MACKAY.

Perennial.-Flowers from July to October.

Root fibrous, fibres many, long, simple, thread-shaped, dark brown on the outside, white within. Stem from 1 to 3 feet high or more, upright, leafy, round, unbranched, almost solid, scored; either slightly hairy, or quite smooth. Leaves numerous, scattered, sessile, strap-spear-shaped, distantly toothed, bright green on the upper surface, paler on the under; their margins and ribs slightly hairy. Flowers bright yellow, about an inch in diameter, on branched, somewhat cottony flower-stalks, which terminate the stem in a corymbose form, or more generally in a kind of imperfect umbel. Bracteas awl-shaped, few and small. Involucrum (calyx of Linn.) dark green, almost smooth, except at the very base; its scales strap-spear-shaped, a little spreading or recurved at their tips. Seeds (fig. 4.) angular, brown, and finely dotted. Pappus (figs. 4 & 5.) rough (see fig. 6.), as long as the involucrum. Receptacle (fig. 7.) slightly cellular, and rough with small, awlshaped, chaffy scales.

This species is subject to much variation in size, shape, smoothness, &c. of the leaves; and in the disposition of the flowers. There is a variety sometimes met with wild, with very narrow, quite entire, strap-shaped leaves; and a simple, 1-flowered stem; this is var. y. of Sir J. E. SMITH'S Engl. Flora; and the Hieracium Pulmonaria Graminea of DI LENIUS, in RAY's Synopsis, p. 168; and PETIVER'S Herbarii Britannici, t. 13. f. 12. DILLENIUS mentions it as having been found about London; and Mr. WoODWARD informs us, in WITHERING'S Arrangement of British Plants, that it is frequent near Bungay, in Suffolk.-An English specimen of this very marked variety, collected, probably, either by SHERARD, or by DILLENIUS, is preserved in the Sherardian Herbarium, in the Oxford Garden.

Hieracium umbellatum is said to be used in Sweden to dye yaru of a fine yellow colour. It is one of the most decidedly marked of any individual in this very difficult and extensive genus; of which Mr. LouDON, in his Hortus Britannicus, enumerates 123 species, most of them natives of different parts of Europe.

GEN. CHAR. Involucrum (common Calyx) (fig. 1.) oblong, imbricated; scales strap-shaped, pointed, upright, very numerous; the innermost longest, all nearly equal. Corolla compound, radiant; florets of the disk (see fig. 2.) numerous, perfect, funnel-shaped, regular, their limb in 5, sometimes said to be but 4, equal segments; florets of the ray (see fig. 3.) numerous, in a double row, tubular at the base, the limb very narrow, strap-shaped, tapering, nearly upright, either entire, or slightly toothed. Filaments (see fig. 4.) 5, in the florets of the disk only, hair-like, very short. Anthers (see figs. 2 & 4.) in a cylindrical tube, simple. Germen (see figs. 2, 3, and 4.) inversely egg-shaped, angular. Style (see figs. 3 & 4.) thread-shaped. Stigmas (see figs. 2, 3, & 4,) 2, oblong, a little prominent, slightly spreading. Seed-vessel none but the converging calyx. Seed (see figs. 5 & 6.) small, inversely egg-shaped. Pappus (see figs. 5 & 6.) sessile, simple, rough, as long as the florets. Receptacle (see fig. 5.) flat, naked, slightly cellular.

Distinguished from other genera in the same class and order by the imbricated involucrum of numerous strap-shaped, pointed scales; the naked receptacle; the numerous, strap-shaped, very narrow florets of the ray, in a double row; and the sessile, simple pappus. Three species British.
