''Dalbergia'' is a large pantropical genus comprising about 250 species. Tropical Asia and tropical America have about 70 species each, continental Africa about 50 and Madagascar slightly over 40. In Madagascar many ''Dalbergia'' species produce high-quality wood. Some of them resemble ''Dalbergia baronii''. === ''Dalbergia davidii'' ===''[[Dalbergia davidii]]'' Bosser & R.Rabev. is similar in its leaflets, but differs in its glabrous rachis and inflorescence structure. This species is only known from a single area in western Madagascar and is classified as endangered in the IUCN Red list of threatened species; it is selectively felled for its valuable timber. === ''Dalbergia pseudobaronii'' ===''[[Dalbergia pseudobaronii]]'' R.Vig. resembles ''Dalbergia baronii'' in its leaves and flowers, but differs in its larger 1-seeded fruits. This species, classified as vulnerable in the IUCN Red list, is restricted to northern Madagascar. It is selectively felled for its high-quality timber. === ''Dalbergia tsaratananensis'' ===This is also the case for ''[[Dalbergia tsaratananensis]]'' Bosser & R.Rabev., a species from the Tsaratanana Massif in northern Madagascar, which also resembles ''Dalbergia baronii'', but differs in its leaves with fewer and slightly larger leaflets. It is classified as endangered in the IUCN Red list.
