Hieracium Curvatum, Elfstrand

The habitat of this plant is Highland mountains, where it occurs on granite, mica schist, and hornblende. The plant is green. The stem is stiffly hairy, woolly-felted, glandular, especially above. The radical leaves are bright-green, coarsely toothed, spoon-shaped, the later elliptic, oblong, rounded above, narrowed to the leaf-stalk, the inner inversely lance-shaped, acute, with acute teeth below, sparsely hairy both sides. The lower stem-leaves are lance-shaped, acute, shortly-stalked, with acute teeth, the upper 2-3, linear, bract-like. The heads, usually solitary or 2-3, are very dark, large, rounded below, on long arching stalks, when branched, woolly-felted, hairy, glandular. The phyllaries meet together in the bud, the outer loose, linear, lance-shaped, blunt, the inner with a long, narrow point, 2-3 innermost awl-like, shaggy, hairy, scarcely glandular. The ligules are orange, the teeth fringed with hairs or smooth. The styles are brownish. The plant is variable in height, flowering in July and August, and is a herbaceous perennial.

Hieracium Backhoitsei, F. T. Hanb. - The habitat of this plant is lofty mountains, crevices of rocky beds and margins of mountain streams, stony shores of alpine lakes. The stem is dark-green, wavy, with long, white, spreading hairs, stellately downy and glandular above. The radical leaves are erect, deep-green, leathery, glossy, rounded to spoon-shaped, inversely egg-shaped, the apex rounded, narrowed to the foot-stalk, the latter oblong, lance-shaped, the inner lance-shaped, linear, acute, with acute, ascending, curved teeth below. There are 1-3 stem-leaves. The lower are stalkless, narrow, lance-shaped, acute, sharply toothed, the upper linear, bract-like, the leaves smooth above, stiffly hairy below, especially on the margin. The heads are dark, 1-3, rounded below, the stalks long, straight, woolly-felted, glandular. The outer phyllaries are linear, loose, the inner linear, lance-shaped, blunt, the innermost narrow, acute, clothed with hair, without glands. The ligules are yellow, stiffly hairy. The style is yellow or livid. The pappus is tawny. The plant is 5-15 in. in height, flowering in July and August, and is a herbaceous perennial.

Hieracium Lingulatum, Backh

The habitat of this plant is mountain glens, rocky beds of mountain streams, and in their debris, grassy ledges, exposed cliffs. The plant is green, with a stiffly hairy, woolly-felted (above hairy), glandular stem. The radical leaves are deep dull-green, leathery, with fine teeth, the outer inversely egg-shaped, rounded above, the inner tongue-shaped (hence lingulatum), lance-shaped,acute, narrowed,rough, hairy, above and below, and on the border. The stem-leaves are 2-3, the lower nearly stalkless, like the lower inner leaves, the upper leaves very small. The 2-4 heads are rounded below, with woolly-felted glandular stalks. The phyllaries extend forwards in bud, and are linear, acute, greenish-black, oblong, narrow above, hairy, glandular. The ligules are smooth or fringed with hairs. The styles are dark, livid. The plant is 15-24 in. in height, flowering in July and August, and is a herbaceous perennial.
