Description
Lectotype (designated here): — ZIMBABWE, valley of the Hanyani River, 17 May 1909; Allen 734 (lecto-: K! [barcode K000240353]).
Tree 3–10(–20) m high; branchlets almost glabrous. Leaf: petiole 4–15 mm long, slightly pubescent; blade ovate-elliptic or elliptic to oblong or obovate-oblong, 4–9.5 × 1.5–5 cm, rounded to slightly cordate at the base, obtuse to truncate at the apex; lateral nerves in 7–11 pairs, progressively fading out well before reaching the margin; upper surface finely reticulate, with reticulum generally orange-lepidote, shiny, glabrous, often yellowish green on drying; lower surface concolorous, smooth, glabrous; midrib and lateral nerves slightly depressed above and prominent beneath, reticulation scarcely prominent, orange-coloured. Inflorescences axillary, 2–4 cm long (shorter in the specimen from D.R. Congo), slender, lax (congested in the specimen from D.R. Congo), 4–10-flowered, brownish, glabrescent, on a slender peduncle 1–1.5 cm long (sessile in the in the specimen from D.R. Congo). Flower: pedicel ca. 5 mm long; sepals ca. 3 mm long, densely cottony-tomentose; petals ca. 7.5 mm long, brownish white, shortly greyish- or yellowish-sericeoustomentose; stamens with anthers produced into a very short mucro. Fruit subglobose, 7–12 mm in diameter, sericeous, rounded or slightly conical at the apex; wings 2–3 × 1–1.5 cm, yellow or brownish, elliptic to obovate (description based on Duvigneaud (1961)).
Distribution in D.R. Congo: —A single collection in D.R. Congo, ca. 500 km N of the nearest localities in Zambia.
Distribution elsewhere: — Botswana, Zambia, Zimbabwe.
Habitat and ecology: —Miombo woodlands and wooded savannahs.
Additional specimen examined:—D.R. CONGO. Upper Katanga: Upemba, Munoi, bifurcation Lupiala, 890 m, savane arbustive, 3 June 1948, de Witte 3902 (BR!).
Discussion:— The cited collection is the only one from D.R. Congo that can be tentatively ascribed to M. glaber. However, it is atypical in having flowers in dense subsessile cymes. It may represent a distinct taxon, but more material is necessary. See also note under M. africanus.
Allen 734 is here chosen as the lectotype, because the other syntype (Baines s.n. (K!)) is mounted on a sheet with a mixture of several gatherings.
