Maesobotrya floribunda Benth.
- Protologue: Hook.f., Icon. pl. 13: t. 1296 (1879).
- Family: Euphorbiaceae (APG: Phyllanthaceae)
Origin and geographic distribution
Maesobotrya floribunda occurs from Cameroon and the Central African Republic south to DR Congo and Zambia.
Uses
In DR Congo the leaves are rubbed on the skin to treat prickly heat.
In Gabon the young leaves provide a sour potherb. In DR Congo the wood is used to make house posts and kitchen utensils. Birds will not eat the fruits.
Properties
The picrotoxane sesquiterpenoid picrotoximaesin was isolated from a methanol extract of the seeds.
Description
Dioecious shrub or small tree up to 8(–12) m tall, with drooping branches; bark greyish brown, longitudinally grooved; twigs angular, yellowish short-hairy. Leaves alternate, simple; stipules linear-lanceolate, 2.5–4 mm long, short-hairy, soon falling; petiole up to 7 cm long; blade elliptical to oblong-oblanceolate, 4–18 cm × 2.5–7 cm, base cuneate to rounded, apex shortly acuminate, distantly shallowly glandular-toothed in upper part, glabrous or short-hairy. Inflorescence a slender axillary or cauliflorous raceme up to 10 cm long, solitary or up to 4 together. Flowers unisexual, 5-merous, petals absent; male flowers with pedicel 1–1.5 mm long, jointed, calyx lobes triangular, c. 1 mm long, creamy yellow, stamens c. 1.5 mm long, free, disk glands fleshy; female flowers with pedicel 1–2 mm long, calyx lobes ovate, c. 1 mm long, greenish cream, disk c. 1.5 mm in diameter, ovary superior, ovoid-ellipsoid, c. 1.5 mm long, densely short-hairy, 2-celled, styles 2, fused at base, c. 0.5 mm long, persistent, stigma papillose. Fruit an ellipsoid capsule 5–6 mm × 4.5–5 mm, late dehiscent, smooth, sparingly short-hairy, green to reddish or purplish, 1-seeded by abortion. Seed ellipsoid, c. 6 mm × 3.5 mm, purplish grey to bluish.
Other botanical information
Maesobotrya comprises 18 species, which all occur in tropical Africa. Several other Maesobotrya species are also used medicinally in the region.
Maesobotrya cordulata
In Congo a paste of pounded fruits of the Central African Maesobotrya cordulata J.Léonard is applied to treat psoriasis. Pulverized leaves are applied to wounds to heal them and are applied to scarifications to treat oedema.
Maesobotrya vermeulenii
In Congo a bark decoction of Maesobotrya vermeulenii (De Wild.) J.Léonard is drunk and taken in baths to treat leprosy.
Ecology
Maesobotrya floribunda occurs mainly in gallery forest, often in open, seasonally inundated localities, from sea-level up to 1000 m altitude. It mainly grows on sandy loam, enriched with clay or organic material.
Genetic resources
Maesobotrya floribunda is fairly common in its area of distribution and is therefore not likely to be threatened by genetic erosion.
Prospects
Maesobotrya floribunda is not much used medicinally, and will probably remain of local importance only.
