Plant stout but small for its alliance. Stem stout, 
about 47 cm. or less in height, loosely forking with erect- 
ascending branches, entirely concealed by distichous im- 
bricating sheaths or leaf-sheaths. Leaves elliptic-oblong 
to narrowly oblong (rarely ovate-oblong), acute or sub- 
acute, amplexicaul at the slightly narrowed base, up to 
12 cm. long and 2.2 cm. wide (usually smaller), with the 
upper margins minutely serrulate. Flowers small, axil- 
lary, cupuliform, deep yellow. Sepals connate near the 
base. Dorsal sepal ovate, acute, concave, about 9 mm. 
long and 5.8 mm. wide. Lateral sepals oblong-ovate, 
very slightly oblique, a little longer and narrower than 
the dorsal sepal. Petals oblanceolate-oblong to cuneate- 
elliptic, abruptly acute or apiculate, about 7.3 mm. long 
and 8 mm. wide above. Lip sigmoid when viewed from 
the side, fleshy, distinctly shorter than the sepals; lower 
portion broadly cuneate, concave; median portion con- 
sisting of a pair of erect semiorbicular lobes separated by 
a fleshy more or less sulcate callus; anterior portion sub- 
quadrate-ovate, apparently retuse, with a short but prom- 
inent conical boss beneath. Column small, incurved and 
dilated above, produced into a short foot. Ovary slender, 
triquetrous, developing into a triquetrous-ellipsoid fruit.
