摘要
Two new species of Dalbergia L. f. (Fabaceae: Dalbergieae) are described from northern Madagascar: Dalbergia antsirananae Phillipson, Crameri & N. Wilding and Dalbergia obcordata N. Wilding, Phillipson & Crameri, and an emended description is provided for a third species, Dalbergia manongarivensis Bosser & R. Rabev. All three species are illustrated with line drawings and photographs, and each is provided with a risk of extinction assessment using the IUCN Red List criteria: all three species are assessed as "Endangered". Dalbergia antsirananae and Dalbergia manongarivensis are closely related, and both appear to be a source of valuable wood, while Dalbergia obcordata is only known as a shrub and is assumed not to produce wood of commercial value.
