466 MR. G. BENTHAM ON AFRICAN ANONACEiE. 



Torus crassus, fere liemisphsericus, sub carpellis tamen planus v. leviter excavatus. 

 Stamina numerosissima angusta, connectivo apice capitulo parvo appendiculato. 

 Carpella numerosa, glabra, ovulis 12-15 biseriatis, stylis oblongo-clavatis ovario ipso 

 paullo brevioribus. Fructus non visus. 

 Ambas Bay and Fernando Po (G. Mann). 



Some large, ovoid, thick glabrous carpels, full 4 inches long, containing each three or 

 four seeds, separately gathered by Mr. Mann, may possibly belong to this species. 



5. U. ? FUSCA, sp. n. ; foKis amplis elongato-oblongis acuminatis infra medium angustatis 

 glabris, petiolo brevissimo, fioribiis subsessilibus bracteis imbricatis sepalisque ferru- 

 gineo-sericeis, petalis latis concavis leviter imbricatis subvalvatisque, antheris apice 

 truncatis, carpellis villosis. — Arbor 25-pedalis. Polia lis Z7. connicentis simillima, 

 fere pedalia. Flores gemini, subglobosi, poUicem diametro. Bractese plures, arete 

 imbricatse, interiores sepalis paullo minores, exteriores parvse. Sepala lata, basi 

 breviter connata. Petala lis TI. conniventis subsimilia sed minus crassa et vix 

 imbricata. Stamina ultra 2000, arctissime conferta. Carpella fere 100, villosa, 3-4- 

 ovulata, stigmate crasso brevi truncate, post anthesin jam paullo aucta sessilia, 

 falcato-oblonga. 



Fernando Po (G. Mann). 



The flowers of our specimen are scarcely sufl&cient to determine the affinities with 

 precision; but I believe it to be a JJvaria, near the last. Mr. Mann describes the 

 flowers as brown. 



Doubtful Species. 



U. ovata, DC. 



TJ. ovata, Schum. et Thonn. Beskr. PI. Guin. 255. 



TI. cylindrica, Schum. et Thonn. I. c. 256. 



I am unable to identify either of the above three species amongst our specimens. JJ. 

 cylindrica, with narrow lanceolate petals, may perhaps be a TJiiona. 



U. ? gracilis, Hook, f Fl. Nig. 210. We have no specimen ; but from the description 

 it is possibly a Clathrospermum. 



TJ. ? sp. with rather large sessile flowers, more imbricate, and without the bracts of TJ. 

 fusca, and shorter leaves, nearer those of TJ. Chamce. Fernando Po {G. Mann). A single 

 specimen with one imperfect flower. 



TJ. ? sp., named Kooharee in Sierra Leone. Fruits and one leaf only in the Kew 

 Museum. Not unlike TJ. Chamoi ; but the carpels are more villous, shorter and thicker, 

 on longer stalks. 



2. Artabotrys, R. Br. ; Benth. et Hook, f Gen. PI. 24. 



This is chiefly an Asiatic genus, represented in Africa by two species, having both of 



them the climbing habit and remarkable hooked peduncles of the Asiatic ones ; and 



one of them, the W. African A. macropliylla, has the same petals, thick, concave, and 



closely connivent at the base, with more or less spreading oblong or narrow laminae ;
