BERRY: MEsozoIc FLORA OF ATLANTIC COASTAL PLAIN 407 
COLUTEA PRIMORDIALIS Heer 
Colutea primordialis Heer, Fl. Foss. Arct. 62: 99. pl. 27. f. 7-11; 
pl. 43.f.7,8. 1882. 
This well marked little species was described from the Atane 
beds of Greenland. It occurs in strata at least as old as the upper 
Raritan in New Jersey and is present in both the Dakota and 
Magothy floras. It is present in the collections from Grove Point, 
Cecil County, Maryland, where it is associated with Colutea 
obovata Berry. 
Dalbergia severnensis sp. nov. 
DEscrIPTION: Leaves of rather small size, oblanceolate in 
general outline, with a markedly emarginate apex, gently curved 
sides, and narrowly pointed base. Length about5cm. Maximum 
width about 1.5 cm. in the middle part of the leaf. Midrib stout 
below, thin above. Secondaries five or six pairs, branching from 
the midrib at angles of 45 degrees or less, the lower ascending, 
the upper curved, all eventually camptodrome. 
This handsome form, which is clearly distinct from any pre- 
viously described species, is identical in its characters with the 
forms usually referred to Dalbergia. (PLATE 19, FIG. 2.) 
OccURRENCE: Little Round Bay, Severn River, Anne Arundel 
County, Md. 
Ilex severnensis sp. nov. 
DESCRIPTION: Leaves of small size, oblong in general outline, 
with a cuspidate apex and a narrowly rounded base. Length 
about 2 cm. Maximum width about 6.5 mm. Texture coriace- 
ous. Margin entire below; above, with a few irregularly spaced 
salient serrate teeth. Midrib relatively stout. Secondary vena- 
nearly straight, diverging from the midrib at angles of about 90 
degrees, giving the leaf a scalariform appearance, as shown in the 
enlarged figure of this form. (PLATE 109, FIG. I, 
This small species is clearly new and is closely allied to various 
species of J/ex. 
OccuRRENCE: Little Round Bay, Severn River, Anne Arundel
