Koh Chick, in the jungle (No. 862). 
Area: Malaya — Cultivated in Saharunpore, Hongkong &c. 
Sph. Wallichiana Schauer in DC. Prodr. v.11, p. 629, i. e. S. pen- 
tandra, Wight Ic. Pl. Ind. Or. t. 1475, i. e. Roscoea pentandra, Roxb. Fl. 
Ind. v. 3, p. 54, a Sylhet plant, differs much in the size, shape and texture 
of the leaves, in the calyx-teeth 5 only, subtruncate; and appears speci- 
fically distinct enough from Sphenodesma Jackiana. But there are inter- 
mediate sub-species or varieties, of which Sph. acuminata Wight Ic. PI. 
Ind. Or. t. 1476 is one; and in the Flora of British India, the whole 
series was united in one broad species as had been previously done in 
the Kew Herbarium. At all events, the Koh Chang example is typical’ 
Sphenodesma Jackiana Schauer.
