- n lewisia A genus of polypetalous plants belonging to the natural order Portulaceæ, the purslane family, distinguished by having from 5 to 8 sepals and from 8 to 10 petals. There are but 2 species, herbs with narrow woolly leaves and handsome rose-colored flowers open only in sunshine, found only in northwestern North America. One species, L. rediviva, is used as food by the Oregon Indians. It is the bitter-root (racine amère) of the early French settlers, and is said to be very nutritious. It is also called tobacco-root, because when cooked it has a tobacco-like odor. These plants are hardy and ornamental in cultivation.
