Dr. George Green. (No. 1.) "The specimen received is 
wnite fleshed, mealy, and of fair flavor when cooked. 
The vine is round stemmed, glaucous, and armed on the 
lower parts with short but strong recurved thorns. The 
leaves are opposite, and on the lower parts of the main 
stem are modified into bracts from the axils of which 
arise lateral branches. The variety appears to be dif- 
ferent in quality from the one commonly grown inPorto 
Rico." (R. A. Young.)
