merh, 
The species of this section may be distinguished from 
those of Section | by their usually larger flowers and 
longer spur. The lamina of the lip is relatively short, 
though sometimes quite broad, and may be markedly 
concave. The column is much higher at the back than in 
front, the androclinium consequently rising steeply from 
its front margin. The rostellum is usually quite long and 
either produced downwards for its whole length or the 
lower part more or less adpressed to the column and the 
distal part curving upwards and forwards. In agreement 
with this the anther is often extended in front to form a 
long point covering the pollinarium. The stipes is usu- 
ally long and slender while the viscidium is more elon- 
gated in shape than in sect. Hu-microcoelia. In several 
species the stipes is divided in the upper part, one pol- 
lintum being attached to each branch.

On account of the column characters, particularly the 
sloping androclinium, the forked stipes to the pollinia and 
the orange color of the flowers this species seems properly 
placed in this section. It differs from M. H/hotu (Kinet) 
Summerh. in the narrower lip, the shorter spur and the
