Characterised by the short leaves and small flowers 
which are about the same size as those of “4. Straussii 
(Schltr.) Schltr. The lip, however, is much broader than 
in that species, while the spur is almost globular and 
shorter than the lip. In uf. parviflorus the rostellum, al- 
though agreeing in general features with that of the other 
species of the genus, is turned up tor only a short dis- 
tance at the apex.

munima parte. 
This species, which I consider to be the type of the 
genus, resembles l.clandestinus (Lindl) Schltr., but the 
leaves are consistently shorter and relatively broader 
while the lobes are less unequal and subacute or almost 
rounded and very shortly lobulate. Florally the species 
has the trilobed lip, somewhat S-shaped spur and only 
slightly bilobed pollinarium stipes of A. clandestinus.

It is difficult to see why Schlechter referred this spe- 
cies to Cyrtorchis since Kraenzlin described clearly the 
obese!
