摘要

Primulina taishanensis F.Wen & Yu Q.Chen, a new species of Gesneriaceae, from Taishan County, Guangdong Province, China, is described. It is morphologically similar to P. dryas (Dunn) Mich.Möller & A.Weber in the cuneate leaf base, bract size, purple pubescent peduncle, pistil size and white glandular hairs on the ovary. It is clearly differentiated from that species by its acuminate leaf blade apex (vs obtuse in P. dryas); pedicels 8 – 25 mm long and purple glandular pilose (vs 30 – 50 mm long, densely white villous) and anthers that are reniform and deeply constricted at the middle, c. 2.5 mm long (vs fusiform, c. 4 mm long). A provisional conservation category of Vulnerable [VU D1], according to the IUCN Red List Categories and Criteria is proposed.
