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.

This work is part of the taxonomic and biogeographic revision of Acalypha (Euphorbiaceae) in the Western Indian Ocean Region (WIOR). According to the Taxonomic Databases Working Group standards (Brummit 2001), this region includes Madagascar, the Mascarene Islands (Mauritius and the French Department of Réunion), the Comoros Islands (Union of the Comoros and the French Department of Mayotte) and the Seychelles Archipelago. There are no species of Acalypha known from any of the smaller Scattered Islands of the Western Indian Ocean.
The first two species of Madagascan Acalypha (A. filiformis and A. venosa) were described by
In the treatment of Acalypha for Engler´s Das Pfanzenreich,
Only three floristic works included Acalypha species from the other islands of the Western Indian Ocean region.
While undertaking this nomenclatural review, we found 144 names related to Acalypha from the study area, many of which involved serious problems of taxonomic identity. All of these names have been evaluated in this work and our interpretation of their current taxonomic status and distribution is presented in Tables
We conducted a thorough bibliographical review and consulted the following herbaria for the Western Indian Ocean Acalypha types: B, BM, BREM, BRNU, C, CAS, G, GB, GDC, GH, JE, K, M, MA, MAU, MO, MPU, NY, P, S, US, TAN, TUB and W (acronyms according to
The accepted species are cited in alphabetical order and all known synonyms are included, except for the introduced species. We include the notation “syn. nov.” whenever we newly treat a taxon as a synonym. We provide details of the type collection(s) for each name. Lectotypes are designated after a careful review of the relevant original literature and examination of the nomenclatural types.
Five of the Acalypha treated names were illustrated first, without description, in Baillon`s Histoire Naturelle des Plantes (
When two or more syntypes were cited in the protologue, a lectotype is designated, using the best preserved specimen or the one most consistent with the protologue. The remaining syntypes are also cited.
The type locality information is taken mainly from the type specimen labels. We add additional information such as the province name of Madagascar or a modern or accepted spelling of a place name. If the locality is ambiguous or imprecise, we keep the literal citation (in quotation marks) as it appears in the protologue. Barcode numbers of type specimens are cited when available.
Under the “Distribution” section, we list the general distribution of each species in Africa (following Brummit 2001), if they occur there and in the WIOR region. We include the Madagascar provinces or island names within the studied archipelagos where they occur. This information should be taken as preliminary until a more complete study of the genus, in progress, is completed.
In the references section, we only include references which cite Acalypha in the WIOR region.
All information gathered as part of this work, including the complete listing of studied specimens, is available online at the regularly updated Acalypha Taxonomic Information System website, www.acalypha.es (
In the present work, we record 151 published scientific names related to Acalypha of the WIOR (Table

In the Comoros Archipelago, there are seven species of Acalypha, four native (one endemic) and three introduced, one of which, A. bailloniana, is first reported here. There are seven species on the Mascarene Islands, three native (all endemic) and four introduced. There are four species on the Seychelles, one endemic and three introduced.

Acalypha gracilipes has been usually treated as a variety of A. integrifolia Willd., which is endemic of Mascarene Islands, but A. gracilipes can be clearly distinguished by its elliptic-lanceolate leaves, denticulate female bracts and glabrous and glandular ovaries, vs. linear-lanceolate leaves, entire female bracts and hispidulous and echinate ovary in A. integrifolia.
A. gracilipes can be distinguished from both A. urophylla Boivin ex Baill. and A. paxii Aug.D.C. mainly by its glabrous leaves with crenate to subdentate margins and obtuse to subacute apices, glabrous female bracts and glabrous ovaries with minute sessile glands, vs. pubescent leaves with serrate margins and acuminate (A. urophylla) or usually caudate (A. paxii) apices, pubescent female bracts and hispidulous ovaries with long papillae. In addition, the female bracts of A. paxii have a prominent central tooth, which is absent in both A. gracilipes and A. urophylla.

Introduced in Tropical Africa and the WIOR. Madagascar (Toliara).
This shrub, native to Melanesia or Malesia, is frequent in gardens throughout the tropics and rarely appears naturalised. As all plants are pistillate, it can only reproduce clonally. We found collections from Madagascar and Seychelles where it is cultivated. It has been reported from Madagascar (

Acalypha paxii was proposed by August De Candolle as a replacement name for the illegitimate A. urophylla Pax.
Acalypha paxii, A. pervilleana and A. meiodonta have been considered synonyms of A. reticulata, which we consider to be a synonym of A. filiformis. A. paxii can be differentiated from A. filiformis by its sessile, dentate female bracts with a prominent central tooth vs. pedicellate, crenate to subentire female bracts in A. filiformis (see notes in A. filiformis).
Acalypha paxii can be distinguished from A. urophylla, which has also been placed within A. reticulata, mainly by its leaves with usually caudate apices, its dentate female bracts with a prominent central tooth and eglandular margins vs. leaves with usually acuminate apices, dentate female bracts without a prominent central tooth and with small sessile glands at the margins. See notes under A. gracilipes Baill. for the differences between A. paxii and that species.
Acalypha humblotiana was first illustrated, without description, in
Although Richard 384 [P00536745]! and 385 [P04779454]! have labels giving the locality as “Bourbon”, now Réunion, these are not Richard’s original labels and the species is otherwise unknown from the Mascarene Islands. We do not have evidence that it occurs there.

The specimens, indicated as isolectotypes, do not have Richard’s original label. They instead have labels with Baillon’s handwriting giving the location as “Madagascar”. We believe that the correct location is the one indicated on the selected lectotype, “Ile Mohilla”, whose current name is Mohéli, in the Comoros Archipelago. A search of specimens at P showed that Richard’s collections numbered 284–286, 288, 290, 291 and 293 are also from Mohéli (289 has no locality and 292 is not listed). Richard 544 has an apparently original label showing the locality only as “Madagascar.” Collections at P with nearby numbers are labelled as being from either “Nord de Madagascar” or ”Ile Nos-bé” (now Nossi-bé), so this collection could be from northern Madagascar, although we have seen no other specimens from outside the Comoros Archipelago.

The holotype of Acalypha buchenavii should be at BREM but Rutenberg’s specimens arrived at BRNU after World War II. Originally in the Überseemuseum in Bremen (BREM), they were transferred to northern Moravia (Czechia was at that time a Protectorate of Nazi Germany) to save them from potential destruction by bombardment. After the collapse of the Nazi regime, these collections were confiscated as “German property” and sent to BRNU.
