Near H. ca^yitellata WALL, and H. Elmeri MERRILL, but differs from the 

 former in having stalked flowers, and from the latter in having narrower 

 leaves, and much narrower calyx-lobes. The flowers of H. capitcllota are 

 nearly sessile. Our plant appears also to be near H. macrostemon H. et A. 

 which I saw in the Herbarium at Hongkong; but, so far as I can judge from 

 the floral characters of the species given in " HOOK, et ARN. Eot. Beech. Toy. 

 p. 192," they are not at all similar, but very distinct.
