Abstract

The limestone areas in south China are a major biodiversity hotspot for terrestrial biomes. Hemiboea, with 34 species and 5 varieties, mainly distributed in south China, is one of the characteristic plant groups in limestone areas. Hemiboeasuiyangensis, a new species of Gesneriaceae from limestone areas in Guizhou, China, is described and illustrated. The new species is easily distinguished from other Hemiboea species by having an oblique-infundibular corolla with an abaxially gibbous swelling on the upper half of the tube and with a densely villose throat and lower lobes. Hemiboeasuiyangensis is similar to H.omeiensis W. T. Wang in the shape of the leaf blade, but differs from the latter by the shape of the petiole, involucre, calyx and corolla and the colour of the corolla. The conservation status of this species is considered to be “Critically Endangered” (CR) according to IUCN Red List Criteria.
