below, 9- to 10-jointed, terminating above in a narrowly 
ellipsoid or fusiform pseudobulb which is 5.8-8.1 em. long 
and bifoliate at the apex. At the proximal end of the rhi- 
zome is a short (immature) stem of similar character to 
the mature stem which is entirely concealed by distichous 
imbricating sheaths (necessarily broader where covering 
the terminal pseudobulbous portion) with spreading re- 
curved apices. Leaves two, elliptic to oblong-elliptic, 
11.5-21.2 cm. long, about 8.5—5 cm. wide, cuneate below, 
obtuse with a minutely bilobed and apiculate apex, with 
the mid-nerve conspicuously sulecate on the upper surface 
and carinate beneath, chartaceous in the dried specimen. 
Inflorescences short, axillary, few-flowered, decurved ra- 
cemes which are apparently subumbellate. Floral bracts 
distichously imbricating, loose, conduplicate, apparently 
suborbicular to ovate-elliptic when expanded. Flowers 
rather large for the genus, apparently ringent in natural 
position, somewhat fleshy. Dorsal sepal and petals appar- 
ently connivent to form a hood surrounding the column. 
Dorsal sepal oblong or lanceolate-oblong, strongly con- 
cave, subacute, about 14.2-15 mm. long and 4—5 mm. 
wide when spread out. Lateral sepals faleate-oblong- 
lanceolate, lightly navicular, saccate at the base, more or 
less spreading, about 12.4 mm. long from the posterior 
margin at the base to the apex, up to 4.7 mm. wide near 
the oblique base when expanded, acute. Petals oblanceo- 
late-oblong or lanceolate-oblong, faleate, acute or mi- 
nutely and sharply retuse, concave and incurved above, 
obliquely rounded at the base, about 12.5 mm. long and 
4—4.5 mm. wide. Lip in natural position with the basal 
portion erect and parallel to the column and the anterior 
part abruptly decurved; dise when forcibly spread out 
obovate in outline, shallowly retuse, distinctly 8-lobed 
above the middle, about 12—12.9 mm. long in the middle 
and 9 mm. wide across the lateral lobes when expanded,
