130 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Cryptostegia grandiflora. 
An East Indian asclepiadaceous vine; has been introduced into Jamaica. It is 
said to produce rubber of good quality, but the latex is not abundant and collec- 
tion is slow and difficult.

ter, 10 to 12 inches (25 to 80 centimeters). Wood rather hard, ash-colored; specific 
gravity, 0.888; used in building country houses. (Exp, 1857.) (Grosourdy, 2: 
379). Captain Hansard says that it is mostly of small size, the saplings, measur- 
ing about 3 inches (7 centimeters), being used in hut building; specific gravity, 0.84. 
Cucumber. See Cucumis anguria and C, sativus,

A tree fromall parts of the island; height, 35 to 40 fect (11 to 12 meters); diame- 
ter, 12 to 15 inches (80 to 45 centimeters). Wood yellow, rather hard; specific
