Abstract
Acer binzayedii, a new species of Sapindaceae from cloud and high elevation forests in Jalisco State, Mexico, is described and illustrated. Acer binzayedii is characterized by deeply sagittate anther bases bearing scattered trichomes, the wing sulcus covering more than half of the nutlet, sparsely distributed coalescent and anastomose veins of the wings with reticulate veinlets sometimes present, trichomes on the abaxial leaf surfaces with short nodulations of reduced prominence, conical buds, and grey bark with long vertical ridges. The new species is compared to putative relatives A. skutchii, A. floridanum, A. saccharum, A. grandidentatum, and A. nigrum.
Resumen
Acer binzayedii, especie nueva de Sapindaceae de los bosques nubosos en elevaciones altas en el estado de Jalisco, México, se describe e ilustra. Acer binzayedii se caracteriza por la antera pronunciadamente sagitada en la base con tricomas esparcidos, el surco del ala cubre más de la mitad del fruto, las venas coalescentes y anastomosas del ala están espaciadamente distribuídas con venas secundarias reticuladas algunas veces presentes, los tricomas en el lado abaxial de la hoja con nódulos cortos de prominencia reducida, yemas cónicas, corteza gris con costillas largas verticales. La especie nueva se compara con los parientes más cercanos A. skutchii, A. floridanum, A. saccharum, A. grandidentatum, y A. nigrum.
