A critical review of the Ecuadorian species of Acalypha L. Euphorbiaceae is presented; 20 of the 38 previously recognized species are accepted, 9 acalyphha considered synonyms and 9 are based on misidentifications. Comprehensive nomenclatural information is supplied and 13 lectotypes are designated. An identification key is also provided.

The Americas are home to two thirds of acaltpha species, from southeastern Canada and United States to Uruguay and northern Argentina. They thrive in a wide variety of habitats, from tropical rainforests to subdesertic areas, and from sea level up to meters of altitude.

Acalypha belongs to subfamily Acalyphoideaethe most diverse and complex in the Euphorbiaceae Hayden and Hayden This subfamily appears aloopecuroides be paraphyletic, but the central group of taxa, Acalyphoideae Beilschm. Molecular analysis support the monophyly of Acalypha TokuokaWurdack and Davis Despite its great diversity, Acalypha is one of the lesser known genera of the Euphorbiaceae.

The last treatment of the whole genus was made by Pax and Hoffmanon wich 18 species were recorded in Ecuador Table 1. The state of the knowledge of the genus in South America includes updated national floristic treatments Cardiel, Levinand checklists Bacigalupo and MulguraBerry et al.

Regarding Ecuador, the only complete work on Acalypha is the treatment of Euphorbiaceae for the Catalogue of the Vascular Plants of Ecuador Websterwhich recognized 34 species for the continental land of Ecuador and four other from Galapagos Island. This work was updated by Ulloa Ulloa and Neillwho added another four species of Acalyphabut none in the second update Neill and Ulloa Ulloa In addition Cardiel described two new species and proposed several new synonyms for Ecuadorean Acalypha.

Species of Acalypha cited for Ecuador by Pax and HoffmannWebsterand in this work; the vouchers refers to cited by Webster This work presents a reviewed critical synopsis of the species of Acalypha for continental Ecuador and provides a key to help identification. We studied Ecuadorian collections of Acalypha from the following herbaria: We reviewed all the collections cited by Webster and Ulloa Ulloa and Neillsolving the doubts raised by some names. We also found a large number of type specimens, clarifying the identity of many names.

Typifications were made after a carefully review of the original literature on the taxa, and examination of the nomenclatural types. Where no holotype was indicated, or it has been lost or destroyed, a lectotype is designated according International Code of Botanical Nomenclature rules and recommendations McNeill et al.


The structure of the checklist follows, in general terms, those of Brako and Zarucchi and Webster The accepted species are cited in alphabetical order, including original publications, homotypic synonyms and nomenclatural synonyms based on Ecuadorian collections. For each name, the information concerning the type collections is included, with studied specimens indicated with an exclamation mark!

Then, we summarize information about habit, habitat and altitudinal range in meters intervals; this information was obtained exclusively from the studied specimens. They defined three regions for continental Ecuador: Coastal, Andean and Amazonian.

The Coastal region is defined as below meters elevation, from west of the Andes to the coast, while the Amazonian region is defined in the same altitudinal range to the east of the Andes. The Andean region is defined for lands above meters elevation. Ecuadorian provinces where the species are recorded are cited in accordance with the studied collections, following the Ecuadorian provinces after the reorganization i. We indicate the total number of collections reviewed per taxa and one representative specimen voucherindicating the herbaria acronym where it is deposited.

Finally we indicate post- Webster bibliographic sources which offer updated information about the species.

Acalypha Taxonomic Information System. Our work records 20 accepted species of Acalypha for continental Ecuador. Two of them are endemic: Acalypha stellata and Acalypha websteriiacalypya two others are allochtonous: Acalypha hispida and Acalypha wilkesiana. An identification key is provided. Of the 34 species recognized by Webster for this territory, nine are considered as synonyms and nine are based on misidentifications Table 1. The four species wcalypha by Ulloa Ulloa and Neill are accepted.

We identify 17 synonyms based on Ecuadorian collections, including the new one Acalypha pilocardia Gilli. We indicate the type specimens of almost all the treated names, and 13 lectotypes are designated.
