lacerated scales, and above bearing two, elongated, linear 

 leaves, which vary much in length on different pseudo- 

 bulbs. Scape radical, generally exceeding the leaves in 

 length, articulated and with bracteal scales at the joints. 

 Flowers in an oblong, rather lax spike, or raceme, every 

 part white, except the crest of the labellum and the anthers, 

 which are yellow, the former spotted with red. Sepals and 

 petals spreading, ovate or (the petals more especially) 

 obovate, rather acute, waved. Labellum broadly oblong, 

 acute, three-lobed, the side lobes short and reflexed, the 

 middle lobe large and bent back : on the disk, at the base, 

 is a large, fleshy-colored crest or excrescence, three-lobed 

 at the side next the column, two-lobed at the opposite one. 

 Column very short, with a wing on each side, and another 

 at the back of the anther, all fimbriated or serrated at the 

 apices. Anther-case hemisphaerical. Pollen-masses two, 

 obovate, fixed to a rather large gland.
