Flower/Fruit: Fl. Per.: May-June.
Type: Syn-types: Kurram: Shalizan stream, June 1879, Aitchison, hill north of Kaiwas, 10000'-11000', July 1879, Aitchison 733 (K).

As already stated by the authors the plant seems to be closest to Clematis alpine (L.) Miller, though the petaloid staminodes without the anthers are lacking. Characters of both true Clematis and Atragene are united in this unique species. According to Aitchison & Hemsley (l.c.) the same combination of characters is also found in the N. American Clematis verticillaris DC.

Distribution: Distribution: Endemic, found only in the Kurram valley.
