1. Plant Organisms

2. Marchantia polymorpha
 Known as the
common
liverwort.
 It is large and
widely
distributed, wi
th species all
over the world.

3. Psilotum nudum
 This is an up-
close view of a
whisk fern, a
primitive
vascular plant
bearing 3-
lobed
sporangia.
Organisms
such as this
were abundant
300 million
years ago.

4. Selaginella lepidophylla
 Called the
Resurrection
Plant, this plant
can turn from a
dried up ball into
a leafy green
plant overnight
by soaking in
water. It is native
to Arizona and
Texas.

5. Equisetum hyemale
 This horsetail is a
primitive vascular
plant.
 It is also called a
scouring rush
because the stems
used to be used to
clean pots and
pans.

6. Lycopodium clavatum
 A club moss
native to
Oregon.
 It has only one
kind of spore, a
condition
termed
homosporous

7. Cycas rumphii
 Commonly known as
Queen Sago.
 It is a small tree that
grows about 10 m in
height.
 It is part of a species
comples.

8. Ginkgo biloba
 Common name:
Maidenhair tree
 This is the only species of
the Phylum Ginkgophyta.
 It is a large tree that has
deciduous fanlike leaves.
 It is popular in cities for it
tolerates pollution well.

9. Gnetum gnemon
 Common name
is often melinjo.
 It is native to
the Pacific
Northwest
 It is a small to
medium sized
tree.

10. Juniperus communis
 This conifer is
known as the
common juniper.
 Its berries are
actually ovule-
producing cones
consisting of fleshy
sporophylls.

11. Selaginella apoda
 This lycophyte is a
spike moss that is
commonly known as
meadow-spike moss.
 It is found primarily in
damp soils and it is
mainly a lowland
plant.
 The plant was
originally described by
Carl Linnaeus himself.

12. Equisetum arvense
 This pterophyte
known as the
common horsetail.
 With jointed
stems, rings of
small leaves at the
joints, and the stem
being the main
photosynthetic
center, this species
is the epitomy of an
arthrophyte.

13. Plagiochila deltoidea
 This is a leafy
liverwort that
lives on wet
ground.
 It can get up to
60 mm long.

14. Anthoceros agrestis
 Commonly called a
field hornwort.
 This species of
Anthocerophyta is
known fro containing
acids like cinnamic
acid 4-hydroxylase.

15. Psilotum nudum
 This is whisk fern of the
phylum pterophyta
commonly called
Skeleton Fork Fern.
 It has no roots.
 It is considered a
primitive plant, possibly
a descendent of the first
vascular plants.

16. Wollemia nobilis
 An evergreen tree
known commonly as
the Wallemi pine. It
is a survivor of a
conifer group once
known only from
fossils.
 It was discovered in
1994 in a national
park in
Sydney, Australia.
 It consists of merely
