[From the Greek, anemos, wind; because many of the species grow in elevated bleak situations.] 



Involucre of 3 leaves, remote from the flower ; the leaflets variously incised. Sepals 5 to 15, 



petaloid. Petals none. Achenia mucronate (sometimes with a long plumose tail). — 



Perennial herbs, with radical (usually divided) leaves. Scapes, when branched, bearing 



leaf-like involucres at each division. Peduncles one-flowered.
