Pogonatum

Kingdom : Plantae

Phylum : Bryophyta

The Pogonatum mosses grow in tufts on the ground, often with a green felt of thread-like

cells (protonema) at the base. The plants are short and simple, or long and robust; with

branches starting below the leaves at the base of the pedicel, or half-way up to the stem.

The male plants continue to grow from the centre of a terminal rosette of bracts.

The leaves are erect or spreading, the upper-half lance-shaped or strap-shaped; the base

is clasping, with large pale cells; the margins are entire or serrate; the vein is broad, with

numerous lamellae occupying almost the entire width of the leaf-blade, and with their

terminal cells smooth or bearing tiny projections (papillose).

The generic name Pogonatum, from the Greek for; a beard, refers to the veil, which is

hairy and almost covers the spore-case. The spore-cases are cylindrical, but not angular.

They are nearly symmetrical, erect, or turned to one side, with flat lids having a centralpoint. They are borne on erect pedicels.

There are one hundred and fifty-six species known in all, nine in North America.

Marchantia

Kingdom: Plantae

Phylum: Hepatophyta

Marchantia is a genus in the family Marchantiaceae of the order Marchantiales, a

group of liverworts.

These are simple plants without roots or vascular systems. They were once

considered related to mosses and part of division Bryophyta, but more recently

have been assigned their own plant division, Marchantiophyta.

Marchantia thallus shows differentiation into two layers: an upper photosynthetic

or assimilatory region and a lower storage region with a well defined upper

epidermis with air channels (barrel-shaped). It features tiny cup like structures

called gemmae cups, which is used for asexual reproduction.

Kingdom: Plantae

Phylum : Marchantiophyta

Plagiochila is a large, common, and widespread genus of liverworts in order

Jungermanniales.It is a member of the family Plagiochilaceae within that order.

There may be anywhere from 500 to 1300 species, most of them from the tropics;

the exact number is still under revision. The genus also has a wide distribution in

temperate and arctic areas.

Eucheuma

Kingdom : Plantae

Phylum : Rhodophyta

Eucheuma is a group of red seaweeds/seaplants representing the Tribe

Eucheumatoideae, used in the production of Carrageenan, an important product

used in cosmetics, food processing and industrial uses, as well as a food source for

those living in Indonesia and the Philippines. Some of the most significant species

include Betaphycus gelatinae, Eucheuma denticulatum, and several species of thegenus Kappaphycus including K. alvarezii.Since the mid-1970s Kappaphycus and

Eucheuma have been the major source for the expansion of the carrageenan

industry.
