A large portion of the woodland canopy is made up of typical
Post Oak Savannah trees such as Quercus stellata (Post
Oak)
However, that the woods have much in common with East Texas woods is made
evident by the presence of Liquidambar styraciflua
(Sweet Gum) and Ilex americana (American Holly).
Sweet Gum is easily recognized by its star-shaped leaves and
spiky "gumball" fruits. It has brilliant fall color ranging
from lemon yellow to deep maroon, with multiple colors
appearing on a single tree.
American Holly has spiny leaves that look much like the holly
used at Christmastime. Hollies are dioecious, meaning that
there are separate male and female plants. Only the females
bear the bright red berries.
The canopy is firmly interwoven by a meshwork of Smilax
(Catbriar, Greenbriar) stems. These wiry vines with
their vicious prickles make venturing very far into the woods
a difficult and unpleasant task.
Under the trees the ground is very wet, and standing water is
everywhere. In this shady environment, some interesting
ferns can be found.Pteridium aquilinum (Western Bracken-fern) has
highly-divided, leathery leaves. In this species, the
fertile fronds look just like the sterile ones.
Woodwardia areolata (Chainfern), the fertile fronds
look a bit narrower and thicker than the sterile ones. The
fronds tend to be thinner in texture and a lighter green than
those of Bracken-fern.
Osmunda regalis (Royal Fern) the fertile parts of
the fronds don't look anything like sterile parts. There are only
sterile
fronds on this plant.
The fertile parts are at the end of a frond containing sterile parts
below.
A member of the same genus, Osmunda cinnamomea,
which we have not found at the Flynn bogs, has separate sterile
and fertile fronds.
The fertile parts in both Royal and Cinnamon Fern are almost completely
covered by powdery brown spores.
