BORDER AREA NAY PYI TAW – SHAN. Fide Aung et al. (2020: 71) . SHAN. Loilen District : 2285 m, 2 May 1939, Dickason 8321 ( AMES) .

Distribution:— The Himalayas, northeastern India, Myanmar and southwestern China.

Notes:— Considering the variability of this species, it seems likely that C. hitendrae S.Das & S.K.Jain from India is not different from C. corymbosa . Dickason 7772 has only a young inflorescence but seems to belong here. Kermode 17357 at AMES is a mixture of a sterile Coelogyne plant and a flower of Cymbidium mastersii Griff. ex Lindl. in the packet.

( RAF [s]); Myitkyina District : type .

Distribution:— Northern Myanmar and southwestern China.

Note:— The correct position of C. tsii needs more study. The relationships of C. ecarinata , C. ustulata C.S.P.Parish & Rchb. f. and C. tsii remain unsettled.
