476 MR. G. BENTHAM ON AFRICAN ANONACE.E

This is a large genus widely spread over the warmer regions of America, and repre- 
sented in Africa by three species, all belonging to Martius's section Guanabani, one of 
them identical with an American one and the two others nearly allied to corresponding 
American ones, and in Madagascar by two species of a peculiar type ; but none are known 
in a wild state in Asia. Besides the above, four species (A. muricata of the section 
Guanabani and A. squamosa, A. reticulata, and A. Cherimolia of the section Atta) are 
more or less abundantly cultivated for their fruits in Africa as well as in Asia ; and 
specimens are not unfrequently transmitted by collectors without indication of their 
cultivated origin, so as to have given the idea that one or other of them are indigenous 
to the Old World. The union of the carpels into a single fruit with numerous one- 
seeded cells radiating from a central fleshy torus readily distinguishes the genus from all 
other African or Asiatic ones.

This is a somewhat doubtful species. A specimen of Heudelot's, which Guillemm 
thought he could identify with Thonning's plant, appears to me to be a nearly glabrous 
variety of A. senegalensis ; but Thonning describes the leaves as narrower and acute at 
the base, which I have never seen in A. senegalensis, — besides that one would infer from 
the expression he uses that the inner petals are broad. His plant may therefore be a 
distinct species as yet unknown to us.
