 forest. (H. A. B. BiiNNEMEljER nrs. 9924, 10085 and 10236, May 1920). 



I hâve no doubt that PLatyclinis insectifcra RiDL. is intended for this 

 plant tliough the petals are not carinate. 



From the dry spécimens and the flowers preserved in alcohol the 

 sepr.ls appear to hâve been pale with two longitudinal brown bars except 

 the base, the petals brown except the base, the lip brown with a pale 

 longitudinal line, the column pale dotted brown in the upper part and 

 with the stelidia brown for the greater part.
