Long, thin rhizome, glabrous, efarinose. Elongate lamina, sinuate-dentate leaf-margin with blunt teeth and less incised calyx (cut to 1/3). More information on variation is needed for this species. The last 6 images represent the species from near Daguan, NE Yunnan. Authorities have differed on which Section this species belongs to, and the last images seem to indicate an affinity with P. petelotii and suggest it should be a member of Section Chartacea. See other members of Section Chartacea: P. lacerata, P. veitchiana, P. chartacea, P. petelotii and P. wenshanensis. It is unclear what this means for the synonyms usually associiated with P. sinuata.
