Spring Flora of Oklahoma 
P"or our next example, we will take the Carolina Anem¬ 
one, which also blooms early in the spring. Now turn 
to the Key to the Families. Clearly, it belongs to Class II, 
Dicotyledons. After reading paragraph I on page v and 
paragraph II on page xiii, we find that it belongs under I, 
since the flower has a perianth of similar segments. Read 
after A on page v, and after B on page xi. It is evident 
from the description given here that it belongs under the 
B. Under this heading there are two general groups, 
“Trees, shrubs, or woody climbers” and “Herbs or herbace¬ 
ous vines.” Since this plant is an herb, it belongs under the 
second heading, “Herbs or herbaceous vines.” The next 
choice is “Flowers partly or completely epigynous” or “Flow¬ 
ers hypogynous.” This flower is hypogynous. The families 
with hypogynous perianths are grouped under two divisions 
and of these the second, with its “Carpels free or only united 
at the base,” corresponds to our specimen. Under this divi¬ 
sion there are two families and our specimen having many 
distinct carpels traces to Family 25 Ranunculaceae, page 
44. Turning to the key to the genera of the Crowfoot 
Family, page 44, it is found that our specimen falls under 
the second main heading, “Carpels one-ovuled, etc.” The 
plant having flowers subtended by involucres, traces to 
the Genus Anemone, page 46. After reading the descrip¬ 
tion of the genus to be sure that no mistakes thus far have 
been made, read the key to the species. Since the “Invol¬ 
ucre is mostly below the middle of the scape,” it is therefore 
Anemone caroliniana Walt. The name was given it by 
Thomas Walter, as indicated by the abbreviation Walt, 
following it. 
u is used to indicate feet, 
is used to indicate inches. 
" is used to indicate lines or twelfths of an inch. 
1 line (1”) is equivalent to approximately 2 milli¬ 
meters.' 
The measurements have been given in feet, inches and 
lines. A ruler divided into twelfths of an inch will be 
found at the bottom of page xvi for the student’s con¬ 
venience.
