Dalbergia baronii [1] is a species of flowering plant in the legume family Fabaceae. It is endemic to Madagascar.[2] It is named after the English missionary and botanist Rev. Richard Baron.

Description

Vegetative characters

Dalbergia baronii is a shrub to large tree. The leaves are imparipinnate, 3–7.5 cm long, and have a hairy rachis. The 19–25 alternate leaflets are 0.5–2 cm long, mostly glabrous and glossy above, and with dense and long hairs beneath.[2]

Generative characters

It forms axillary inflorescences that are paniculate and distinctively shorter than the subtending leaves. The flowers are white, 4–5 mm long, and have a violin-shaped standard petal and pubescent gynoecium. The fruits usually contain one seed (rarely up to three seeds). The pericarp is "indistinctly veined, slightly thickened, corky and fissured over the seed".[2]

Similar species

Habitat and distribution

Dalbergia baronii inhabits evergreen lowland forests, marshes and mangrove stands along the East coast of Madagascar.[2] It occurs from sea level up to 150 m, rarely up to an elevation of 600 m.[2]

Uses

It produces a durable, black-striped heartwood[3] that is locally used for cabinet making, furniture and marquetry.[2] It was internationally traded, notably to produce guitar bodies and fingerboards,[3] amongst others.

Conservation status

The IUCN Red List lists Dalbergia baronii as vulnerable.[4] Its natural stands have drastically declined in response to both habitat loss and selective logging.[5] The natural habitat of Dalbergia baronii is among the most threatened Malagasy habitats.[6]

Due to overexploitation and the risk of confusion with similar species, Dalbergia baronii and other Dalbergia species from Madagascar were listed in CITES Appendix II[7] in 2013, currently with a zero export quota.[8]
