Indumentum of simple hairs; old leafless branches glabrous, young foliate branches pubescent. Leaves: petiole 3-5 mm long, 2-3 mm in diameter, glabrous to pubescent, slightly grooved, blade inserted on top of the petiole; <b>blade 25-34 cm long, 4.5-9 cm wide, narrowly oblong to narrowly obovate</b>, apex acuminate, acumen 1-3 cm long, base rounded to subcordate, coriaceous, below sparsely pubescent when young, glabrous when old, above glabrous when young and old; midrib sunken or flat, above glabrous when young and old, below pubescent when young, glabrous when old; secondary veins 11 to 20 pairs per side, glabrous above; tertiary venation reticulate. Individuals unisexual, monoecious, <b>inflorescences cauliflorous</b>. Flowers with 6 perianth parts in 2 whorls, <b>long conical in bud</b>, 1 to 2 per inflorescence, male and female inflorescences similar, but with a tendency of female flowers being located towards the base of the trunk; pedicel 3-8 mm long, ca. 1 mm in diameter, pubescent; in fruit 4-11 mm long, 2 mm in diameter, pubescent; bracts 2 to 3, all basal or towards the lower half of pedicel, 1-2 mm long, 1-2 mm wide; sepals 2, valvate, free, 3-4 mm long, 2 mm wide, triangular, apex attenuate, base truncate, brown, densely pubescent outside, glabrous inside, margins flat; petals free, 4, 25-45 mm long, 4-8 mm wide, <b>linear</b>, apex attenuate, base truncate, <b>wine-brown to dark red</b>, margins flat, pubescent outside, <b>glabrous and highly verrucose inside</b>; male flowers: stamens 400 to 600, in 15 to 20 rows, ca. 1 mm long, broad; connective reduced or absent, glabrous, cream; staminodes absent; female flowers: carpels free, 24 to 40, ovary 2-3 mm long, 1-1.5 wide, stigma coiled, densely pubescent. Monocarps stipitate, stipes 3-6 mm long, ca. 2 mm in diameter; monocarps 4 to 6, 25-50 mm long, 10-20 mm in diameter, cylindrical, apex rounded, puberulent to glabrous, verrucose, wrinkled, bright red when ripe; seeds 6 to 16 per monocarp, 17-22 mm long, 10-12 mm in diameter, ellipsoid; aril absent. Distribution. From eastern Nigeria to northern Cameroon; in Cameroon known from South and South-West regions. Habitat. A common species when present; in lowland primary or old secondary rain forests. Altitude 50-800 m a.s.l. Local and common names known in Cameroon. None recorded. IUCN conservation status. Least Concern (LC) (Cosiaux et al. 2019a w). Uses in Cameroon. None reported. Notes. Vegetatively, <i>Uvariopsis bakeriana</i> is close to <i>U. citrata</i>, <i>U. korupensis</i> and <i>U. submontana</i>, having generally large leaves (largest leaves&gt; 31 cm) with a rounded to (sub)cordate base. When in flower, <i>U. bakeriana</i> is easily distinguished from other species by its linear to very narrowly elliptic petals (forming a long conical flower bud) which are free at base and deep red in color (when fresh).
