This is closely allied to C. herincea, Lindl., but differs in tho manner noted
under tliat species. The sepals and petals of this are of a yellowish-green and the
lip while with an elongated patch of yellow along its middle. Tho flowers have
tho perfume of primroses.

Sikkim, at elevations of from 4,000 to 6,000 feet; Eookor fil., King; Pantling,
at Rungbee, 6,000 feet, No. 80; in flower during June.
The sepals and petals are green, and tho lip pure while except its callus which
is yellow. Tho upper halves of the sepals and petals are sometimes ochreous yellow.

the lower halves being groon. This species is very closely allied to C. ciihrolema, Lindi.,
but differs from it in having fewer flowers in its raceme, somewhat larger floral braeti),
and a much longer spur. Moreover in this the a[ncal lobuli of the lip are entire, narrowly
oblong and diverging; while in 0. cithroleim those lobuli are crenate, broad, rounded,
and not diverging. The flowers of this aro hrodorous, while those of 0. ehlarmtha are
tlolightfuiiy fragrant.

Tho flowers .ai-e of an almost uniform violet tint, becomhig of a msty eolouiwhen
beginning to wither. The calli on the lip are yellow. Tho coloration, however
varies. In tho form which was named C. arsieohr the perianth is white, tho lip
