The general habit, as well as the shape of the lip, agrees so well with the 
above figure that I think both must belong to the same species.

Hab. Kinabalu, below Pakapaka, 9000', terrestrial, in open scrub on

A very curious plant of the Cælogyne group, closely resembling Gymno- 
glottis, J. J. Sm., in habit, but differing in having the lip free from the 
column, and strongly sigmatoid in shape, the latter character being com- 
memorated in the generic name.
