A new perennial species of Portulaca (Portulacaceae) from central Mexico

GILBERTO OCAMPO

Abstract


Portulaca juliomartinezii is described here as a new species from the Mexican states of Guanajuato and Querétaro. It is a perennial species with fusiform roots, magenta flowers, and a hemispheric operculum, a set of characters that segregate it from other taxa like P. mexicana and P. pilosa. Although the molecular phylogenetic analysis is not clear about the sister relationships of P. juliomartinezii, the new species was found to be member of a high-supported clade within the Pilosa clade.
