THE OBCHIDOLOGT OF INDIA. 47 



260. E. MuscicoLA; foliis binis lanceolatis basi angustatis scapo apice 

 bifloro aequalibus, bracteis cucuUatis membranaceis cuspide herbaceo 

 flore breviore, sepalis petalisque lineari-lanceolatis aequalibus ascen- 

 dentibus, labello lanceolate canaliculato dorso pubescente. 



Dendrobium muscicola, Lindl. Gen. Sf Sp. 75. 



Ceylon, Champion, Gardner (853). 



I can only find 4 pyriform pollen-masses in the single ilower 

 at my disposal. The whole plant not more than 2 inches high. 

 Flowers resemble those of M^ia nana on a very small scale. 

 Since it has never been found among collections from the N. of 

 India, it is probable that the old locality " Nepal," was erroneous. 



261. E. mierochilos. (Dendrobium microchilos, Dalzell, in Hooker's 

 Journ. iii. 345.) 



On Mango trees in Western Bengal, Dalzell, Stocks (28). 



I have this as D.fimbriatum of Dalzell, out of Stocks' s her- 

 barium ; it is certainly distinct from that plant, although very 

 much like it. The flowers are smaller, more fleshy ; and the lip 

 is slightly unguiculate, then irregularly widened and thick-edged, 

 after which it contracts into a thin-edged acute apex. Only two 

 pairs of pollen-masses could be found in the flowers I dissected. 

 The tubercles at the base of the lip, spoken of by Mr. Dalzell, I 

 have not succeeded in finding. 



262. E. DalzelU. (Dendrobium Dalzelli, Hooker, Journ. Bot. iv. 292. 

 Dendr. fimbriatum, Dalzell, 1. c. — Dendr. filiforme, Wight, Ic. 1642.) 



Western Ghauts, on trees, Dalzell; hollow trees in the ruins. Stocks 

 (27); Concan, Law {hb. Hooker. 166, 91); Bombay Presidency, 

 Dalzell {hb. Hooker. 167). 

 I am not surprised at Mr. Dalzell' s having taken this for JE. 

 microchilos, as he tells us was the case ; for the two are exceed- 

 ingly similar, as is indeed shown by so accurate an observer as 

 Stocks having given the name of microchilos to specimens now 

 before me. The flowers are, however, rather larger and less fleshy ; 

 the lip is membranous, ovate-lanceolate, and distinctly serrulate to- 

 wards the point. As to the marginal glands of the sepals, which 

 gave rise to the nannejlmhriatum, they are very evanescent, and I 

 suspect sometimes altogether absent. They are hardly discover- 

 able in Mr. Law's Concan specimens. Imperfect specimens from 

 Ceylon (2353 Hb. Hooker.) probably belong here. Of the eight 

 pollen-masses, four are quite rudimentary. 



263. E. ARTicuLATA ; pscudobulbis oblongis in catenae speciem arti- 



culatis, foliis , scapo setaceo flexuoso 5-7-floro, bracteis ovatis 



cucuUatis, petalis acutis multo brevioribus. 



Ceylon, Mrs. General Walker {hb. Hooker.) ; Gardner.
