186 Berry: MESOZOIC FLORA OF ATLANTIC COASTAL PLAIN . 
missing, probably peltate. Margins entire, more or less undulate. 
Texture coriaceous. Venation coarse. Five or six stout primaries 
diverge at acute angles from the top of the petiole and fork dichot- 
omously about 5-6 cm. above their base at angles of thirty to fifty 
degrees. These branches may again fork dichotomously in a 
distance of 4-6 cm., or may not give off any branches, or the 
branches may be clearly subsidiary in size and run to the apex 
of a subordinate lobe. There are a sparse number of relatively fine 
secondaries, which diverge at angles of about forty-five degrees or 
more and are apparently camptodrome. In each of the large 
specimens a straight vein of secondary size runs directly to the 
base of a single main sinus. It is possible that this vein diverges 
along the margin in a vein which forms a marginal hem, as in the 
sinuses of lobed sassafras leaves, but such a vein can not be made 
out, although at one point there is such a marginal vein connected 
with the main venation by straight transverse tertiaries. Deep 
and narrow but rounded sinuses approach within 3-5 cm. of the 
base and divide the leaf into five or more major lobes; these are 
subdivided by more or less deep sinuses of a similar character into 
inequilateral, ovate lanceolate, obtusely pointed subordinate lobes. 
This remarkable species was described from perfect material 
from the lower Eutaw of western Georgia although the leaves are 
so large that it is usually represented by fragmentary specimens. 
It occurs in the Eutaw and Ripley of western Tennessee, in the 
Ripley of Georgia and in the Black Creek formation of North 
Carolina. Several broken specimens have been collected from the 
upper member of the Bingen sand. 
OccURRENCE: Big Railroad Cut, one mile southwest of Max- 
well Spur, Pike County.
