THE FLORA HONGKONGENSIS. 127 
tioned in Mr. Hanbury’s valuable paper on Cardamoms, I have 
purposely given a very full diagnosis.

boscis pygmea, Griff. ; Wight, Ic. t. 1732.) 
Three or four specimens only, gathered by me at Aberdeen in 
August 1857, but found by no one since, and only known besides 
from Malabar, the Khasia mountains, and Nipal. Prof. Lindley 
did not feel sure whether this was referable either to the Indian 
species or to the Philippine 7. triptera, Rchb. fil. But in one 
specimen I find a fruit or two already split along the sutures ; and 
there is no trace of wings to the ovary, as described by Prof. H. 
G. Reichenbach (Walp. Ann. Bot. Syst. vi. 923) in T. triptera. 
36. Sarcanthus teretifolius, Lindl. Gen. et Sp. Orch. 234. 
On rocks below Victoria Peak; gathered by me in October 
1853. Not found by any other collector, and not known out of 
Southern China. This is undoubtedly Lindley’s plant, readily 
known by the long blunt helmet-shaped spur of its lip, with the 
apex produced into a sharp fleshy process, and by its thickly 
bearded column. But I strongly suspect it is also the one taken 
by Lindley ( Luisia in Fol. Orchid. p. 1) for Lwisia teres, Blume— 
Colonel Champion having found his specimen, which was flower- 
less, in apparently the same locality. Different as the two are in 
floral structure, sterile specimens are very much alikeindeed. Of 
Luisia teres I have seen no Chinese example; but I possess a 
Japanese one from M. Maximowicz labelled as from mossy rocks 
on dry mountains around Nagasaki, where it is very rare. Thun- 
berg's plate of this (Icon. Pl. Jap. dec. i. t. 7), which Blume 
(Mus. Bot. Lugd.-Bat. i. 64) styles * mediocris," is really value- 
less, as it shows no flower at all. 
37. Appendicula. 
I have two species of this genus from Hongkong. One, gathered 
by Mr. J. C. Bowring in March 1859, and given me by bim as 
Colonel Champion's plant described as A. bifaria by Dr. Lindley,
