CorDIA APICULATA (Hollick) Berry 
Populus apiculata Hollick, Trans. N. Y. Acad. Sci. 12: 4. pl. 3. f. 2. 
1892. 
Cordia ietiaiats Berry, Md. Geol. Surv. _Upper Cretaceous, 897. 
pl. 90. f. 6. 1916. 
Leaves variable in size and shape, ovate to orbicular in general 
outline, 5-10 cm. in length by 3~7 cm. in maximum width, which 
is at or below the middle. Apex usually somewhat abruptly 
produced into an acuminate tip. Base cuneate and slightly 
decurrent to rounded or almost truncate. Margins entire, some- 
times slightly repand. Petiole of medium length, stout. Midrib 
mediumly stout, often flexuous. Secondaries five or six pairs, sub- 
opposite below, alternate above, slender, branching from the mid- 
rib at angles of from forty-five to fifty degrees and arching upward, 
camptodrome. Tertiaries camptodrome in the marginal region, 
percurrent internally. 
This species in all its characters suggests most strongly the 
existing Cordia sebestena Linné which ranges from the Florida 
Keys to New Guinea. It also suggests Cordia tremula Griesbach 
of the West Indies, and there is a general generic likeness to various 
other existing species of this genus. Cordia leaves are variable 
and tend to have more or less toothed margins as is sometimes the — 
case in Cordia sebestena, but they are in general entire or slightly 
repand, and like the fossil somewhat variable. Cordia is certainly 
represented in the Lower Eocene flora of the Gulf region by forms 
that may be descendants of this Upper Cretaceous species. The 
present form has been recorded from New Jersey, Staten Island, 
Long Island, and Delaware, and is not rare in the lower beds of 
the Tuscaloosa formation in the Alabama region. 
Represented by a single specimen in the present collection 
from the upper member of the Bingen sand.
