Dr. Lindley lias well remarked in describing this species, 

 that it differs from all its congeners of the Pleione group in 

 leafing and flowering at the same time ; I do not, however, 

 understand his statement to the effect that it further difiers 

 in that " the parts of the flower do not taper to the base, 

 for in this respect I see no difference between it and other 

 Pleiones. There are certainly either two forms of this m the 

 Sikkim mountains, or the lip affords a very variable 

 character; of these forms I made drawings m Sikkim from 

 wild specimens; one of them agrees admirably with 

 that here given, but in the other the lip is not convolute in- 

 to a cylinder for three-fourths of its length, and then 

 expanded into a trumpet-shaped spotted mouth ; but is more 

 open from the base, like a coal-scuttle or scoop, and is 

 rhomboid when spread open, and there is further no distinc- 

 tion between the lobes ; and there are no spots. This last 

 form occurred at a higher elevation (9-10,000 ft.) than the 

 other, which grows at 7-8000 ft., and I have seen a 

 specimen of it gathered by Jacquemont, No. 208, (^04 

 Herb. Paris) in the Western Himalaya. Dr. Lindley has 

 included both the forms under the same name.
