irostelium rhomboidal, narrowly three-toothed m front ; stigma- 

 tiferous lobe cordate-reniform emarginate, about as long as the 

 rostellum but much wider ; ovary oblong slender straight. 



Described from several living and dried specimens from 

 different localities. Flowers creamy white, or pale rose, or lilac, 

 always with purple spots or stripes on the petals, and on the 

 inside of the lip, and sometimes on the middle sepal. The floral 

 characters seem pretty constant, but the vegetative are variable: 

 sometimes it is a stout-stemmed, many flowered, handsome 

 plant, with large loose sheaths : sometimes slender, the sheaths 

 greatly reduced, and the flowers much fewer.
