Abstract

Two new species of Gesneriaceae, Oreocharis aimodisca and O. longipedicellata, from the limestone area of Yunnan Province, China, are described and illustrated. Their morphological relationship with similar species is discussed and colour photographs, detailed descriptions, distribution and habitat, as well as the IUCN endangered status are provided. We also discuss the accuracy of the scientific names of the described species O. tetrapterus from Guangxi, China in 2019 and O. brachypodus from Guizhou, China, in 2015, and put forward corrections related to name form.

Keywords: Oreocharis; flora of Yunnan; limestone area; morphology; new taxon.
