Hololeion krameri is a perennial herb 0.5-1m-in-height borne in marshes or water's edges in foothills or wildernesses. It extends runners underground long to propagate it into colonies. Leaves, 15-50cm long, 1-3cm in width, linear-lanceolate-shaped, radiate from the bases of the plants or gather at the lower parts of the plants, and their tips have sharp points, and leaves on upper parts are significantly small. The stem tops produce sparse 3-3.5cm across yellow flower heads. Bloom time: September-October.
