convex, but with a central groove covered with capitate hairs, the margir»
fringed with similar hairs. Column stout, its foot very short,, its apical teeth small,

Tlie flowers are in the main white, but the i
Moulmeio; R. Seott. Also found
epals and back of the column and
its foot are tinged with yellow. The flowers are
t-smelling. Some specimens in
the Calcutta herbarium are noted as having been found at so low an elevation
1,000 feet in the Teesta valley. The elevation at which the specimens from the
Khasia Hills and Burma were collected is not known. No ñervos are visible in the
sepals or petals when fresh. Plants from higt elevations have longer flowers than
tliose from lower levels.
