Names
PERICOPSIS angolensis (Bak.) van Meeuwen [family LEGUMINOSAE-PAPILIONOIDEAE], in B.J.B.B. 32: 216 (1962); Hillcoat in C.F.A. 3: 381 (1966). Type: Angola, Huila, Humpata–Mumpula, Welwitsch 615 (BM, K, iso.!)
Information
Tree up to 17 m. tall; bark smooth, pale, flaking off when old in thin scales. Leaves with 7–10(13) leaflets arranged alternately or rarely in opposite pairs; petiole, rhachis and petiolules rusty-brown or rarely greyish puberulous to tomentose, sometimes ± glabrescent; stipels usually inconspicuous and caducous, 1–2(–4) mm. long; leaflets ovate to elliptic or the distal ones obovate, (2–)3.5–6.5(–9.5) cm. long, (l.5–)2–3.5(–4) cm. wide, rounded to cuneate and ± asymmetrical at the base, rounded to emarginate at the apex, with varying development of indumentum (see notes below). Inflorescence (including calyces) usually rusty-brown or rarely greyish tomentose. Calyx (excluding receptacle) 7–10(–11) mm. long. Petals white, greenish-white or violet, with dark purple veins; standard 13–15 mm. long; wings slightly longer. Fruits variable in size and shape, 7–24 cm. long, (2–)2.5–3.5(–4) cm. wide, glabrous, or (not in East Africa) pubescent.
Notes
VARIATION (of species as a whole). The pubescence of the leaves varies considerably. Plants west of a line from Lakes Nyasa to Victoria are generally more hairy, with a velvety to floccose tomentum ± covering the petiole, leaf-rhachis and extending on to the leaflets at least along the midrib beneath. The surface of the leaflets beneath may be glabrous, but is generally sparsely pubescent to tomentose especially on leaves produced with the flowers (glabrescent leaflets seem to be more usual later in the season); pubescence on the upper surface of the leaflets is common only on leaves of flowering specimens from north of the Central Railway. Plants east of the line from Nyasa to Victoria tend to have a less dense indumentum and some from the eastern edge of the range have the petiole, rhachis and leaflet-midrib completely glabrous. Such glabrescent forms occur sporadically throughout the range of the species and are distinguished only as a form.
