Hieracium Senescens, Backh

The habitat of this plant is grassy slopes and edges of streams in mountain districts, in crevices, mountain ledges, chiefly on mica schist, rarely on granite. The plant is green, with a stiffly hairy, woolly-felted, glandular stem. The radical outer leaves are oval, rounded above, the inner oval, lance-shaped, blunt or acute, narrowed to the stalk, entire, toothed, the inner leaves sharply toothed below, with few stiff hairs. The stem-leaves are 1-2 or none. The lower are lance-shaped, linear, long, stalked, the upper bract-like. The 1-4 heads are egg-shaped, conical below, on long arching stalks. The phyllaries meet together in the bud, the outer being narrow, linear, the inner lance-shaped, linear, acute, the innermost narrowed, woolly-felted, hairy, glandular. The ligules are yellow, stiffly hairy or smooth. The styles are yellow. The plant is 15-18 in. in height. It flowers in July and August, and is a herbaceous perennial.

The stem-leaf is solitary, large, stalkless or shortly-stalked, like the inner radical leaves. The 1-6 heads are large, dark, rounded below, on long arching, wavy, woolly-felted, stiffly hairy, glandular stalks. The dark olive-green phyllaries are broad, the outer short, loose, the intermediate linear, blunt, acute, senescent, hairy and glandular. The ligules are golden, stiffly hairy at the tip. The styles are broad. The plant is 7-16 in. high, and flowers in July and August, being a herbaceous perennial.

Hieracium Chrysanthum, Backh

The habitat of this plant is lofty mountains in Scotland, alpine glens, grassy slopes, ledges, stony margins of lakes, rocky burns, on granite, mica-schist, and hornblende. The plant is green, with a stiffly hairy, glandular, woolly-felted stem branching from the base. The radical leaves are bright-green, glossy, the first leaves spoon-shaped, inversely egg-shaped, the later oblong, elliptic, oval, rounded, blunt above, irregularly sharply toothed below, the inner oblong, lance-shaped, acute, the teeth long, the base wedge-shaped, hairy below and on the border. The stem-leaves are solitary or wanting, stalked, narrow, lance-shaped, with acute teeth, with a linear bract-like leaf above. The heads are usually 1-3, black, rounded below. The stalks are short, straight or wavy, hairy, and glandular. The phyllaries are long, extending forwards, the outer small, loose, the inner long, linear, narrowed from a broad base, acute, bristle-like, senescent, hairy, and slightly glandular. The ligules are orange-yellow, the inner fringed with hairs. The styles are yellow, livid. The plant is 9-15 in. in height, flowering in July and August, and is a herbaceous perennial.

Hieracium sinuans, F. J. Hanb. - The habitat of this plant is lofty mountain glens, ravines of mountain streams, moist ledges in the glens. The stem is hollow, simple or branched, stiffly hairy, woolly-felted, hairy, and glandular above. The radical leaves are green to red, the first ones spoon - shaped, inversely egg-shaped, the later oblong, rounded, blunt above, the inner narrow to oblong, lance-shaped, with a long narrow point, the margin wavy (hence sinuans), the base running down the stem, with sharp teeth pointing forwards, stiffly hairy below, the border fringed with hairs. The stem-leaf is solitary, lance-shaped, acute, or bract-like, toothed. The 3-7 heads are large, dark, pitcher-like or bell-shaped, on long, straight, woolly-felted, glandular, stiffly hairy stalks. The phyllaries meet together in bud, and are very dark, the outer short, loose, the inner narrow, linear, lance-shaped, acute, with a pale margin, senescent, hairy, and glandular. The ligules are golden, stiffly hairy, the tips hairless. The styles are very dark. The plant is 6-15 in. in height, flowering in July and August, and is a herbaceous perennial.
