Western Peninsula, apparently common, but said to be an escape; common in 

 gardens throughout India and in various tropical countries. 



A glabrous spinous shrub, with straggling evergreen branches and leaves ; spines 

 slender, straight. Leaflets thick and soft, crenulate, coriaceous, almost nerveless, the 

 terminal shortly petioled, |-14 in., ovate with a cuneate base and rounded notched tip ; 

 laterar smaller, more rounded, oblique. i''Zoioers very shortly peduncled, nearly J in. 

 long, white, fragrant. PeJaZs| linear-oblong. Fruit { in. long, fleshy, apiculate, gland- 

 dotted.— Gi-aham (Cat. Bomb. PI. 23) is probably mistaken in supposing that this, 

 which is considered by many to be a Chinese plant, is a native of the Southern Conoan. 

 I am not aware, however, that it has anywhere been found in an indigenous state.
