Wilding, N., P.B. Phillipson & S. Crameri (2023). Taxonomic studies on Malagasy Dalbergia (Fabaceae). V. Eight new large tree species and notes on related Malagasy species. Candollea 78: 99–124. In English, English and French abstracts. DOI: http://dx.doi.org/10.15553/c2023v782a2 An ongoing revision of Malagasy Dalbergia L. f. (Fabaceae) has increased the number of recognized species from 48 to 64. Fifty-two (52) of the 64 are considered to grow large enough to be of potential commercial interest for their valuable timber. Eight large tree species, mostly from the north and west of Madagascar, are described and illustrated here for the first time, namely Dalbergia bosseri N. Wilding, Phillipson & Crameri; D. karatrae N. Wilding, Phillipson & Crameri; D. leandrii N. Wilding, Phillipson & Crameri; D. oronjiae N. Wilding, Phillipson & Crameri; D. rajeryi N. Wilding, Phillipson & Crameri; D. rakotovaoi Phillipson, N. Wilding & Crameri; D. sambavensis N. Wilding, Phillipson & Crameri and D. soafarae N. Wilding, Phillipson & Crameri. Risk of extinction assessments using the IUCN Red List criteria are provided and indicate that all eight species are threatened.
