A very curious plant with the pseudobulbs of the Imbricate 
section, though narrower and more distant, but distinct in 
possessing the persistent empty bracts at the base of the raceme, 
like those of a Cologyne of the Prolifere section, while the 
floral bracts are very caducous. The plant might indeed be 
referred to Cælogyne were it not for the lip, which is that of a 
true Pholidota, having a saccate base ending in a flat portion 
bilobed at the apex and erose at the sides, with two flat triangular 
calli at the entrance to the saccate hypochil. The column has 
large wings narrowed gradually to the base.

I have examined a number of specimens of the Himalayan, 
Javan, Malayan, and Bornean forms of this plant, and have 
seen it abundant in a wild state in various parts of the Malay 
Peninsula, besides keeping considerable quantities under cultiva-
