Canavalia, which number about a dozen, of the tropics of both hemis- 

 pheres. In the Lower Eocene of southeastern North America there is an 

 undoubted species of Canavalia very close to the existing Canavalia obtusi- 

 folia (Lamarck) D. C., a common West Indian strand plant.

Description. Leaflets elliptical in outline, 3.2 cm. to 4 cm. in length 

 by 1.5 cm. to 1.7 cm. in greatest breadth, which is about half-way between 

 the apex and the base. Texture subcoriaceous. Apex rather broadly 

 rounded. Base slightly narrowed and decurrent to the point of attach- 

 ment. Lesquereux speaks of a short petiole, but this is lacking in his 

 type figure and in all the specimens examined by the writer. The midrib 

 is not especially wide, but is quite prominent. The secondaries are thin 

 and alternate ; they number about six pairs, and branch from the midrib 

 at angles of 50, or somewhat less, curving upward close to the margins, 

 camptodrome. 



This species was described originally from the Dakota group of Kansas, 

 and subsequently found in the Magothy formation of Maryland and the 

 Tuscaloosa formation of Alabama.
