Hancea, which I have named in honour of my friend Dr. H. E. Hance, the indefatigable explorer of 
the Flora of Hongkong, is closely allied to Chastocarpus, Thwaites (Hook. Joum. of Bot. and Kew Misc. 
Tol. vi. p. 300. t. 10-4), but differs in its numerous free stamens and echinate capsule, etc. There is as 
yet only one species known, viz. : — 
531. Hancea //oo^mawa. Seem. (Tab. XCVI.) Hongkong (Champion!).
