be ascertained with reasonable certainty. | have not seen 
a few of the species and for the moment the position of 
these must remain doubtful. Some name changes may 
be necessary when they have been investigated properly. 
The type specimens of the two new species are in the 
Kew Herbarium. 
1. Ancistrorhynchus brevifolius /net in Mém. 
Soc. Bot. France 9 (1907) 45, t. IX, figs. 1-14—

Krom the description and illustration this species pos- 
sesses the pollinarium of 4. reeurvus and leaves similar 
to those of many Cephalangraecums, that is, V-shaped 
in section with rounded apical lobes. The very broad tri- 
lobed lip and divergent spur are also characteristic.
