breaking down of trichome-like structures at an early period in the 

 development of the flowers. In mature flowers this farinaceous 

 substance soon passes away. The central callus of the basal trio is 

 curved backward and is much taller than its companions; the lat- 

 eral calli are membranaceous, triangular, obtuse, purplish in color 

 and posteriorly shortly carinate. The large fleshy callus on the mid- 

 dle lobe is flattened laterally, is 2 mm. tall and is blunt at the apex.
