Descr. Pseudo-bulbs clustered, elongated, clavate, cloth- 
ed with membranous sheaths, and bearing a large, solitary, 
coriaceous leaf at the extremity. From the axil of that 
leaf proceeds a large, compressed, sheathing, yellow-green 
spatha, with an oblique mouth, through which the spike, of 
five or six large, handsome, and fragrant flowers emerges. 
Sepals oblong, spathulate, their margins revolute, but not 
crisped, white or cream-colour, with a faint, purplish tinge. 
Petals also spreading, about equal in length with the sepals, 
but much broader, and the margins, especially in the upper 
half, singularly waved and crisped. Lip standing forward, 
recurved at the apex, oblong, acute, three-lobed, the lower 
or side-lobes rounded, white, yellow at the base and streak- 
ed with red, the middle or terminal one ovate, acuminate, 
the margin rich red-purple with deeper purple veins, all of 
them remarkably waved and crisped. Column and anther- 
case, &c., as in the Genus.
