var. laciniifolia Grey-Wilson

As seen in cultivation, this is very distinct in its roundish leaflets, blunt at the apex, incised or three-lobed, sometimes to the base. Introduced by Grey-Wilson and Phillips from the Dolpo region of inner Nepal; according to the former (op. cit.), it is common in the Kali Gandaki gorge.As for C. tibetana, this was described from specimens collected by Strachey and Winterbottom in a bleak region of southern Tibet just north of the border with Kumaon (the section of the Himalaya west of Nepal). In its typical state (subsp. tibetana) it differs from subsp. vernayi in its less thick and more pointed sepals. The flowers may be deeply stained with brown or purple on the outside, and some marking also occurs in subsp. vernayi.
