Anemonoides lancifolia (formerly known as Anemone lancifolia), the lanceleaf anemone or mountain thimbleweed, is an herbaceous plant species in the family Ranunculaceae.[1] Plants grow 20 to 30 cm tall, growing from a horizontally orientated rhizome, flowering mid spring to early summer. The flowers have white sepals that are 12–20 mm long. This species much resembles Anemonoides quinquefolia, of which it was formerly considered a subspecies,[1] except that it is larger growing. After flowering fruits called achenes are formed in a small cluster, each achene is 3.5–5 mm long, lacks wings and has a straight or partly curved beak that is 1–1.5 mm long.
