This species was first collected in Central Guizhou, "south of Tin-fan, grande grotto of Lin-tchouan". A collection of Cavalerie specimens collected from 1900-1920 and purchased by Kew and Edinburgh were all marked as coming from Yunnan, but this is obviously an error. This may explain why the Flora of China lists the location for this species as both C Guizhou and SE Yunnan as I have no further information on this species in Yunnan. An efarinose species, leaves suborbicular, more of less pilose with a distinct pilose petiole, cordate base, margin obscurely crenate-lobulate, minutely denticulate. Scapes to 22cm with 1-4 umbels of bluish exannulate flowers, calyx campanulate cut to middle. Capsule globose. Compare with related P. lithophila and P. scopulicola.
