Tree, up to 5 m tall, d.b.h. unknown; stilt roots and buttresses absent. Old branches glabrous to pubescent, <b>young branches rusty-pubescent</b>, with sparser erect hairs 1.5-2 mm long mixed with denser erect hairs 0.2-0.4 mm long. Leaves: petiole 3-5 mm long, ca. 1 mm wide, rusty-pubescent, grooved, blade inserted on the side of the petiole; blade 9.2-12.5 cm long, 3-4.2 cm wide, lanceolate-oblong to elliptic, rarely oblanceolate, <b>apex acuminate, acumen 0.9-1.7 cm long</b>, base cuneate to rounded, papyraceous, below pubescent when young, densely pubescent to pubescent when old, above glabrous when young and old, concolorous to discolorous; midrib sunken or flat, above densely pubescent when young, pubescent when old, below pubescent when young and old; secondary veins 11 to 15 pairs, glabrous, above; tertiary venation reticulate. Individuals bisexual; inflorescences ramiflorous on young foliate branches, axillary, peduncle absent. Flowers with 9 perianth parts in 3 whorls, 1 per inflorescence; pedicel 3-6 mm long, 1-2 mm in diameter, <b>rusty-pubescent</b>; in fruit 3-6 mm long, 1-2 mm in diameter, glabrous; bracts 2 to 3, evenly spaced, 3-4 mm long, 2-3 mm wide; sepals 3, valvate, basally fused, 4-6 mm long, 3-4 mm wide, triangular to ovate, apex acute to acuminate, base truncate, densely rusty-pubescent outside, glabrous inside; petals free, subequal; outer petals 3, 32-38 mm long, 3.1-3.3 mm wide at base, linear, apex acute to obtuse, base broad and concave, color unknown, sericeous outside, pubescent and glabrous towards the base inside; inner petals 3, valvate, 16-33 mm long, 2.1-3.2 mm wide at base, linear, apex acute, base truncate, color unknown, pubescent, base glabrous outside, pubescent and glabrous towards the base inside; stamens ca. 140, in rows, 1-2 mm long, oblong; connective apex shield-like, glabrous; carpels ca. 8, ovary 1 mm long, stigmas connivent, linear, bent at midpoint, 2.5-3 mm long, glabrous. Monocarps (only immature ones seen) sessile; monocarps ca. 8, 10-30 mm long, 9-25 mm wide, apex with a small curved beak, sparsely pubescent; seeds unknown. Distribution. Eastern Nigeria and Cameroon; in Cameroon known from South and South-West regions. Habitat. A rare species, in Cameroon known from three collections; in gallery forests near rivers (<i>Bos 4650</i>) or lowland rain forests. Altitude: 0-50 m a.s.l. Local and common names known in Cameroon. None recorded. IUCN conservation status. Data Deficient (DD) (Cosiaux et al. 2019b g). Uses in Cameroon. None reported. Notes. <i>Xylopia talbotii</i> is readily distinguished by the striking and persistent rusty pubescence of the twigs, petioles, pedicels, and sepals, and the long-acuminate leaves. It is similar in flower characteristics to the more widespread <i>X. thomsonii</i>.
