A New Rupicolous Palm From the Campos Rupestres, Minas Gerais, Brazil

Abstract

The Syagrus glaucescens species complex occurs in the Espinhaço Range in Minas Gerais state, Brazil. In addition to Syagrus duartei Glassman, S. glaucescens Glaz. ex Becc. and S. evansiana Noblick, a fourth undescribed species was previously identified by its morphology, leaf anatomy and geographical isolation. Here we formally describe this species as new to science and compare it with Syagrus evansiana, its closely related species. We also provide a distribution map, illustrations, photographs, taxonomic notes, and an IUCN conservation status assessment of Endangered.
