diverging and making the callus V-shaped in transverse 
section. The stipes of the pollinarium is broadened in the 
upper half to form a flattened plate which is wrapped 
around the greater part of the pollinia; these arise some 
distance below the apex on a slightly less sloping or hor- 
izontal portion of the widened area. ‘These features are 
developed to a much less extent in some of the species 
of the section Dicranotaenia ot Microcoelia.
