whereas in 7°. Wenzelii the peduncles are subequal to the 
leaves in length. In 7. angustatum the leaves are com- 
paratively much narrower than those of 7. Wenzelit. 
Florally the present species may be distinguished from 
T. Wenzelu by the much narrower sepals and petals, by 
the narrow mid-lobe of the lip and by the more pro- 
nounced sac (or spur).

Thrixspermum Weberi, which is known from but 
one locality in the Philippines, is one of the most easily 
distinguished species of the subgenus Dendrocolla in the 
Philippines by reason of its comparatively very large, 
strongly flattened stems and its distinctive facies.

Schlechter proposed the section Katocolla (Orchis 5 
(1911) 54) for this and other species. I am unable to pass 
upon the validity of the section. 
Ames in Merrill Enum. Philipp. Flow. Pl. 1 (1925)

ing J.J.Smith. I have not verified this reduction.
