This very remarkable species has the habit of O. variegatum, and teira- 
petalum, from both which it is readily distinguished by the large lateral 
lobes of its labellum, and the cymbiform upper sepal. Its crest is also 
essentially different, consisting of three narrow nearly equal collateral 
elevati calli, in front of which is placed a short tubercle. 
Its flowers are pure white with a little orange about the crest of the 
lip. The column is pink.
