Tho prevailing colour in tho flowers is white; but tho sepals arc tipped with
green externally, and the lip has a blotch of pale violet near the base, the largo
lobulate callosity however being bright yellow.

side lobes and in front of the mouth of the spur. Spur slender, long, cylindiic,
slightly curved, pubei-ulous, nearly as long as tho stalked ovary. Colitmn short; stigma
divided iuto two elongated halves by the entrance to the spur; arms of the rosteUum
oblong, blunt and projecting beyond tho lip of tho anther. Pollinia shrunken, attached
to a quadrate gland. Walp. Ann. VI, 916; Hook. fil. Fl. Br. Ind. V, 849.
At the base of the range to the east of the Jaldacca liver, at an elevation of
about 800 feet; in flower dming April; PantUng, No. 440. Khasia Hills; Lobb,

The flowers, which are pure wliite and have a sweet smell, resemble those of
C, odora, GrifE., although the latter have a spur- longer than the ovary, aud the flowers
and leaves arc not contemporaneous as in this. The specimens of C. odora are very
scanty, but an examination of them leads us to believe that C. odora and C. awjusta
are probably only different names for the same species.
