Abstract
Primula longipilosa from SW Yunnan, China, is described as a species new to science and illustrated. The systematic placement of this new species is also discussed based on an nrITS molecular tree. It is morphologically most similar to P. mollis, but differs from the latter in its racemose inflorescence, green calyx tube, pink to pink rose corolla, stamens at 1/3 length above the base of the corolla tube and applanate globose capsule.
Keywords: Morphological characteristics, nrITS, phylogenetic analysis, Primula mollis

Primula longipilosa Ze H. Wang & H. Peng, sp. nov.
Diagnosis: Primula longipilosa is most similar to P. mollis in the long soft multicellular hairs all over the plant, the shape of their leaves and corolla. But it differs from the latter mainly in its racemose inflorescence, green calyx tube, pink to pink rose corolla, stamens of the pin flowers at 1/3 length above the base of corolla tube, and applanate globose capsule. The main morphological differences between P. longipilosa and P. mollis are summarized in Table 1.
Distribution and habitat: Primula longipilosa is currently encountered and seen growing on the moist mountain slopes along the valley forest margin near the new Aiguo Village, Gengma County, Yunnan Province, China.
Etymology: The specific epithet refers to the impressive long spreading white soft multicellular hairs on the whole plant.
