N. B. Name from hs (bis) and m§x (peraj, as 

 both the horizontal lateral leaflets are 

 furnished with a small bag or short spur. 



This genus comes nearest to the foregoing, but 

 is distinguishable from it by the spurs of 

 the lateral leaflets, by the insertion of the 

 labellum, the structure of the anther, 

 and the situation of the stigma.
