Ascochilus Ridl. in Journ. Linn. Soc. Bot. 82: 3874, 
Nov. 2, 1896. 
Lectotype: Ascochilus siamensis Ridl. 
Characterized by the distinct column-foot which con- 
tinues as a fleshy backwall in the lip. Lip very fleshy, 
practically solid with a very narrow, almost hair-thin 
tube extending in its full length; the entrance to this 
tube is a narrow slit at the base of the lip. Pollinia 2, 
slightly notched on slender stipe. 
The genus must be typified by Ascochilus siamensis 
for Ridley’s generic description is drawn primarily from 
that plant. Holttum’s contention that A scochilus is refer- 
able to Pteroceras is not tenable, for the latter genus has 
a differently constructed lip and the column-foot is not 
continuous with the lip. 
A scochilus calceolaris (Teijs. & Binn.) Garay show- 
ing the generic characters is illustrated by J. J. Smith, 
Orch. Java, fig. 423 under a wrong identification as Sar- 
cochilus emarginatus Rehb.f. Ascochilus pulvinatus Guil- 
laum. is Thriaspermum merguense (Hook.f.) O. Ktze. 
and Ascochilus vietnamensis Guillaum. is Malleola den- 
hifera J.J.Sm.
