Anemone decapetala

Native to Ecuador, Peru, southern Brazil, Uruguay, Chile, and Argentina, this perennial herb grows from a tuber. It occurs in open grasslands and sparsely wooded places. Its white, petal-like sepals surround numerous stamens and a cluster of small individual ovaries; the flowers have no true petals. After flowering, each ovary develops into a one-seeded fruit. Long woolly hairs cover these fruits, giving the mature seed heads a fluffy appearance and helping with dispersal. Photographed in Peru.
