heinrich when he worked here In
Adelaide at Waite under the guidance of Jack. Eds)

RHIZANTHELLA
The underground orchid has now been reported from Yorke Peninsula which means it has been supposedly seen
over a 500km area of South Australia.
SPRING SHOW
Yes its only a few weeks to our Spring Show at St Peters Town Hall! We will need trading table plants. Please fill
out the volunteer book at the next meeting. We need ticket sellers, PR persons, trading table experts tea makers
and lots of exhibitors!
Television and orchids
On a recent Burkes Backyard the terrestrial Pterostylis concinna was shown.
On September 18th Gardening Australia with Mike Harrison contained a segment on Native Orchids

SPECIAL RAFFLE:
a copy of the much prized 1911 edition of South Australian Orchids, by R.S. Rogers is to be raffled over the next
2 months. Tickets will be on sale at meetings and the Show.
JULY SPEAKERS
We had a fascinating demonstration on deflasking. Firstly Kevin Western showed slides of well developed
terrestrials in flask, plants with large tubers, plants actually flowering in flask, and even discussed the possibility
of a self pollinated species setting seed and that seed germinating in the flask to complete the cycle!
Kev showed how a jet of water is used to wash off the agar.
Les Nesbitt and George Nieuwenhoven completed the show by demonstrating how to deflask both terrestrials and
epiphytes.
AUSTRALIAN DENBROBIUMS No 28 by Sandy Philips
Dockrillia schoenina
This species was named by Lindley in
1846 (as Dendrobium schoeninum)
from plants grown at Kew.
The name honours the 19th Century
botanist and naturalist Schoenin.
Found growing on rocks or trees from
Newcastle north to Mackay. It forms
large tangled clumps which are
suberect or hang downwards depending
on light intensity. Flowers are few and
usually single, although there may be 2
or 3 sometimes. Leaves are pencil-like
or grooved and often develop black
markings. The flowers are white as for
the genus, about 3cm across and with
green or purplish markings.
Relatively common on Sheoaks along
creeks and rivers. Previously also
known as Dendrobium beckleri F.
Muell. This easily grown species is
grown cool in Adelaide on wood or
even outside on fruit trees.

NOTES ON THE COLOUR PLATES in ORCHIDS OF SOUTH AUSTRALIA
(continued)
Plate 87 Corybas fordhamii has to be one of the most difficult orchids to find, (perhaps only exceeded by the
underground orchid). It hides under tussocks of grass in deep bogs and would probably never have been found if
cattle had not eaten out the swamp thickets which hid them. The same cattle will probably cause the extinction of
the species in SA.
Plate 88 Corybas incurvus comes in many forms, from translucent green to cherry red, hispid or not. These dark
coloured specimens were growing in Wirrabara Forest in the Flinders Ranges.
Plate 89 This plant of Corybas unguiculatus was photographed in the Mylor Parklands. Note that the column can
be seen through the transparent flower base.
Plates 90-91 Cryptostylis subulata the moose orchid also photographed at Mylor (in the Adelaide Hills) the
boyhood home of the author. In the 1950's over 100 orchid species could be found within walking distance of the
town.
Plate 92 Cyrtostylis reniformis a real close up of the flower by Paul Reece, this shot clearly shows the rounded
labellum apex typical of this species.
Plate 93 From close-up to whole plant, the flowers of Cyrtostylis robusta may look similar to those of the
previous species but if you look closely at the flowers you can see the pointed tip on the labellum on these much
larger C. robusta flowers
NATIVE ORCHID SURVEY AT UPPER STURT SCHOOL 1996-7 Thelma Bridle
NOSSA conducted a survey of this area in the early 1980's. In 1996 the school requested assistance to update this
information so that it could be included in their application for Heritage Listing of the school grounds.
Different species of orchid can be found in flower here at most times of
the year so we were pleased to be invited to a winter visit in 1997.
This co-incided with a barbecue and working bee in which a bush-care
group were assisting parents and students in removal of exotic
shrubs. Epacris impressa in cerise, pink and white were flowering in
profusion at this time and many fungi were recorded. We were able
to identify orchids for those present and point out some we hadn't seen
before . The visit added 4 species not on the orchid list. As there were a
couple of species we wished to positively identify with flowers I returned
in August but added nothing new. A final visit in December confirmed
Dipodium roseum , the saprophytic hyacinth orchid in flower.
Over a ten year period there were few changes in the orchid populations
although in different years the different weather conditions affected the flowering of most species. Populations of
most species seem viable as seed is set most years and numbers are static or growing. All species have been
identified from flowering plants.
