468 MR. G. BENTHAM ON AFRICAN ANONACE^. 



have- been described by several authors as imbricate, with one outside ; but in the only 

 young bud I have been able to examine with care they were certainly valvate in each 

 series, this arrangement being somewhat disguised, when the bud is ready to open, by 

 the increased folds of the petals.

 Senegambia {Leprieur and Perrottet; Heudelot, n. 360). On the Gambia {Whitfield). At Nupe on the 



Niger [Bai'ter). 

 I had at first considered Barter's specimens as belonging to a difPerent species from 

 the Senegambian ones, with longer, narrower and less obtuse leaves and narrower petals ; 

 but a further comparison of all our specimens convinces me that they all belong to one 

 species. The leaves are, in Perrottet's specimen, not 2 in. long and f in. broad ; in 

 Heudelot's, 4 in. long and 1^ in. broad ; in Barter's, 4 to 5 in. long and only | to 1| in. 

 broad ; but these agree the best in general form with the figure in the ' Flora Senegam- 

 bise' ; and the petals alter very much in shape as they grow out.

 Ambas Bay, West Africa (G. Mann). On the Niger River {Barter). 



The flowers are described from Mann's specimens ; the fruit from a single specimen 

 of Barter's without flower, but which, from a comparison of the bark, foliage, and in- 

 florescence, evidently belongs to the same species.
