Grassy slopes; 2700–4500 m. Gansu, Qinghai, Sichuan, SE Xizang, NW Yunnan.

This variety has reputed medicinal value (in Xizang). Some authors consider Hymenidium (Trachydium) chloroleucum (including Pleurospermum likiangense) to be a separate taxon, differentiated by the less dissected leaflets and bracteoles with a pinnate apex. Further work is needed on this complex group.
