TANGANYIKA TreRrITORY: East Usambaras, Amani, 900 m, alt., on 
exotic coniferous trees, July 1941, Moreau 68 (Type). 
This species strongly resembles A. tenuicalear Sum- 
merh. in general appearance and in floral structure, and 
has the same type of pollinarium. However, the inflores- 
cences are shorter, the flowers pale green and unscented 
while the sepals are approximately equal in length, in- 
stead of the laterals being much longer than the dorsal 
as in A. tenwicalear. The spur, though of about the same 
length, is distinctly thicker. A striking feature is the 
thickened distal portions of the tepals which are furnished 
with numerous crystal sacs appearing as even denser 
points in the tissue.
