Abstract:A new species of Primula is described and illustrated under the name of P. hydrocotylifolia G. Hao, C. M. Hu & Y. Xu. From general morphology it is clearly allied to the species of section Petiolares subsection Chartacea, which is characterized by the plants being glabrous and efarinose, lacking bud-scales at flowering time, the globose capsule including in the persistent calyx, not opening by valves but crumbling at the membrane apex, and by the leaves with more or less rounded blades and slender petioles. The new species superficially resembles P. veitchiana, but the latter can be easily distinguished by its much taller stature, many-flowered inflorescence and larger flowers.
