twigs minutely pubescent; leaves (small), erect or spreading, lanceolate, acute, pointless, flat above, keeled beneath, piloso-ciliate; peduncles pubescent; calyx pubescent at base, the lobes lanceolate, keeled, ciliate; petals about twice as long as the calyx, the glabrous claws shorter than the calyx, limb oval-oblong, obtuse, narrowed at base; sterile filaments a little longer than the calyx, lanceolate, villous, with a subulate, glabrous, recurved point; ovary and style glabrous. Erect, 2 feet high, much branched, the branches and twigs crowded, yellowish, rather hairy, at length glabrescent. Lower leaves sub-distant, upper close, punctate beneath, with prominent nerve, 1 1/2–3 lines long, 1/3– 1/2 wide. Peduncles 4–12, filiform, 3–4 lines long. Calyx lobes 1 line long. Capsule 2 lines long, of 3 carpels.— A. platyphylla, E. & Z.! only differs from Thunberg's specimen of A. ciliata, by the leaves in that often, in this rarely, concave. Our var. β. is very like A. cerefolium β., but differs by the acuminate leaves. Var. γ. is known by denser pubescence, and ciliated keels to the leaves, etc.
