1 4 2 OECniDS OF THE SIKSIU-HIJIALAYA.
A gonus which forms a ocnnocting link between Ccclogyne and OtocMha, but differs from both
in the curious sigmoid flexure of the base of the lip. The lip, Hke that of Olochilas, has no latoellaj,
whereas iu Coehijyne a laniellated diso is the rule. There are two sjiecios—the following and auotlier
named F. apicidata.

and southwards to the Xaga, Kliasla and Btmnoso lifll ranges.
In Sikklm tlis species iorms lai-ge masses, often breaking down thick branches of
trees by their weight. The ilowers are white, there being, howcTor, a patch of
brown on the sac of the lip and the cohnnn being altogether brown, as is tho rachis.
