A New Species of Varronia (Cordiaceae, Boraginales) from Northeastern Brazil
Abstract—
Varronia mariana (Cordiaceae, Boraginales), a new species from the Brazilian semiarid region, is described here. The new species is distinguished from other known Varronia species with cephaloid inflorescences by the indumentum with uncinate trichomes, calyx lobes that are acute to slightly acuminate, and a shorter corolla. A complete morphological description, illustration, data on distribution, habitat, and phenology, and comparisons with morphologically related species are provided.
