This closely resembles A. Burchellii, Schlechter, but differs from that species by 
the presence of the falcate recurved tooth at the top of the corona-lobes and by 
the follicles abruptly contracted into a beak, not gradually tapering to the 
apex, and, when they open, the basal part remains very much more concave and 
bag-like than in A. Burchellii.
