418 Berry: MESOZOIC FLORA OF ATLANTIC COASTAL PLAIN 
sandstone in 1866 by Professor Heer. It was subsequently de- 
tected in western Greenland by the same author and has been 
found to be abundant in the coastal plain from Marthas Vineyard 
to Texas. It is especially abundant in the upper Raritan at 
South Amboy, New Jersey, and is found in the Maryland Raritan 
at Bull Mountain in Cecil County. 
Diospyros vera sp. nov. 
DESCRIPTION: Calyx small, four-parted, 11.5 mm. in diameter 
from tip to tip of the lobes, which are obtusely pointed and nearly 
orbicular in outline, about 4 mm. or 5 mm. in width, contracted 
proximad and somewhat reflexed, coriaceous, longitudinally veined, 
with inflexed margins, which gives them a spoonlike form. Sinuses 
rather narrow and pointed, extending two thirds of the distance 
to the peduncle. The central disk of the calyx appears flat. 
There is a raised collar at the insertion of the peduncle, the latter 
from its scar appearing to have been relatively slender. (PLATE 
19, FIG. 5.) 
The present species is based upon the single specimen figured, 
which shows the lower, peduncular face of the calyx. It is clearly 
referable to this genus and the calyx was probably accrescent as in 
the modern forms. It is much smaller than in our common Amer- 
ican Diospyros virginiana L., but may be matched in some of the 
still existing species and is almost the exact counterpart of some of 
the calices of Diospyros brachysepala A. Br., figured by Heer from 
the Swiss Tertiary. There can be no question regarding its 
identity and in this respect it is much more conclusive than the 
Calycites diospyriformis described by Newberry from the middle 
Raritan of New Jersey, which has a five-lobed calyx. Its occur- 
rence at the same horizon in which the leaves of Diospyros primaeva 
Heer are so abundant not only suggests that it may have been 
borne by the same tree that furnishes the leaves found all the 
way from western Greenland to Alabama, but also serves in a 
measure to corroborate the identification of these leaves. 
The family Ebenaceae has only five modern genera but these 
include a large number of species, a majority of which are referred 
to the genus Diospyros. The latter has about 180 existing species 
distributed in both hemispheres. They are mostly tropical, a 
few species extending beyond the tropics in eastern North America,
