This is a handsome, climbing, annual plant, native of 
the East Indies. It, occasionally, is raised from imported 
seed, and in a stove may be cultivated without difficulty : 
but, like all other tropical species of this genus, it cannot 
be made to bear the natural climate of even our finest 
summers. 
Our drawing was made at Mr. Colvill's Nursery. 
Stem climbing, angular, roughish, with deflexed hairs, 
sometimes smooth. Leaflets broad-ovate, approaching to
