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. [3]

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". [3]

Habitat and distribution

Dalbergia baronii inhabits evergreen lowland forests, marshes and mangrove stands along the East coast of Madagascar. [3] It occurs from sea level up to 150 m, rarely up to an elevation of 600 m. [3]

Uses

It produces a durable, black-striped heartwood [4] that is locally used for cabinet making, furniture and marquetry. [3] It was internationally traded, notably to produce guitar bodies and fingerboards, [4] amongst others.

Conservation status

The IUCN Red List lists Dalbergia baronii as vulnerable. [5] Its natural stands have drastically declined in response to both habitat loss and selective logging. [6] The natural habitat of Dalbergia baronii is among the most threatened Malagasy habitats. [7]

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 [8] in 2013, currently with a zero export quota. [9]
