Nat. ord., Compositae.
Characters. - Leaves, the small ones or scales numerous, oblong or linear, entire and erect; the radical ones appearing much later than the flower-stems, angular and toothed, covered underneath with a loose, white, cottony wool, of which there is a little also on the upper side. Flowering stems not in tufts, as in the Common Coltsfoot, often a foot high when full-grown, with many flower-heads, of a dull pinkish-purple, in a narrow-oblong terminal panicle, and almost dioecious. The male plant has a looser panicle of smaller heads, the florets either all tubular and male (the pistil, although apparently perfect, having no ovule and forming no seed), or with a few filiform female ones on the outside; the female panicle more compact, the heads larger, the florets all filiform, or with a few tubular male ones in the centre.
A proving of this is to be found in Horn. Zeit., xxxii.
Part employed. - The young plant.
