The lip is very curiously constructed. It looks like a 
side saddle with two horns instead of one; the sac, into 
which there is an opening only between the horns, is 
almost concealed by the lamina which hangs down in the 
manner of saddle-flaps. The column is reclining with a 
prominent bilobed vertical rostellum.
