Primulina yingdeensis, a new species from Guangdong, China, and P. rosulata, a new combination (Gesneriaceae), based on morphological and molecular evidence

Abstract

Based on morphological and molecular data, a new species of Gesneriaceae, Primulina yingdeensis, from Guangdong, China, is described and illustrated. It is morphologically most similar to P. hochiensis and P. hochiensis var. rosulata, but the three taxa differ from each other in discrete characters. They share yellow honey guides, but in the new species these are strongly ridged and with glands. At the same time, also based on morphological and molecular data, P. hochiensis var. rosulata is raised to the rank of species, as P. rosulata.
