All species of this section, except C.brevirostrata C.Y.Wu et T.Y.Shu distributing merely up to 3600 m. altitude in the forest meadows, dwell in the plateau-desert, alpine scree, gravel or river banks up to 4000-5400 m. altitude. They had in common developed the specific characters adapting dryness and coolness under the natural condition of high altitude and low latitude. They are the cushion-like alpine herbs which possess taproot, leaves with flattened petio1e, 1-3 pinnatisect. The ultimate lobules of leaves elliptic or spathulate are often mucronated.
