Abstract
Primulina yangmingshanensis F.Wen & K.Liu, a new species of Gesneriaceae from Hunan, China, is described and illustrated. The new species is morphologically similar to P. latinervis (W.T.Wang) Mich.Möller & A.Weber, P. roseoalba (W.T.Wang) Mich.Möller & A.Weber and P. pseudoroseoalba Jian Li, F.Wen & L.J.Yan, but this novel taxon can be effectively distinguished from three morphologically convergent species on the basis of several shared diagnostic characters. Photographs and descriptions of the new species are provided below. According to the IUCN Red List Categories and Criteria, P. yangmingshanensis is preliminarily assessed as Vulnerable (VU D1+2).

Diagnosis: Primulina yangmingshanensis superficially resembles P. latinervis, P. roseoalba and P. pseudoroseoalba in leaf blade shape. However, it clearly differs from them by its bigger bracts ovate to orbicularovate in size 2.5–5.0 × 2.0–3.5 cm. Additionally, it differs from P. latinervis by pedicel densely pubescent and glandular pubescent (vs. puberulent), anthers densely pubescent (vs. glabrous), pistil densely glandular pubescent and puberulent (vs. puberulent); from P. roseoalba by peduncle and ...
Etymology: The specific epithet of this new species, "yangmingshanensis", is derived from the type locality where this species is found. The type locality is situated in the limestone areas around the foothills of Yangming Mountain, a renowned mountain in Hunan. Therefore, the specific epithet "yangmingshanensis" originates from "Yangming Mountain."
