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.

grows about 10 m in
height.
It is part of a species
comples.
8. Ginkgo biloba
Common name:
Maidenhair tree

11. Selaginella apoda
This lycophyte is a

commonly known as
meadow-spike moss.
It is found primarily in
damp soils and it is

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

conifer group once
known only from
