Abstract

A new species, Primulaxilingensis K.Huang & Z.X.Fu, sp. nov. (Primulaceae), is described and illustrated. In gross morphology, it is clearly allied to section Minutissimae on account of having stolons, being glabrous, leaf rosette less than or equal to corolla, flower solitary and bract not swollen at base. The new species is easily distinguished by the combination of scape densely yellow farinose, leaf apex acute, rarely broadly obtuse, corolla pale purplish blue and style 3.0-6.0 mm above base of corolla tube, stamens reaching the corolla tube mouth in thrum flower. In addition, the distribution map, morphological comparison of related species and conservation status of the new species are also provided.

Keywords: Primula sect. Minutissimae; conservation; morphological characters; taxonomy.
