Stems numerous, very slender, twining, glabrous, the old 

 ones semi-woody, often rough with lenticels ; 1. rather small, 

 compound, Iflts. 5, sessile, oval, tapering at base, obtuse, 

 mucronate, glabrous on both sides but rough with minute 

 asperities above, finely spinous-ciliate on margin, pale 

 beneath, the terminal one the largest i^-if in., petiole about 

 as long as 1., prehensile at base ; fl. large, usually solitary often 

 2 or 3, on swollen ped. about \ in. long, bracts minute, 

 peduncle very short, curved downwards ; sep. barely \ in.,

Throughout the Tropics. 



The large flowers are attractive from their peculiar colour, and the 

 plant is a good deal cultivated. The plant figured in Bot. Mag. t. 4305 as 

 /. pulchella, and said to have been raised in 1845 from seeds sent from 

 Ceylon, appears to be a different species, and not a native of this 

 country.
