Proyecto Acalypha
Acalypha project
Al igual que la flor de pascua (Euphorbia pulcherrima), la yuca (Manihot sculenta) y el árbol del caucho (Hevea brasiliensis), Acalypha es un género de plantas de la familia de las euforbiáceas. Sus cerca de 500 especies diferentes lo convierten en el tercer género con más especies del grupo, sólo por detrás de las lechetreznas (Euphorbia) y los croton (Croton), y entra dentro de lo que se ha dado en llamar géneros megadiversos por la gran cantidad de especies que presentan.
Sin embargo, el conocimiento de este género es limitado. Por ello, el objetivo de este proyecto es conocer la gran diversidad de especies que integran el grupo, principalmente en América, que cuenta con dos tercios de las especies conocidas, pero también en la región paleotropical.
Como parte de este proyecto se han publicado toda una serie de revisiones a nivel nacional para diferentes paÃses de Sudamérica: Colombia (Cardiel, 1994), Venezuela (Cardiel, 1999), Ecuador (Cardiel & Muñoz-RodrÃguez, 2012), Perú y Bolivia (Cardiel & Muñoz-RodrÃguez, 2014), y para grupos de especies que hasta ahora no se conocÃan mucho: un grupo de especies del Cono Sur sudamericano (Cardiel et al., 2013) y uno de los dos subgéneros que integran el género, el subgénero Linostachys (Muñoz-RodrÃguez et al., 2014).
Para dar a conocer los resultados disponemos de una página web con información actualizada, revisada y validada cientÃficamente. A esta página se puede acceder a través del siguiente enlace: https://www.acalypha.es.
He participado en este proyecto desde el año 2008 aproximadamente, y dentro de él hice mis trabajos de fin de carrera y de máster. Sin embargo el proyecto, encabezado por José MarÃa Cardiel, cuenta ya con un largo historial de estudios y resultados obtenidos.

A critical review of the Argentinian, Uruguayan, and Paraguayan species of Acalypha L. (Euphorbiaceae) is presented. As a result, 18 species (22 taxa) are accepted, 16 from Argentina, 12 from Paraguay, and five from Uruguay, and 49 names are considered as synonyms. Typifications are provided for A. brasiliensis Müll. Arg., A. cordobensis Müll. Arg., A. friesii Pax & K. Hoffm., A. gracilis Spreng., A. nitschkeana Pax & K. Hoffm., A. multicaulis Müll. Arg. var. glabrescens Pax & K. Hoffm., A. lagoensis Müll. Arg. var. grandifolia Chodat & Hassl., and A. striolata Lingelsh. Identification keys are also provided as are original illustrations of three species and distribution maps of all the accepted taxa.

Acalypha subgen. Linostachys (Euphorbiaceae, Acalyphoideae): a global review. Phytotaxa 166(3): 199-221.
A critical review of Acalypha subgenus Linostachys (Euphorbiaceae: Acalyphoideae) worldwide is presented. As a result 28 species, 6 of which were not previously recognized within the subgenus, are accepted and 5 new synonyms are proposed. Comprehensive nomenclatural information is supplied and 16 lectotypes and one neotype are designated. An identification key and geographic information, including a distribution map of the subgenus, are also provided. This is the first treatment of subgenus Linostachys since Pax and Hoffmann's monograph in 1924.

Synopsis of Acalypha L. (Euphorbiaceae) of Peru and Bolivia, with description of a new species. Anales del Jardín Botánico de Madrid 70(2): 152-177.
A critical review of the Peruvian and Bolivian species of Acalypha L. (Euphorbiaceae) is presented. As a result 41 species (42 taxa) are accepted, 31 from Peru and 28 from Bolivia, and 94 names are considered synonyms. A new species is described and illustrated, A. psamofila, based on Bolivian material. Comprehensive nomenclatural information is supplied and 36 lectotypes and one neotype are designated. An identification key is also provided, as well as original illustrations of six species and distribution maps of all the accepted species.

The application of the species names included in the previously invalidly published “Acalypha sect. Communes”, mostly around the widely cited A. communis, has been confusing almost since their publication. After a thorough study of the literature, from which we recorded 56 scientific names associated to this section, as well as the study of ca. 1500 herbarium specimens, including nomenclatural types, we propose a deep nomenclatural and taxonomic reorganization of this group. Acalypha sect. Communes is validly published and circumscribed to include five species: Acalypha communis, A. variabilis, A. vellamea, A. senilis and A. hassleriana. Regarding A. communis, we delimit its taxonomic status and propose five subspecies: A. communis subsp. communis, subsp. apicalis, subsp. paraguariensis, subsp. saltensis and subsp. tracheliifolia, four of them new combinations. Twenty-two lectotypes and three neotypes are designated, and 20 new synonyms are proposed. A key based on morphological characters to the species and subspecies of this section is also provided.

Acalypha carrascoana Cardiel (Euphorbiaceae), novelty for the flora of Mexico. Botanica complutensis 37: 53-56
Acalypha carrascoana Cardiel, only known from Colombia and Venezuela, is reported in Mexico, thus presenting a disjunct distribution. Comments on the systematic of related species of Acalypha section Sclerolobae Müll. Arg. are included. An identification key to the species of this section is also provided.
2012
A critical review of the Ecuadorian species of Acalypha L. (Euphorbiaceae) is presented; 20 of the 38 previously recognized species are accepted, 9 are considered synonyms and 9 are based on misidentifications. Comprehensive nomenclatural information is supplied and 13 lectotypes are designated. An identification key is also provided.
Two new species of Acalypha, A. neeana and A. machiensis, are described and illustrated based on Bolivian specimens. Comments on the systematics of related species are included.
