title: Morphological and Molecular Phylogenetic Data Reveal a New Species of Primula (Primulaceae) from Hunan, China.
abstract: A new species of Primulaceae, Primula undulifolia, is described from the hilly area of Hunan province in south-central China. Its morphology and distributional range suggest that it is allied to P. kwangtungensis, both adapted to subtropical climate, having contiguous distribution and similar habitat, growing on shady and moist cliffs. Petioles, scapes and pedicels of them are densely covered with rusty multicellular hairs, but the new species can be easily distinguished by its smaller flowers and narrowly oblong leaves with undulate margins. Molecular phylogenetic analysis based on four DNA markers (ITS, matK, trnL-F and rps16) confirmed the new species as an independent lineage and constitutes a main clade together with P. kwangtungensis, P. kweichouensis, P. wangii and P. hunanensis of Primula sect. Carolinella.
