orbicular-ovoid, compressed, with blunt margins, obscurely 
grooved, quite smooth and even, not contracted into a neck; 
spathes narrowly lanceolate, acuminate, brown, equalling 
the pseudo-bulb. Leaves two from each pseudo-bulb, five 
to seven inches long by one half an inch broad, obtuse, 
keeled, narrowed at the base, deep green, midrib yellowish. 
Scapes from the base of the pseudo-bulb, much shorter than 
the leaves, one-flowered, with four to six green subacute 
sheathing bracts, the lower of which are imbricate; the 
uppermost is three-quarters of an inch long, rather inflated, 
obtuse, almost as long as the ovary. Flowers about one and 
a quarter inch broad, pale golden-yellow within, with a 
purple median stripe towards the base of the petals, paler 
without. Sepals incurved, dorsal arching, linear-oblong, 
subacute; lateral more lanceolate, much broader at the base, 
somewhat deflexed. Petals shorter than the sepals, ascend- 
ing and incurved, their tips meeting under the dorsal sepal, 
narrowly linear-oblong, subacute. Lip rather shorter than 
the petals, three-lobed, claw short, sharply incurved; lateral 
lobes ear-shaped, erect, margins incurved, yellow streaked 
with purple; mid-lobe larger, orbicular-oblong, tip rounded, 
nearly flat, with a tubercular callus at the base, pale golden- 
yellow. Column slender, purple. Pollen-masses two, 
ellipsoid, each furrowed in front; caudicle short, small, 
subglobose; gland ragged.—J. D. H.
