Combretaceae, Hutchinson and Dalziel. Flora of West Tropical Africa 1:1. 1954

Morphology General Habit
Savannah tree, to 25 ft. high
Morphology Reproductive morphology Flowers
Petals and filaments cream or yellow
Morphology Reproductive morphology Fruits
Young fruits red and very glutinous, becoming pale brown.
Note
At least four forms occur in our area, but they appear to be connected by intermediates and cannot be separated satisfactorily, even as varieties. They are: (A) leaves pubescent, broadly elliptic, broadest at or slightly above the middle, obtuse at apex, petiole relatively short, flowers densely hairy (B) leaves glabrous, broadly lanceolate, broadest below the middle, acute or acuminate at apex, margin markedly undulate, petiole relatively long; flowers densely hairy (C) leaves as in B, but flowers sparsely pubescent (D) leaves as in A, but glabrous except for conspicuous tufts in tlie axils of the main lateral nerves, flowers sparsely pubescent.

Morphology General Habit
Deciduous shrub or small tree up to c. 10(12) m. high; crown obovoid or rounded; bark creamy-brown or grey-brown, vertically cracked, scaly, exuding gum.
Morphology Leaves
Leaves opposite or very frequently 3–1-verticillate; lamina up to 20 x 9 cm., usually glutinous especially when young, ovate or ovate-elliptic, tomentose to nearly glabrous (except for scales) and lepidote (often rather inconspicuously), apex acute to rounded, base usually cuneate; lateral nerves 7–10 pairs, rather prominent beneath; petiole up to 1·5 cm. long or sometimes very short (leaf subsessile), leaving a prominent circular scar.
Morphology Reproductive morphology Inflorescences
Inflorescences of axillary spikes up to 7 cm. long, sometimes branched, often appearing before the leaves in axils of fallen leaves; rhachis usually densely pubescent; bracts 1·5 mm. long, deciduous.
Morphology Reproductive morphology Flowers
Flowers sessile, greenish or dirty-white or yellow.
Morphology Reproductive morphology Flowers Receptacle
Lower receptacle 1·5–3 mm. long, usually tomentose; upper receptacle 2–3 x 2–3 mm., infundibuliform to broadly campanulate at the base and cupuliform at the apex, pubescent to tomentose.
Morphology Reproductive morphology Flowers Calyx
Sepals 1 x 1·5 mm., broadly triangular.
Morphology Reproductive morphology Flowers Corolla
Petals 2–3x 1–1·5 mm., cuneate or spathulate to obovate, glabrous.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamen-filaments 5–6 mm. long, inserted at the margin of the disk; anthers 0·8–1 mm. long.
Morphology Reproductive morphology Flowers Disc
Disk with a pilose free margin.
Morphology Reproductive morphology Fruits
Fruit brown or reddish-yellow, 2·5–3·5 x 2·5–3 cm., glutinous, subcircular to elliptic in outline, rather inconspicuously lepidote otherwise glabrous, apical peg up to 3 mm. long, wings up to 12 mm. broad, stipe up to 5(7) mm. long.
Morphology Reproductive morphology Seeds Cotyledons
Cotyledons 2, 2 x 3 cm., transversely elliptic, arising as in the sectional description.
Morphology General Scales
Scales as for the section.

Combretaceae, G. E. Wickens. Flora of Tropical East Africa. 1973

Morphology General Habit
Small tree up to 10(–12) m. high; bark grey, reticulately fissured; branches peeling to give dark reddish brown colour; branchlets glabrous, glutinous or pubescent.
Morphology Leaves
Leaves opposite or 3(–4)-verticillate; lamina papyraceous to coriaceous, narrowly to broadly ovate-elliptic to ovate, up to 15(–20) cm. long and 9(–11) cm. wide, apex acute or obtuse, base usually cuneate, usually glutinous, especially so when young, rarely tomentose in East Africa to nearly glabrous (except for the scales), sparsely lepidote above, scales almost contiguous beneath but often very difficult to see due to the glutinous exudation; lateral nerves 7–10(–13) pairs, usually prominent on both surfaces, reticulation slightly raised beneath; petiole up to 1.5 cm. long, leaves sometimes subsessile, leaving a prominent circular scar when fallen, especially so on the swollen nodes of the older wood.
Morphology Reproductive morphology Inflorescences
Inflorescences axillary, either single simple spikes or clusters of such spikes borne on very much reduced axillary shoots or single axillary spikes on elongated shoots (20 cm.) that are leafless at flowering thus giving the appearance of a branched inflorescence, both short and elongated shoots densely yellow-brown pubescent.
Morphology Reproductive morphology Flowers
Flowers (fig. 3/11, p. 14) greenish yellow to white becoming yellow, fragrant.
Morphology Reproductive morphology Flowers Receptacle
Lower receptacle usually tomentose; upper receptacle infundibuliform to broadly campanulate at the base and cupuliform at the apex, 2–3 mm. long, 2–3 mm. in diameter, pubescent to tomentose.
Morphology Reproductive morphology Flowers Calyx
Sepals broadly triangular.
Morphology Reproductive morphology Flowers Corolla
Petals cuneate or spathulate to obovate, 2–3 mm. long, 1–1.5 mm. wide, glabrous.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamen-filaments 5–6 mm. long, inserted at the margin of the disk; anthers 0.8–1 mm. long.
Morphology Reproductive morphology Flowers Disc
Disk with pilose free margin.
Morphology Reproductive morphology Flowers Gynoecium Style
Style 3–4 mm. long.
Morphology Reproductive morphology Fruits
Fruit (fig. 4/11, p. 15) subcircular to elliptic in outline, 2.5–3.5 cm. long, 2.5–3 cm. wide, yellow-brown to brown, glutinous, rather inconspicuously lepidote, otherwise glabrous; apical peg up to 3 mm. long; wings up to 12 mm. broad; stipe up to 5(–7) mm. long.
Morphology Reproductive morphology Seeds Germination
Cotyledons 2, arising below soil-level and borne above ground on a long stalk formed by the connate petioles.
Morphology General Scales
Scales (fig. 2/11, p. 13) 50–65 μ in diameter.
Habitat
Common in deciduous woodland and wooded grassland, often associated with seasonally waterlogged clay soils, but sometimes on shallow stony soils; 50–1700 m.
