Tree, 8-25 m tall, d.b.h. up to 30 cm; stilt roots or buttresses absent. Indumentum of simple hairs; old leafless branches glabrous, young foliate branches glabrous to pubescent. Leaves: petiole 3-8 mm long, 3-5 mm in diameter, glabrous to sparsely pubescent, grooved, blade inserted on top of the petiole; blade 16-38 cm long, 5-11 cm wide, oblong to obovate, apex attenuate to acuminate, acumen 2-3 cm long, base rounded to subcordate, papyraceous to subcoriaceous, below glabrous when young and old, above glabrous when young and old; midrib sunken or flat, above glabrous when young and old, below sparsely pubescent when young, glabrous when old; secondary veins 9 to 18 pairs per side, glabrous above; tertiary venation reticulate. Individuals unisexual, monoecious; <b>inflorescences cauliflorous, with hundreds (up to 500) of flowers packed at the base and then more sparsely distributed up to 6 m</b>. Flowers unisexual, monoecious, with 6 perianth parts in 2 whorls, <b>conical to pyramidal in bud</b>, 6 to 50 per inflorescence, male and female inflorescences dimorphic; male pedicel: 25-50 mm, ca. 1 mm in diameter, pubescent; female pedicel: 30-60 mm long, ca. 1 mm in diameter, pubescent; in fruit 25-90 mm long, 3-7 mm in diameter, glabrous; bracts 2 to 4, all basal, ca. 1 mm long, ca. 1 mm wide; male sepals 2, connate, splitting at maturity, 5-10 mm long, 6-12 mm wide, triangular, apex acute, base truncate, brown-red, pubescent outside, glabrous inside, margins flat; female sepals 2, connate, splitting at maturity, 6-8 mm long, 6-9 mm wide, broadly ovate, apex acute, base truncate, brown-red, pubescent outside, glabrous inside, margins flat; male petals, 4, <b>basally fused</b>, tube 4-9 mm long, 8-18 mm long, 5-8 mm wide, elliptic to narrowly elliptic, apex acute, base truncate, wine red, margins flat, tomentose outside, pubescent inside; female petals, 4, <b>basally fused</b>, tube 3-4 mm long, 15-17 mm long, 5-7 mm wide, elliptic to narrowly elliptic, apex acute, base truncate, wine red, margins flat, tomentose outside, pubescent inside; male flowers: stamens 700 to 1000, in 25 to 30 rows, 0.5-1 mm long, oblong; connective reduced or absent, glabrous, cream; staminodes absent; female flowers: carpels free, 60 to 100, ovary 15-24 mm long, stigma globose, pubescent. Monocarps shortly stipitate, stipes ca. 1 mm long, ca. 1 mm in diameter; monocarps 9 to 25, 17-80 mm long, 13-55 mm in diameter, ovoid to oblong, apex apiculate, sparsely pubescent to glabrous, smooth, slightly constricted over seeds in dried material, pale green turning dark yellow at maturity; seeds 6 to 12 per monocarp, 18-25 mm long, 8-13 mm in diameter, ellipsoid; aril absent. Distribution. endemic to Cameroon, known from the South, Littoral and South West regions. Habitat. A species restricted to submontane primary or old secondary rain forests. Altitude: (600) 900-1300 m a.s.l. Local and common names known in Cameroon. None recorded. IUCN conservation status. Endangered (EN) (Cheek 2014d). Uses in Cameroon. None reported. Notes. <i>Uvariopsis submontana</i> is distinguished by the combination of conical flower buds and basally fused 4 petals, and the trunk base completely covered with hunders of flowers. It is very close to <i>U. korupensis</i>, but differs by its smaller leaves, longer sepals, and submontane habitat (<i>U. korupensis</i> being found in the lowlands, generally below 700 m).
