D. fragrans, Hortul. 
Though differing in many respects from the type of the 
section Stachyobium, and especially in the lateral subsessile 
few-fld. inflorescence, I am disposed to follow Mr. Rolfe 
in placing this species in that group, and near to D. bar- 
batulum, Lindl. (see tab. 5918), and D. Fytcheanum (tab. 
5444, under the name of barbatum). It differs from both 
these species in the long, very slender branched stems, but 
agrees in the hairy disk of the flat lip, and the minute 
coloured lateral lobes of the latter. The colour of the lip 
appears to be variable, for Mr. Rolfe describes its side lobes 
as pale green, with light brown radiating nerves. 
D. sarmentosum is a native of the Shan States of Upper 
Burma, where it was discovered by Mr. R. Moore, when 
Officiating Assistant Superintendent of the Upper Shan 
States, who alludes to it in a very interesting paper con- 
tributed to the Orchid Review (vol. iii. (1895) p. 171) on 
the Orchids of those states as one of thirty-five Orchids 
(eighteen of them Dendrobia) occurring within a radius of 
thirty miles round Lake Inle. 
It first flowered in the collection of Messrs. W. L. 
Lewis & Co. early in 1895. The specimen here figured 
Marcu Ist, 1897.
