Coptis trifolia. (Coptis, to cut, alluding to the divided leaves.) - Family, Crowfoot. Sepals, 5 to 7, falling early. Petals, same number, club-shaped, small, thick, fleshy, and hollow at apex. Stamens, numerous. Pistils, 3 to 7, stalked. Flowers on leafless scapes, not conspicuous. Leaves from the root, 3-lobed, the leaflets sharply toothed, shining, evergreen. Stems, low, smooth. May to July.
The beauty of the plant lies in the leaves, which nestle among bog-mosses and are bright and shining the summer through. The "goldthread" appears when we dig up the root and find it composed of long, yellow fibers.
