Descr. Pseudo-bulb none in our specimens. The leaves 
are from eight or ten inches to a foot long, and spring from 
the root, they are broadly lanceolate, glossy, yellow green, 
scarcely striated, waved, distichous, sheathing at the base. 
From the axil of one of the outer leaves arises the scape, 
scarcely of the length of one’s finger, erect, having two 
membranous, sheathing bracteas on the top at the base of 
the germen. Sepals and petals in one series, oblong, pale 
greenish-white, spreading, combined at the base: the 
petals rather smaller than the sepals, Lip very large, nearly 
Square, set on by a small short claw, very broad and cordate 
at the base, where it is ventricose, the sides involute and 
crisped, the apex reflexed, two-lobed : at the base within 
is a large, lunate, fleshy, depressed crest, lobed and cre- 
nated, marked with purple lines as is the lower half of the 
lip itself; but these lines soon combine, and form a large 
purple blotch in the upper half of the lip. Column short, 
semiterete, with two small wings above, white, the front 
delicately streaked with red. Anther-case obliquely coni- 
cal, obtuse.
