396 Berry: MESOZOIC FLORA OF ATLANTIC COASTAL PLAIN 
Arthurs Bluff, but neither of these species is represented in the 
present collection. Both are characteristic forms and so different 
that there is no possibility of confusing them with the species 
just discussed. 
ROSALES 
. PALAEOCASSIA LAURINEA Lesq. 
Palaeocassia laurinea Lesq. Fl. Dakota Group 147. pl. 64. f. 12. 
1892. 
This species was described from the Dakota group of Kansas, 
to which it has been hitherto confined. As interpreted by Les- 
quereux, its describer, the remains represented leaflets of a Cassia- 
like plant, although so far as I know, all have been found detached, 
‘the only basis for considering them leaflets rather than leaves being 
‘their slight inequilateral form. 
A single entire leaf is contained in the collection from Arthurs 
Bluff. It is identical with the type material from Kansas in size, 
outline, and venation, with the exception that it is slightly wider 
(2-5 mm.) with a consequently somewhat fuller and more rounded 
base. It has recently been detected in the lower Tuscaloosa of 
Alabama. 
COLUTEA PRIMORDIALIS Heer 
Colutea primordialis Heer, Fl. Foss. Arct. 6°: 99. pl. 27-f- 7-1 
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. 
The collection from Arthurs Bluff contains a single complete 
and in every way typical leaf of this species.
