ON THE GENUS HEDYCHIUM. 19 



the former I liad drawn and engraved many years ago, as men- 

 tioned by that author. They differ not even as varieties I believe. 



8. TL.rjracile ; glahrum, omnibus partibus minutissime glanduloso- 



punctatum, foliis ovato-lanceolatis acuminatis, bracteis binis 



convolutis unifloris tubo parum brevioribus, laciniis limbi 



lobisque labelli iere bipartiti linearibus, stamine valfle 



ponecto. 



H. gracile, Pi.oxh. Corom. Plants, iii. p. 48, t "^ol, fig. infer. 



dextra (folium tantum flosque dissectus). Flor. hid. i. p. \2 (c. 



nota Care\'i). 



H. glaucum, Eosc. Mon. PL n. 3. 



Wild in the Sikkim Himalaya, Hooker and Cathcart ; Kasia, 

 Collectors ; also Zl/rs. Mack and Griffith. 



All the parts of the plant, leaves, bracts, calyx, and corolla, 

 even the filament, are marked with copious minute, globular, 

 brown, and semi-pellucid glandular dots, visible only under the 

 microscope, more particularly the parts of the flower. This 

 punctuation exists in a greater or less degree in most if not all 

 the species. I have before me a lai'ge number of specimens in 

 all stages, particularly those collected by Drs. Hooker and Thom- 

 son ; which, although differing apparently among themselves, I 

 am unable to distinguish even as varieties. Roxburgh's original 

 plant seems to have been smaller than what is usual. The 

 Howers are white or cream-coloured, with a long red stamen. In 

 many of the specimens the spike is slightly nodding, rather it is 

 ascending on a somewhat declined or decumbent stem ; an 

 appearance which has no value as a specific character, and which 

 occurs veiy often, especially where the inflorescence is large and 

 heavy. 



0. H. deusiflonnn ; glabrum, foliis ellipticis, bracteis unifloris, 

 laciniis limbi interioribus cuneiformibus, labelli subsessilis 

 ovato-lanceolati bifidi lobis acutis, stamine sequante, anthera 

 carnosa dorso convexa. 

 H. densiflorura, Wall. Cat. Herb. n. 65.59. 

 Only FOUND on Mount Shivapura in Nipal, and in Sikkira at 

 an elevation of 5 — 6000 feet by Dr. Hooker. 



I am not quite confident that this is in reality distinct from 

 H. gracile, as a species. The latter, however, has never been 

 found either in Nipal, or on the mountains to the westward of it. 

 The flowers ai'e orange-coloured throughout.
