Abstract

A new species of Gonolobus from northwestern Mexico with green and barbate corollas is described here. Gonolobus naturalistae is morphologically similar to G. barbatus, G. pectinatus, and G. sororius but differs in corolla and corona morphology and distribution. Descriptions, illustrations, morphological comparisons, and geographic distribution maps of these species, as well as their conservation status, are provided. This discovery highlights Mexico as a center of diversity for the genus, with around 40 species recorded, and highlights its endemism, with 48.7% of the species occurring in the country.
