Closely related to P. turkeviczii (formerly P. lactiflora) also from the same area but which is white flowered with a violet tube. White forms of P. kaufmanniana exist but in P. turkeviczii the leaves are thinner, more membranous and the petioles, scape and pedicels are very slender and the tube is narrower. P. kaufmanniana resembles the more familiar P. cortusoides but with orbicular leaves, cordate at the base, divided into blunt lobes. P. kaufmanniana is hairy, especially the scape and the veins on the underside of the leaves. Flowers are bright violet-rose with a long tube.
