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.
