Achenes elongated at maturity, club-shaped, beset with stalked glands above; pappus none.--Slender perennials, with the alternate thin and petioled leaves smooth and green above, white-woolly beneath, and few small (whitish) heads in a loose panicle, beset with glands (whence the name, from ἀδήν, _a gland_, and καυλός, _a stem_). 1.

Achenes more or less 4--5-ribbed; pappus simple, of capillary bristles.--Coarse herbs, not floccose-woolly, with alternate simple leaves, and large yellow flowers. (The ancient Latin name.) I. HELÈNIUM, L. (ELECAMPANE.) Stout perennial (3--5° high); leaves large, woolly beneath; those from the thick root ovate, petioled, the others partly clasping; rays very many, narrow.--Roadsides and damp pastures. Aug.--Heads very large. Root mucilaginous. (Nat. from Eu.) 36. POLÝMNIA, L. LEAF-CUP. Heads broad, many-flowered, radiate, rays several (rarely abortive), pistillate; disk-flowers perfect but sterile. Involucral scales in two rows; the outer about 5, leaf-like, large and spreading; the inner small and membranaceous, partly embracing the thick triangular-obovoid achenes. Receptacle flat, membranous-chaffy. Pappus none.--Tall branching perennial herbs, viscid-hairy, exhaling a heavy odor.
