Scolopia madagascariensis (PROTA)
Introduction |
Scolopia madagascariensis Sleumer
- Protologue: Repert. Spec. Nov. Regni Veg. 45: 14 (1938).
- Family: Flacourtiaceae (APG: Salicaceae)
Origin and geographic distribution
Scolopia madagascariensis is endemic to Madagascar, where is widespread along the eastern coast.
Uses
The wood, known as ‘menavahatra’ in Madagascar, is used for heavy construction, heavy flooring, joinery, panelling, mine props, vehicle bodies and railway sleepers, and also as firewood. The fruit is eaten. A tea made from the leaves is drunk against fever.
Properties
A sample of Scolopia wood from Madagascar, possibly Scolopia madagascariensis, has been tested. The heartwood is greyish to pale brown or slightly reddish, and distinctly demarcated from the yellowish white, 3–5 cm wide sapwood. The grain is straight to interlocked, texture rather coarse. The wood is heavy, with a density of 890–950 kg/m³ at 12% moisture content, and hard. It should be air dried slowly and with care to avoid serious degrade. The rates of shrinkage are moderate to high, from green to oven dry 5.5% radial and 11.2% tangential. A board of 2.5 cm thick air dried in 3–4 months with little distortion. Once dry, the wood is rather unstable in service. At 12% moisture content, the modulus of rupture is 189 N/mm², modulus of elasticity 15,200 N/mm², compression parallel to grain 77 N/mm², shear 21 N/mm² and Chalais-Meudon side hardness 6.8–7.6. The wood is fairly easy to work and takes a good finish. It is moderately durable and rather difficult to treat with preservatives.
Description
Evergreen, small to medium-sized tree up to 25 m tall, glabrous except for the inflorescence; bole up to 60(–100) cm in diameter; bark surface nearly smooth to scaly, greyish, with longitudinal rows of lenticels, inner bark reddish. Leaves arranged spirally, simple and entire; stipules minute, caducous; petiole 0.5–1 cm long; blade elliptical to oblong-elliptical or obovate, 6–11(–14) cm × 2.5–7(–9) cm, base broadly cuneate, apex acuminate, leathery, pinnately veined with many pairs of lateral veins and with 2 distinct basal lateral veins ascending towards the upper part of the leaf. Inflorescence an axillary raceme 1–2.5(–5) cm long, minutely hairy. Flowers bisexual, regular, 4–5-merous, whitish; pedicel 3–5 mm long; sepals ovate, 1.5–2 mm long; petals similar but slightly narrower than sepals; disk small, lobed; stamens 80–100; ovary superior, glabrous, 1-celled, style 3–4 mm long, slender, stigma obscurely 3–4-lobed. Fruit a globose to ellipsoid berry 1–1.5 cm in diameter, fleshy, 2–5-seeded. Seeds rounded, flattened, c. 2 mm in diameter. Seedling with epigeal germination.
Other botanical information
Scolopia madagascariensis trees grow slowly. In an enrichment planting, trees reached on average only 1 m tall 7 years after planting. Young trees tolerate some shade. The flowering period is usually April–June.
Scolopia comprises about 40 species and occurs from tropical Africa through tropical Asia to Australia. In mainland Africa about 6 species are found, 14 in Madagascar and 1 in the Mascarene islands. The wood of some other Scolopia spp. of the rainforest of eastern Madagascar is used for similar purposes as that of Scolopia madagascariensis.
Scolopia erythrocarpa
Scolopia erythrocarpa H.Perrier is a large shrub or small tree up to 8(–15) m tall. Its wood is used for similar purposes as that of Scolopia madagascariensis. In traditional medicine its leaves are applied as a poultice against rheumatic pain. Its fruits are eaten.
Scolopia hazomby
Scolopia hazomby H.Perrier is a small to medium-sized tree up to 20 m tall. Its wood is used for similar purposes as that of Scolopia madagascariensis. It has edible fruits.
Scolopia orientalis
Scolopia orientalis Sleumer is a small tree up to 15 m tall. Its wood is used for similar purposes as that of Scolopia madagascariensis.
Scolopia heterophylla
Scolopia heterophylla (Lam.) Sleumer is a shrub or small tree up to 7(–15) m tall, endemic to Mauritius, Réunion and Rodrigues. Its wood has been used for similar purposes as that of Scolopia madagascariensis in Madagascar. In Mauritius and Réunion leaf decoctions are taken against fever. However, Scolopia heterophylla has become rare because of forest degradation.
Ecology
Scolopia madagascariensis occurs in rainforest up to 1000(–1900) m altitude, in regions with about 2500 mm annual rainfall, usually on lateritic soils.
Management
There are 25,000–33,000 seeds per kg. Fresh seeds have a high germination rate, up to 95% in 3.5–15 weeks. They can be stored in a cool locality, but lose their germination capacity after 4–6 months.
Genetic resources
Scolopia madagascariensis is widespread and although its habitat is shrinking, it is not yet listed as threatened by genetic erosion.
Prospects
The wood of Scolopia madagascariensis and some other Scolopia spp. from Madagascar is likely to remain of local importance. However, trees seem to grow too slowly to have good prospects for timber plantations.
