An updated checklist of Lysionotus (Gesneriaceae) and two new species from southwestern China

By reviewing the taxonomic history of Lysionotus, we provide an updated checklist of the species currently accepted in the genus. Currently, 39 species, one subspecies, and four varieties are recorded in the genus. For every species, subspecies, and variety, the scientific name along with the corresponding references is provided. In addition, two new species, Lysionotus purpureopunctatus and Lysionotus guiliangii, are described and illustrated. Lysionotus purpureopunctatus was discovered in Guizhou Province, China, while L. guiliangii was found in Yunnan Province, China. Lysionotus purpureopunctatus is similar to L. denticulosus and L. oblongifolius, and Lysionotus chingii is morphologically close to L. gracilis but can be clearly distinguished by morphological features.
