TITE riiOEA HONSKONGENSIS. 39 



tloned in Mr. Hanbury's valuable paper on Cardamoms, I have 

 purposely given a very full diagnosis. 



*Microstylis congesta, Rchb.fil: in WaVp. Ann. Bot. Syst.yi. 206. ( = 

 Dienia congesta, lAndl. ; Benth. Fl. hongl. 352.) " Hue revoeandse 

 sunt omnes Dienia, Lindl., ob solum direetionis columnse, eharacterem 

 baud sufiBcientem, olim separatae. Quaiu bene congruunt hsee genera 

 ex eo patebit, quod ill. Lindley exacte eandem plantam Microstyli^ 

 dem monophyllam et sub Microstylide et "sub Dienia {D. Gmelim) 

 descripsit." — Rchb.fil., I. c. 



35. Thelasis? pygmsea, Lindl. inJourn. Linn. .S'lje. iii. 63. (= Eupro- 

 boscis pygmaea. Griff. ; Wight, lo. t. 1732.) 



Three or four specimena 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 whetheir this was referable either to the Indian 

 species or to the Philippine T. triptera, Echb. 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. 

 Q. Eeichenbach ("Walp. Ann. Bot. Syst. vi. 923) in T. triptera. 



36. Sarcanthus teretifolitis, 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-shapfed 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 ia Pol. Orchid, p. 1) for Imisia teres, Blume — 

 Colonel Champion having found his specimen, which was flower- 

 less, in apparently the same locality. Difi'erent as the two are in 

 floral structure, sterile specimens are very much alike indeed. Of 

 Idiisia 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. PI. 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 aU. 



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 him as 

 Colonel Champion's plant' described as A. Ufaria by Dr. Lindley,
