Tree, 8-30 m tall, d.b.h. 12-15 cm; stilt roots or buttresses absent. Indumentum of simple hairs; old leafless branches glabrous, young foliate branches pubescent. Leaves: petiole 2-4 mm long, 1-2 mm in diameter, pubescent, cylindrical, blade inserted on top of the petiole; blade 9.5-26 cm long, 3.5-10 cm wide, obovate, apex acuminate, acumen 0.5-1.8 cm long, base obtuse to acute, papyraceous, below sparsely pubescent when young and old, above glabrous when young and old, discolorous, whitish below; midrib impressed, above glabrous when young and old, below pubescent to tomentose when young, pubescent to tomentose when old; secondary veins 17 to 33 pairs, glabrous above; tertiary venation percurrent. Individuals bisexual; inflorescence cauliflorous, peduncle like base 15-65 mm long, axial internodes 5-35 mm long, compact to lax, <b>sympodial rachis 6-38 mm long.</b> Flowers with 9 perianth parts in 3 whorls, <b>(1) 2 to 7 per inflorescence</b>; pedicel ca. 7 mm long, ca. 2 mm in diameter, pubescent; in fruit 10-15 mm long, ca. 4 mm in diameter, tomentose; basal bract ca. 8 mm long, ca. 5 mm wide; upper bract ca. 4 mm long, ca. 2 mm wide; sepals 3, valvate, free, ca. 12 mm long, ca. 4 mm wide, ovate, apex acute, base truncate, brown, pubescent outside, glabrous inside, margins flat; petals free, outer petals shorter than inner; outer petals 3, ca. 15 mm long, ca. 4 mm wide, ovate, apex acute, base truncate, margins flat, tomentose outside, glabrous inside; inner petals 3, valvate, 38-45 mm long, 10-12 mm wide, ovate, apex acute, base truncate; stamens numerous, in 6 to 8 rows, ca. 1 mm long, broad; connective discoid, glabrous, red; staminodes absent; carpels free, 4 to 7, ovary ca. 2 mm long, stigma globose, pubescent. Monocarps sessile, 3 to 4, 20-35 mm long, 10-20 mm in diameter, <b>ellipsoid to ovoid</b>, apex rounded, <b>sparsely pubescent to glabrous, smooth, bumpy when dry, pink reddish when ripe</b>; seeds 4 to 5 per monocarp, ca. 10 mm long, ca. 6 mm in diameter, ellipsoid; aril absent. Distribution. endemic to Cameroon, known from the Littoral and South-West regions. Habitat. A fairly uncommon species; in the understory of submontane and lowland rain forests. Altitude 200-900 m a.s.l. Local and common names known in Cameroon. Niock (Dial. Yaoundé, <i>Fleury F. 33134</i>). IUCN conservation status. Vulnerable B1ab(iii)+2ab(iii) (Cosiaux et al. 2019a i). Uses in Cameroon. None reported. Notes. <i>Piptostigma goslineanum</i> closely resembles <i>P. glabrescens</i> by the shape and the size of their leaf blades, but the inflorescences of <i>P. goslineanum</i> are generally shorter than 12 cm long with 2-7 flowers, while those of <i>P. glabrescens</i> can reach up to 55 cm long with 10-28 flowers. In addition, the monocarps of <i>P. goslineanum</i> are smooth and ovoid to ellipsoid in shape, while those of <i>P. glabrescens</i> are puncticulate and oblong in shape. In the check list of the plants of Mt. Kupe and Bakossi (Cheek et al. 2004), collections cited under <i>Piptostigma</i> sp. 1 belong to <i>P. goslineanum</i>.
