graecum while the bracts are triangular-ovate and com- 
paratively short. The lip is distinctly trilobed, the mid- 
dle lobe being more or less concave with an undulate 
somewhat infolded margin. The S-shaped spur separates 
the species from the Cephalangraecum species, but is also 
found in A. recurvus Finet and two Tanganyika species.

Distinguished by the slightly unequal apical lobes of 
the leaves which are rounded or slightly retuse or bilobu- 
late but not denticulate, the very broad lip with the 
rounded almost hastate base enveloping the column and 
the relatively long spur. It may be necessary to reduce 
this species to A. cephalotes (Rehb.f.) Summerh. when 
the type specimen of the latter has been examined.
