GEN. CHAR. Involucram (common calyx) (fig. 1.) imbricated; scales spreading, outer ones terminated by a leafy appendage. Corolla compound, radiant; florets of the disk (fig. 2.) numerous, perfect, tubular, with 5 equal segments; florets of the ray (fig. 6.) strap-shaped, 3-toothed, yellow. Filaments (see figs. 4 & 5.) 5, in the florets of the disk only, thread-shaped. Anthers united into a cylindrical tube, with bristles at their base (see fig. 5). Germen (see figs. 2 & 3.) in all the florets fertile, oblong. Style (see fig. 5.) thread-shaped, cloven. Stigmas spreading, oblong, rather obtuse. Seed-vessel none, but the unaltered calyx. Seed (see fig. 7.) linear, quadrangular. Pappus (see fig. 7.) roughish, simple. Receptacle (see fig. 8.) naked.

The imbricated involucrum of many spreading scales, the outer ones terminated by a leafy appendage; the anthers with 2 bristles at their base; the naked receptacle; and the simple pappus; will distinguish this from other genera, with radiant flowers, in the same class and order.

The leaf-like scales of the involucrum will distinguish it from Limbárda, and the simple pappus from Pulicária, (t. 170).

One species British.

I'NULA HELENIUM. Elecampane. Scab-wort. Horse-heal. SPEC. CHAR. Leaves clasping the stem, egg-shaped, somewhat toothed, wrinkled, downy beneath. Scales of the involucrum eggshaped, downy.

Perennial. Flowers in July and August.

Root thick, branching, brown, aromatic, and mucilaginous. Stem from 3 to 5 feet high, upright, leafy, round, furrowed, downy; branched towards the top. Lower leaves large, stalked, spearshaped; upper leaves egg-spear-shaped, sessile, clasping the stem, serrated, veiny, deep green, slightly hairy above; whitish-green, and downy underneath. Flowers large, solitary, terminating the stem and branches. Scales of the involucrum broad, recurved, leafy, finely downy on both sides. Florets all yellow; those of the ray long and narrow, each terminating in 3 unequal teeth. Seed quadrangular, smooth. Pappus roughish. Receptacle reticulated, not quite smooth or naked.

This is the Elecampane of the shops; the root is esteemed a good pectoral; and the scab in sheep is cured by a decoction of it. Bruised and macerated in urine with balls of ashes and wortle-berries, it dyes a fine blue colour. An infusion of the fresh root, sweetened with honey, is considered an excellent medicine in the hooping cough. Horses and goats eat this plant; cows, sheep, and swine refuse it.
