Abstract

Populus primaveralepensis A.Vázquez, Muñiz-Castro & Zuno sp. nov., a new species from relict gallery cloud forest in Bosque La Primavera Biosphere Reserve (Mexico), is described and illustrated. The new species belongs to P. subsect. Tomentosae Hart., and is morphologically similar to P. luziarum A.Vázquez, Muñiz-Castro & Padilla-Lepe, but differs from it in having taller trees without root suckers, white and ringed young stems and branches, a branching angle of ca 45º, leaves with higher blade to petiole ratio, leafs frequently elliptic or ovate to widely ovate (vs widely ovate to ovate-deltoid), denser inflorescences, and shorter capsules. The conservation status of the species was assessed as Critically Endangered (CR).
