sheaths. Bracts like the sheaths of the scape, but broader. 

 Flower shortly pedicelled, pale yellow, except the ovary 

 which is streaked with bright red. Perianth about an inch 

 long and nearly as broad ; sepals coriaceous, strongly three- 

 ribbed, united for about a third of their length into an in- 

 flated very gibbous cup with an almost truncate base ; 

 dorsal sepal triangular- ovate, acuminate, recurved, lateral 

 rather narrower and shorter. Petals erect on each side of 

 the column, and as long as the latter, linear, dilating into 

 an obliquely tetragonal limb. Lip sessile, broadly oblong, 

 nearly flat, yellow suffused with red-brown, obscurely three- 

 nerved towards the base, tip rounded, distal third above 

 granulate. Column stout, apex dilated, rounded and 

 irregularly crenate. Pollinia ovoid. — /. D. H.
