Lindley places this fine plant in his section Holochrysa, 
correctly noticing its affinity with D. chrysanthum (Bot. 
Mag., t. 1299), from which, however, it differs totally in 
inflorescence and in wanting the crenated wings on the back 
of the sepals and petals. In my apprehension it is still 
nearer to D. fimbriatum, Hook. (Tab. nost 4160), a native of 
the same countries, but which has larger flowers and narrower 
leaves, and a much more rigid rachis of the raceme. The 
double spot on the labellum of D. fuscatum might be supposed 
to indicate a specific difference between this and D. jim- 
briatum ; but’ whereas the type of the latter species has a 
whole-coloured lip, the var. oculatum (Bot. Mag. supra) has 
a large blotch, which, if divided into two, would represent the 
markings of D. fuscatum. 
D. fuscatum was first known from specimens collected by 
myself in the hot valleys of the Sikkim Himalaya and the 
-Khasia Mountains in 1848-1850, where it is far from 
uncommon. A fine drawing of it (by a native artist) exists 
in the Cathcart collection of Himalayan plants at Kew, and 
represents many racemes from one stem, one of which has 
fifteen flowers, all of a much deeper orange, almost orange- 
brown, colour than in our figure. The specimen here figured
