ovate, acute, keeled, brown, scarious, appressed. Leaves, 
two at the top of the pseudobulb, six to seven inches long, 
erect, recurved above the middle, acute, narrowed into a short 
petiole, obscurely nerved, keeled at the costa beneath, bright 
green ; articulate at the base with a globose joint or internode, 
that persists in the old pseudobulbs. Laceme produced at 
the base of the last-formed pseudobulb, ascending from its 
base, where it bursts through the sheath; peduncle stout, 
stiff, ascending, clothed with broad obtuse convolute green 
scales ; rachis erect, slender, flexuous, floriferous from the 
base upwards, about 5-flowered. Flowers one anda half 
inch diameter, distichous; bracts two thirds inch long, 
horizontal, cymbiform, exceeding the ovary, membra- 
nous. Sepals and petals similar, linear-oblong or lanceo- 
late, acuminate, recurved, keeled, pale yellow-green. Lip 
rather longer than the sepals, white with a broad ochreous 
blotch on the mid-lobe, the margins of the lateral 
lobes brown and as well as the disk freckled with brown; 
lateral lobes rounded; mid-lobe with a broad flat claw, 
broadly trowel-shaped, tip acuminate recurved, margins undu- 
late, disk with three slender crenate ridges, of which the middle 
one is shortest. Column slender, narrowly winged.—/. D. H.
