A species similar to and compared with P. tsiangii but differing by having white flowers, longer calyx lobes and cylindrical capsules. To verify that this species is distinct, specimens of P. tsiangii were recollected from the type location at Tung-tze in northern Guizhou. Photographs of P. persimilis in the wild are included in the description. P. scopulicola, another recently described species belonging to Section Monocarpicae, grows in the same area (in fact the type specimens have sequential collection numbers). An efarinose species, leaves suborbicular, cordate base, crenate-undulate margin, with a distinct, hairy petiole, a few hairs above and especially along the nerves below. Scapes to 23cm, with usually 1 umbel but possibily up to 3 umbels of white exannulate flowers, with a narrowly campanulate calyx, pilose on the outside and split to the middle.
