BENTHAM ON AFRICAN ANONACEiE 
( Whitfield) . At Nupe on the 
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. 
1. H. senegalensis, A. DC. Mem. Anon. 37 ; foliis ovali-ellipticis oblongisve supra gla- 
bris subtus puberulis, floribus sessilibus, petalis lineari-lanceolatis acutiusculis undu- 
latis extus incano-puberulis. 
Uvaria monopetala, Guill. et Perr. Fl. Seneg. 8, t. 2. 
Senegambia (Leprieur and Perrottet; Heudelot, n. 360). On the 
Niger {Barter). 
I had at first considered Barter's specimens as belonging to a different 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 f to 1J 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. 
2. H. grandiflorus, sp. n. ; foliis petiolatis elliptico-oblongis acuminatis glabris, flori- 
bus pedicellatis, pedicellis sepalisque ferrugineo-sericeis, petalis longe lanceolatis. 
Arbor 60-pedalis, inflorescentia excepta glaber. Eolia 4-8 poll, longa, circiter 
2 poll, lata, acumine longo, basi obtusiuscula petiolo 3-4-lineari fulta, chartacea v. 
tenuiter coriacea, glaberrima, costa subtus prominula, nervis primariis utrmque 
circiter 15. Pedunculi axillares, solitarii v. gemini, semipollicares, 1-2-flori, dense 
ferrugineo-sericei. Bractea ad basin pedicelli 3 lin. longa, angusta, basi convoluta, 
caducissima. Bracteolse in pedicello 2 opposite, basi connatae, ferrugmeo-senceae. 
Sepala ovata, concava, crassiuscula, 4-5 lin. longa. Petala perfecte evoluta ultra 
1J poll, longa, alba, transverse undulata, extus pube minute canescentia, basi in 
tubum densius pubescentem 2 lin. longum connata. Antherae numerosa?, connectivo 
more generis ultra loculos truncato-dilatato. Carpella 10-12, villosa, 2-seriatim 
pluriovulata ; styli breves, reflexi, profunde bilobi, lobis dilatatis apice subtus stig- 
matosis. Baeese 3-4, fere lignosse, dense ferrugineo-tomentosae, sessiles, 3 poll. 
long?e, 1J poll, crassse. Semina transversa, in quoque loculo ultra 12, singula ultra 
pollicem longa, septis spuriis transversis (pulpa exsiccata ?) separata. 
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.
