visa; pollinia ellipsoideo-globosa, 0.5 mm. longa, stipiti- 
bus linearibus 0.3 mm. longis, viscidiis distinctis quad- 
ratis minutis; rostellum breviter productum, viscidiis

Chiefly recognisable by the relatively broad oblong- 
elliptical leaves. In floral structure it is nearly related to 
the Comoro Islands A. trifurca (Rehb.f.) Schltr. It is 
a larger plant than either of the other three species from 
this general region (A. ischnopus (Schltr.) Schltr., A. 
dolabriformis (Rolfe) Schltr. and 4. tridens (Lindl. ) 
Schltr.) and may also be distinguished by the details of 
the flowers. A specimen collected by J. W. Purseglove 
(no. 2614) at Goma near Lake Kivu in the Belgian Con- 
go, is probably also referable to this species, but the plants 
are considerably smaller and unfortunately none of the 
flowers is preserved completely.
