Individuals bisexual; inflorescences ramiflorous on old or young foliate branches, leaf opposed. Flowers with 9 perianth parts in 3 whorls, 1 to 2 per inflorescence; pedicel 10-20 mm long, 1-2 mm in diameter, brown tomentose; in fruit 25-50 mm long, 3-4 mm in diameter, pubescent; bracts 2, all basal, 1-4 mm long, 2-3 mm wide; sepals 3, valvate, free, 3-4 mm long, 3-4 mm wide, broadly triangular to circular, apex acute, base truncate, green, densely pubescent outside, glabrous inside, margins flat; petals free, outer longer than inner; outer petals 3, 10-15 mm long, 8-9 mm wide, ovate, apex acute, base truncate, yellow to green, margins flat, tomentose outside, glabrous inside; inner petals 3, valvate, 8-10 mm long, 3-4 mm wide, narrowly oblong or narrowly elliptic, apex acute, base truncate, yellow-green, margins flat, glabrous outside, glabrous inside; stamens numerous (not counted), 2-3 mm long, linear; connective discoid, shortly pubescent; staminodes absent; carpels free, numerous (not counted), ovary 1-2 mm long, stigma capitate, glabrous. Fruit pseudosyncarpous; 20-50 mm long, 20-30 mm in diameter, obovoid to globose, yellow orange at maturity, monocarps sessile, numerous, apex flat, glabrous, smooth, yellow to orange when ripe; seed 1, 8-10 mm long, 4-5 mm in diameter, flattened ellipsoid; aril absent. Distribution. A west, central and east African and northern Malagasy subspecies from Senegal to Mozambique; in Cameroon known from the Adamaoua, Central, East, Far North, North, North-West, South-West and West regions. Habitat. A common species; in lowland savanna regions towards the north, at higher altitudes towards the southern region, may, sometimes be the dominant tree species across the savanna. Altitude 100-1400 m a.s.l. Local and common names known in Cameroon. Falŏ (dial. Bamileke (Burkill 1985)); pomme-cannelle du Sénégal (French); African custard-apple; wild custard apple, wild soursop (English). Uses in Cameroon. food: fruit is eaten, flower for sauces, condiments, spices, flavourings; medicine: root as pain-killer, against diarrh dysentery, cholera, venereal diseases, bark used as vermifuges, diuretics, genital stimulants/depressants, lactation stimulants; construction: house building, furniture; dyes and tannins: astringents, insecticides, arachnicides; products: wood fire; fuel and lighting; social: religion, superstitions, magic. Notes. Annona senegalensis subsp. senegalensis is distinguished by the pubescence of the lower side of the leaf blade which ranges from densely pubescent (but not tomentose) with short but straight hairs (not curly as in subsp. Annona senegalensis oulotricha) to glabrescent. See notes under subsp. Annona senegalensis oulotricha and Le Thomas (1969c) for more details. The fruits are edible. Le Thomas (1969c p. 2) suggested that there exists a specimen of Thonning sent to Jussieu by Vahl in 1804 and present in P (under catalogue number 10779 from Herb. Jussieu) and that this would be the lectotype. However, we were not able to locate this specimen using the online scanned material. Specimens examined.
