Contributor Text: I.C. Hedge
Flower/Fruit: Fl. Per.: June-August.
Type: Type: [W. Tibet] In schistosis mobilibus Koo-Khio-ghang, Jacquemont (K - photo!, P).
Distribution: Distribution: NE Afghanistan, Pakistan, NW. Himalayas, Sikkim, Nepal, Soviet C. Asia, Sinkiang, Tibet.
Comment/Acknowledgements: A low-growing high alpine species growing up to the limits of vegetation, often on barren slopes or screen. The specific epithet is rather misleading in that the leaves are scarcely heterophyllous. It is surprising that the species is common in Baltistan, known from a few gatherings in Wakhan (Afghanistan), and yet is not recorded in the intervening areas of Hunza, Gilgit or Chitral.
