A new species, Primula luquanensis Z.K.Wu and Wei Zhou sp. nov. (Primulaceae) is described and illustrated from Yunnan Province, China. It is morphologically assigned to P. sect Aleuritia based on its dwarf and hairless habit and coverage by farina on both sides of the leaf blade and scape. This new species is similar to P. nutantiflora and P. yunnanensis, but it is easily distinguished by its stolons, solitary bract, bell-shaped corolla and monomorphic floral form. The new species also has a substantially reduced corolla tube, presenting a unique floral form in a genus where heterostyly typically prevails.
