Description
Anemone oregana is a perennial herb growing from a thick rhizome, generally Шаблон:Cvt high, but exceptionally to Шаблон:Cvt. A single basal leaf made up of three large leaflets on a Шаблон:Cvt petiole may be present. The inflorescence consists of a single tier of three leaflike bracts and a single flower. The bracts are similar to the basal leaf when the latter is present. The terminal leaflet may have a petiole or may be sessile. Its margin is sharply toothed on the distal half or third and its tip is pointed. Lateral leaflets may have a single lobe. The flower has no petals but 5 to 7 petal-like sepals in any of several colors, usually blue or purple but sometimes reddish, pink, white, or bicolored. In the center of the flower are up to 75 thin stamens. The fruit is a cluster of achenes.Шаблон:RШаблон:R
