Abstract

This work presents a critical nomenclatural review of the Acalypha species of the Western Indian Ocean Region (Madagascar, the Comoros Archipelago, the Mascarene Islands and the Seychelles Archipelago). This is the first treatment of Acalypha of Madagascar since Leandri’s monograph in 1942. A total of 151 scientific names related to Acalypha from this region are treated. We recognise 35 species (28 native and seven introduced), treat 93 names as synonyms (28 of them for the first time) and identify three as doubtful or excluded names. We designate lectotypes for 41 names, make two new combinations and propose one new name.

Highlights

This work is part of the taxonomic and biogeographic revision of Acalypha (Euphorbiaceae) in the Western Indian Ocean Region (WIOR)
In 1891, Baillon, in his contribution to Grandidiers Histoire Physique, Naturelle et Politique de Madagascar, provided 10 excellent plates of Acalypha species from Madagascar, five of which are cited for the first time (Baillon 1891)
We record 151 published scientific names related to Acalypha of the WIOR (Table 1)
