Dasylepis integra Warb. ex Engl.

distribution in Africa (wild)

Protologue: Abh. Preuss. Akad. Wiss.: 44 (1894).

Family: Flacourtiaceae (APG: Achariaceae)

Synonyms

• Dasylepis leptophylla Gilg (1908).

Origin and geographic distribution

Dasylepis integra is restricted to south-eastern Kenya and north-eastern Tanzania.

Uses

The wood is locally used for furniture, utensils, clubs and tool handles, and also as firewood.

Properties

The wood is moderately hard.

Description

• Evergreen shrub or small tree up to 15(–35) m tall; bole slender; bark surface smooth, becoming flaky, grey-brown, inner bark orange-red.
• Leaves alternate, simple; stipules early caducous; petiole 5–7(–10) mm long; blade elliptical to lanceolate or oblong, 8–16 cm × 2.5–6 cm, cuneate to obtuse at base, short-acuminate at apex, margins entire to remotely toothed, papery to thin-leathery, glabrous, pinnately veined with 5–9 pairs of looping lateral veins.
• Inflorescence a drooping axillary raceme up to 12 cm long, glabrous, laxly flowered.
• Flowers bisexual or male, regular; pedicel slender, 5–8(–20) mm long; sepals 3–4, slightly fused at base, rounded to elliptical, c. 5 mm long, pinkish-reddish, glabrous; petals 7–8, similar to sepals but slightly longer, more whitish and with basal hairy appendage inside; stamens 15–20, c. 5 mm long; ovary superior, glabrous, 1-celled, style very short, with 3 short branches.
• Fruit a globose capsule 1.5–2 cm in diameter, short-pointed, with 3–4 longitudinal grooves, glabrous, pale purple, tardily dehiscent with 3 valves, 1–2(–5)-seeded.
• Seeds ovoid-angular, 8–9 mm long, glabrous.

Other botanical information

Flushes of young leaves are reddish.

Dasylepis comprises 6 species and is related to Erythrospermum, Rawsonia and Scottellia. Dasylepis integra resembles Dasylepis racemosa Oliv., which is a small to medium-sized tree up to 20 m tall with bole up to 45 cm in diameter with a much larger area of distribution, from Guinea east to western Uganda and south to Gabon and DR Congo. Although uses of Dasylepis racemosa have not been recorded, its wood is possibly locally used for similar purposes as that of Dasylepis integra.

Ecology

Dasylepis integra usually occurs in the understorey of moist forest at 900–2250 m altitude. It is locally co-dominant.

Genetic resources

Dasylepis integra has a restricted area of distribution, which is severely fragmented. Therefore, it has been included in the IUCN Red List as vulnerable.

Prospects

The wood of Dasylepis integra will remain of limited importance for local applications. The small size of the bole makes that it has no prospects for the international timber market, and focus should be primarily on its protection.
