Liana, 2-20 m tall, d.b.h. unknown. Indumentum of <b>minute stellate or simple hairs</b>; old leafless branches pubescent to glabrescent, young foliate branches densely pubescent. Leaves: petiole 2-3 mm long, ca. 1 mm in diameter, pubescent, grooved, blade inserted on top of the petiole; blade 6-23 cm long, 2.5-10 cm wide, elliptic to oblong, apex acuminate to obtuse, acumen 1-1.2 cm long, base rounded to subcordate, papyraceous to coriaceous, <b>below densely pubescent</b> covered with minute stipitate stellate hairs when young and old, <b>above pubescent with short simple scabrid hairs (or glabrous besides veins)</b> when young and old; midrib sunken or flat, above densely pubescent when young and old, below densely pubescent when young and old; <b>secondary veins 9 to 16</b> pairs, densely pubescent above; <b>tertiary venation percurrent</b>. Individuals bisexual; inflorescences ramiflorous on young foliate branches, leaf opposed or extra axillary. Flowers with 9 perianth parts in 3 whorls, 1 to 2 per inflorescence; pedicel 10-25 mm long, 1-2 mm in diameter, densely pubescent to tomentose; in fruit 20-40 mm long, 6 mm in diameter, pubescent; bracts 2, soon falling, one basal and one towards the upper half of pedicel, basal bract 10-15 mm long, 7-10 mm wide; upper bract not seen; sepals 3, valvate, basally fused, 15-20 mm long, 7-13 mm wide, ovate, apex acute to obtuse, base truncate, yellow brown, densely pubescent outside, pubescent inside, margins flat; petals free, sub equal; outer petals 3, 18-30 mm long, 13-20 mm wide, elliptic to ovate, apex attenuate, base truncate, yellow-brown, margins flat, densely pubescent outside, pubescent inside; inner petals 3, imbricate, 15-25 mm long, 12-19 mm wide, ovate, apex obtuse, base truncate, yellow brown, margins flat, pubescent outside, sparsely pubescent to glabrous inside; stamens 180 to 200, in 9 to 10 rows, ovary 1-2 mm long, linear; connective discoid, glabrous, cream to yellow; staminodes absent; carpels free, 45 to 70, ca. 3 mm long, stigma coiled, pubescent. <b>Monocarps sessile</b>, 20 to 35 <b>tightly packed together</b>, 15-20 mm long, 10-13 mm in diameter, pyramidal or four-sided, apex rounded to shortly apiculate, <b>tomentose, verrucose to shortly echinate</b>, not ribbed or 1-ribbed, green when ripe; seeds 4 to 6 per monocarp, 8-12 mm long, 4-6 mm in diameter, flattened; aril absent. Distribution. A widespread species in west and central Africa, in Liberia and Nigeria and in Cameroon, Gabon and Equatorial Guinea to the Democratic Republic of the Congo and Angola; in Cameroon known in the Central, East, Littoral, South and South-West regions. Habitat. A fairly common species in Cameroon; in lowland secondary or primary rain forests, gallery forests, growing along forest openings. Altitude 0-800 m a.s.l. Local and common names known in Cameroon. None recorded. IUCN conservation status. Not evaluated. Uses in Cameroon. None reported. Notes. <i>Uvaria scabrida</i> is distinguished by its leaves covered below with uniform stellate hairs, and above with minute scabrid simple hairs, as well as by its sessile, densely tomentose monocarps. Together with <i>U. obanensis</i>, it is the only species of <i>Uvaria</i> in Cameroon with sessile monocarps. Vegetatively, it resembles <i>U. osmantha</i>, but the latter has shorter (10-15 mm long) and stipitate monocarps, and its leaf blades are strongly discolorous with their lower surface completely obscured by the stellate indumentum, while in <i>U. scabrida</i> it is visible between the hairs. A few collections from Cameroon (<i>Bos 3164, 3353, 5011, 5508</i>) and Gabon (<i>Wieringa 4387</i>) have glabrous leaves above apart from the veins, and therefore are not scabrid. Nevertheless, they have the characteristic monocarps and thus match <i>U. scabrida</i>, possibly being a variety (Lachenaud, pers. comm.).
