Suppl. Pl., 52, 316. 1782. name conserved
Shrubs or trees [lianas], unarmed. Stems erect or scandent, young growth densely strigose or villous or glabrescent, peduncles and pedicels eglandular. Leaves alternate, odd-pinnate or unifoliolate; stipules present, caducous; petiolate; leaflets 1–5[+], alternate, stipels absent, blade margins entire, surfaces glabrous or pubescent. Inflorescences 10–50-flowered, axillary [lateral or terminal], racemes, panicles, or corymbs; bracts present; bracteoles paired proximal to calyx. Flowers papilionaceous; calyx campanulate, lobes 5; corolla usually white, creamy white, or yellowish, sometimes pinkish [purple], glabrous; stamens 9 or 10, monadelphous or diadelphous [triadelphous]; anthers basifixed, relatively small, dehiscing apically; style glabrous; stigma terminal, small. Fruits legumes, stalk present, compressed, straight, compressed, narrowly ellipsoid to oblong or subglobose to subreniform, indehiscent, often winged (samaroid), glabrous or pubescent. Seeds 1–4[–6], reniform; hilum lateral. x = 10.
Distribution
Florida, Mexico, West Indies, Central America, South America, Asia, Africa, tropical to warm temperate areas.
Discussion
Species ca. 100 (3 in the flora).
Dalbergia includes important timber species prized for the color and grain of the wood (M. Chudnoff 1984).
