[his species may be recognised trom all other species 
except 4. refractus (XKraenzl.) Summerh. by the lax few- 
flowered but short inflorescences, the entire ovate lip and 
long slender column. The leaves are similar to those in 
A. glomeratus (Ridl.) Summerh. or A. ovatus Summerh. 
The pollinarium stipes is divided in the upper part while 
I | per | 
the viscidium is lanceolate and exceptionally large (over 
8 mm. long altogether).

Easily recognised by the very short spur (2-3 mm. 
long) and broad almost orbicular lip with indistinct side 
lobes more or less enclosing the column. The leaves vary 
considerably in width and in the inequality of the apical 
lobing, but are usually rather narrow. A specimen from 
Mt. Mlinga, East Usambaras, Tanganyika ‘Territory, 
collected by W.M. Moreau (No. 871) seems to be near- 
est this species but is more robust with broad leaves, 
slightly larger flowers and a spur nearly 4.5 mm. long.
