Definition
Dalbergia velutina is a species of flowering plant in the legume family Fabaceae. It is a tree that produces hardwood timber and is native to parts of Southeast Asia.
Overview
The species occurs in tropical forest habitats of the Malay Peninsula, Borneo, Sumatra, and the Philippines. It typically grows at low to medium elevations, often in primary or secondary rainforest. Like other members of the genus Dalbergia, it is valued for its dense, durable wood, which is used locally for furniture, flooring, and small woodworking projects. Conservation status has not been uniformly assessed across its range; however, habitat loss due to logging and land‑use change may affect local populations.
Etymology / Origin
The generic name Dalbergia honors Swedish botanist and diplomat Anders Gustaf Dalberg (1743–1797). The specific epithet velutina derives from the Latin velutinus, meaning “velvety,” a reference to the texture of the leaf surface or young shoots, which are reported to have a fine, soft indumentum.
Characteristics
| Feature | Description |
|---|---|
| Growth form | Evergreen tree, commonly reaching 15–30 m in height, with a straight bole and a rounded canopy. |
| Leaves | Pinnately compound, usually with 5–9 leaflets; leaflets are oblong‑elliptic, leathery, and exhibit a velvety (pubescent) underside. |
| Flowers | Small, fragrant, white to pale yellow; arranged in axillary or terminal racemes. Flowers are typical of Fabaceae, with a standard, wings, and keel. |
| Fruit | Leguminous pods, 5–10 cm long, containing 1–2 seeds; pods mature to a brown, slightly curved form and split open along both sutures when ripe. |
| Wood | Heavy, dense, and fine‑grained; heartwood ranges from pale yellowish to brown, often streaked. The wood is resistant to decay and is sought after for high‑quality timber. |
| Ecology | As a legume, the species is capable of nitrogen fixation through symbiosis with root‑nodule bacteria, contributing to soil fertility in forest ecosystems. |
