Sph. Wallichiana Schauer in DG. Prodr. v. 1 1 , p. 622, 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. PL 

 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.
