The submersion of Pedilanthus into Euphorbia (Euphorbiaceae)
Pedilanthus (Euphorbiaceae) consists of about 15 species, all of which occur in Mexico. The genus belongs to the tribe Euphorbieae subtribe Euphorbiinae in the subfamily Euphorbioideae, and is one of six satellite genera of Euphorbia. As traditionally suspected, molecular studies have demonstrated t...

| description | Pedilanthus (Euphorbiaceae) consists of about 15 species, all of which occur in Mexico. The genus belongs to the tribe Euphorbieae subtribe Euphorbiinae in the subfamily Euphorbioideae, and is one of six satellite genera of Euphorbia. As traditionally suspected, molecular studies have demonstrated that Euphorbia is paraphyletic, and the satellite genera are nested within it. In order to create a classification of Euphorbieae subtribe Euphorbiinae that reflects evolutionary relationships and employs the concept of monophyly, I argue that the genera currently segregated from Euphorbia should be included within it. Therefore, Pedilanthus is here treated as a synonym of Euphorbia. A list enumerating the valid names for species of Pedilanthus when treated within Euphorbia is provided. The following new combinations and names are proposed: Euphorbia calcarata, Euphorbia coalcomanensis, Euphorbia colligata, Euphorbia conzattii, Euphorbia cymbifera, Euphorbia cyri, Euphorbia diazlunana, Euphorbia dressleri, Euphorbia finkii, Euphorbia lomelii, Euphorbia peritropoides, Euphorbia personata, Euphorbia tehuacana, and Euphorbia tithymaloides sspp. angustifolia, bahamensis, jamaicensis, padifolia, parasitica, retusa, and smallii. |

Pedilanthus (Euphorbiaceae) contiene alrededor de 15 especies, todas ellas se encuentran en México. El género pertenece a la tribu Euphorbieae subtribu Euphorbiinae de la subfamilia Euphorbioideae y es uno de los seis géneros satélites de Euphorbia. Como tradicionalmente se ha sospechado, los estudios moleculares han demostrado que Euphorbia es un conjunto parafilético y que los otros géneros de la subtribu se concentran dentro de él. Para tener una clasificación de Euphorbieae subtribu Euphorbiinae que refleje mejor su historia evolutiva y que siga el concepto de monofilia, es necesario que los géneros satélites se incluyan en Euphorbia. Por consiguiente, Pedilanthus aquí se trata como un sinónimo de Euphorbia. Se incluye una lista de los nombres válidos para las especies de Pedilanthus cuando se consideran como parte de Euphorbia y se proponen las siguientes combinaciones o nombres nuevos: Euphorbia calcarata, Euphorbia coalcomanensis, Euphorbia colligata, Euphorbia conzattii, Euphorbia cymbifera, Euphorbia cyri, Euphorbia diazlunana, Euphorbia dressleri, Euphorbia finkii, Euphorbia lomelii, Euphorbia peritropoides, Euphorbia personata, Euphorbia tehuacana y Euphorbia tithymaloides sspp. angustifolia, bahamensis, jamaicensis, padifolia, parasitica, retusa y smallii.
