8mm. in length by about 3 mm. in breadth, with a rounded- 
truncate apex and a somewhat narrowed acute base. Of the venation 
only the midrib is discernable. 
The genus Podogonium is entirely 
() extinct and is referred by Heer and 
others to the Caesalpiniaceae although 
Unger placed it in the Papilionaceae. 
In all there are about a dozen species, 
all Tertiary and ranging in age from 
the basal Eocene to the basal Pliocene 
(Messinian). It is chiefly European 
with but two species recorded from 
America. Five species have been 
found in the Tortonian of Europe.

DALBERGIA CALVERTENSIS sp. nov. 
Family Papilionaceae Q 
Leaflets small, 8mm. long by 4.5 mm. in greatest width, ae 
which is toward the apex, obovate in outline with an emarginate to 
retuse apex and gradually narrowed acute base. Secondaries three 
pairs, opposite, ascending, camptodrome. 
There are upward of eighty species of Dalbergia in the modern 
flora ranging through the tropics of both the old and the new worlds. 
The genus is abundantly represented: during the Mid-Cretaceous by 
five or more species in Greenland and on the North American main- 
land. In Europe it is rather common during the Tertiary, Heer 
describing no less than four species from the Tortonian. ‘There 
are also ten or a dozen species recorded from various European 
Oligocene localities.
