obovatum, antice late rotundatum, concavum, dense 
longe ciliatum. Columna perbrevis. 
Plant terrestrial, slender, about 21.5 cm. tall. Roots 
tuberous, fasciculate, slender, lanuginose. Leaves several, 
the four basal blades rosulate, slender-petioled; lamina 
ovate, acute or short-acuminate, broadly cuneate to sub- 
truncate at the base, commonly 3.2-3.5 cm. long, up to 
2.2 cm. wide; petiole channelled, slightly dilated above 
and below, about 2 cm. or less long. A fourth similar 
but sessile leaf rises near the base of the stem. Stem 
slender, glabrous in the lower portion, densely glandular- 
pubescent above, bearing four distant sheaths of which 
the lower ones have a close long-sheathing tubular base 
and the lowermost is dilated into a small foliaceous blade. 
Raceme loosely 17-flowered, about 4.5 cm. long, with 
the apical portion (bearing immature flowers) nodding. 
Flowers small, but medium-sized for the genus, mem- 
branaceous. Sepals very sparingly glandular-pubescent 
on the outer surface. Dorsal sepal elliptic, acute, con- 
cave, 3-nerved with the lateral nerves branching below, 
about 5.9 mm. long and 8.2 mm. wide when expanded. 
Lateral sepals oval, acute, concave, 5-nerved, about 5.6 
mm. long and 8.2 mm. wide. Petals obliquely elliptic, 
acute or subacute, 4-nerved, densely ciliate with the cilia 
longer on the anterior margin, about 5 mm. long and 
2.7 mm. wide. Lip simple, cuneate-obovate, broadly 
rounded in front, minutely acute at the apex, densely 
long-ciliate, about 4 mm. long and 3 mm. wide near the 
front in natural position, rather deeply concave especially 
above, 3-nerved, the lateral shorter nerves recurved in 
the middle of the lamina and having two or three short 
recurved branches. Column very short, with the stalk 
of the anther arising near the base. 
The long-ciliate lip seems to be unique in the genus 
and the ciliate petals are remarkably broad.
