Primula scopulicola (Primulaceae), a new species from Sichuan, southwestern China

Primula scopulicola G. Hao, C.M. Hu & Y. Xu sp. nova (Primulaceae) is described and illustrated from Sichuan, China. From general morphology it is clearly allied to the section Monocarpicae, which is characterized by the presence of multicellular hairs, distinctly petiolate leaves, a campanulate calyx, and a globose or cylindrical capsule dehiscing by valves. Primula scopulicola is similar to P. lithophila, but can be distinguished by having smaller flowers, with calyx splitting almost to the base, and the capsule being globose rather than cylindrical. It also resembles P. cavaleriei, but can be readily separated by its calyx splitting near to the base, and by the shorter petioles.
