Democratic Republic of the Congo. Kasaï Central; Mukenge, <i>Pogge P. 622</i>, 18 Sep 1882: lectotype, designated by Le Thomas (1969b), p. 73: B[B 10 0153109]; isolectotype: K[K000198768]. Description. Liana, 15-18 m tall, d.b.h. 3-10 cm. Indumentum of <b>minute stellate or simple hairs</b>; old leafless branches sparsely pubescent, <b>young foliate branches tomentose</b>. Leaves: petiole 2-3 mm long, 1-2 mm in diameter, densely pubescent to tomentose, slightly grooved, blade inserted on top of the petiole; blade 8-19 cm long, 5-9 cm wide, obovate to elliptic, apex acuminate, acumen ca. 1 cm long, <b>base rounded to cordate</b>, papyraceous to membranaceous, <b>below rather densely pubescent with stipitate stellate</b> hairs when young and old, <b>above sparsely pubescent</b> with simple hairs (soft to touch) when young and old; midrib sunken or flat, above sparsely pubescent when young and old, below densely pubescent when young and old; <b>secondary veins 15 to 24</b> pairs, sparsely pubescent to glabrous above; <b>tertiary venation percurrent</b>. Individuals bisexual; inflorescences ramiflorous on young foliate branches, extra axillary. Flowers with 9 perianth parts in 3 whorls, 1 per inflorescence; pedicel 15-20 mm long, 1-2 mm in diameter, densely pubescent; in fruit 25-35 mm long, 2-3 mm in diameter, sparsely pubescent; bracts 2, one basal and one upper towards the lower half of pedicel, basal bract 2 mm long, 2 mm wide; upper bract 2-3 mm long, 3-5 mm wide; sepals 3, valvate, free, not covering in bud, 4-7 mm long, 5-8 mm wide, triangular to ovate, apex obtuse, base truncate, tomentose outside, pubescent inside, <b>margins reflexed</b>; petals free, sub equal; outer petals 3, 15-20 mm long, 12-15 mm wide, ovate, apex attenuate, base truncate, margins flat, tomentose outside, sparsely pubescent to glabrous inside; inner petals 3, imbricate, 15-20 mm long, 12-15 mm wide, ovate, apex attenuate, base truncate, margins flat, tomentose outside, sparsely pubescent to glabrous inside; stamens 150 to 200, in 8 to 10 rows, ca. 2 mm long, linear; connective discoid, sparsely pubescent; staminodes absent; carpels free, 15 to 20, ovary 3-4 mm long, stigma coiled, pubescent. Monocarps stipitate, <b>stipes 25-35 mm long</b>, 1-2 mm in diameter, <b>centrally inserted</b>; monocarps 30 to 35, 7-15 mm long, 7-15 mm in diameter, <b>globose</b>, apex apiculate, <b>densely to sparsely pubescent</b>, smooth, not ribbed, green when ripe; seeds not counted, ca. 7 mm long, 4-6 mm in diameter, ellipsoid; aril absent. Distribution. A central African species, known from Cameroon, Democratic Republic of the Congo, Gabon, Republic of the Congo, Central African Republic and Angola; in Cameroon known from the East region. Habitat. A fairly rare species (or at least rarely collected) in Cameroon; in lowland secondary or primary rain forests. Altitude 400-600 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 poggei</i> is distinguished by its leaves with numerous secondary veins (17 to 24), its lower leaf surface covered with an uniform indumentum of stellate hairs, and its globose monocarps with a long central stipes inserted centrally. This species only marginally reaches Cameroon (Harris 2002) where it is known from two collections (<i>Harris 6200</i>, <i>6528</i>) close to the Central African Republic border. The species is here regarded as monotypic; indeed, U. poggei var. anisotricha Le Thomas is raised to species rank, as <i>U. anisotricha</i> (see under that name). Specimens examined. <b>East Region</b>: Lobeke Reserve Terra firma forest 1 km east of Djangi Bai, 2.31°N, 15.76°E, <i>04 November 1998</i>, <i>Harris D.J.</i> 6200 (E); Lobeke Reserve 3-4 km north of Djembe road 5 km northeast of Bolu Bai, 2.21°N, 15.78°E, <i>24 November 1998</i>, <i>Harris D.J.</i> 6528 (E).
