54 ORCHIDS OF THE SIKKIM-HIMALAYA. 
Sikkim; at Tendong, elevation about 3,000 feet; Pantling; in flower during May 
and June. Nepal; Wallich. Kamaon; Strachey and Уда. Khasia Hills, 
elevation 5,000 to 6,000 feet.; G. Mann. Shan Hills in Burmah; King's Collector. 
The flowers of this handsome species are of rather а dark yellow, the lip having 
а large purple blotch near its centre, and its edges being of a paler yellow than the 
rest of the flower. It has been collected only once in Sikkim; and in Assam, the 
Khasia Hills, and Upper Burmah, where it occurs more plentifully than in Sikkim, it 
is by no means abundant. Specimens were collected many years ago in Nepal by 
Wallich, and in Kamaon by Strachey and Winterbotham; but of late years it does 
not appear to have been found in the Western Himalaya.
