140 NEW OK RARE MALAYAN PLANTS. 



Sarawak: Knelling (Hewitt). 



A very odd little thing. The habit is quite that of a 

 Dcndrocolla, but the lip is very curious, the side lobes 

 meet together in the middle line leaving only a slit as 

 an entrance to the spur ; the main part of these is depress- 

 ed so as to form a flat disc, beneath is a minute midlobe. 

 The spur is more like that of a Saccolabium.
