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.
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.
