The habitat of this plant is sub-alpine glens. The stem is wiry, hollow, simple or branched, finely furrowed, reddish, stiffly hairy below, woolly-felted, glandular above. The radical leaves are dull deep-green, bluish-green, with prominent veins below, membranous, the outer withering early, oval, blunt-pointed, toothed, the intermediate egg-shaped, lance-shaped, wedge-shaped below, toothed, the innermost narrower, the point triangular, the base narrow, toothed, nearly smooth below, stiffly hairy below on the nerves, the margins fringed with hairs. The 2-3 stem-leaves have stalks (the lower) like the inner basal, the upper stalkless, toothed. The panicle bears few flowers, with 2-3 erect branches, the upper close, bent in, longer than the acladium. The flower-stalks are straight or curved above, woolly-felted, glandular, stiffly hairy. The heads are short, medium, rounded below. The phyllaries are awl-like, blunt, the inner acute, woolly-felted at the edge, senescent, glandular, hairy. The ligules are hairless. The styles are dull or livid. The margins of the receptacle pits are toothed. The plant is 1-2 1/2 ft. high, flowering from June to August, and is a herbaceous perennial.
The stem of this species is tall, slender, wavy, stiffly hairy, glandular above. The radical leaves are dull-green, with brown to purple blotches, 3-4, forming a rosette, on long stalks, egg-shaped to oval, oblong, blunt, toothed, the base egg-shaped or wedge-shaped, toothed, the inner lance-shaped to elliptic, narrow, toothed, stiffly hairy, woolly-felted below. The 1-3 stem-leaves are lance-shaped, toothed, or entire. The panicle has 1-2 lower branches erect to spreading, the upper close, erect to spreading, bent inwards. The flower-stalks are straight, unequal, long, slender, paired, the upper longer than the short-stalked acladium, woolly-felted, glandular, hairy. The 3-8 heads are long, blackish-green, conical at length. The phyllaries extend outwards, are narrow, linear to lance-shaped, blunt, the inner with a green border, tipped with purple, the innermost rather acute, glandular, hairy. The ligules are hairless. The styles are yellow, discoloured.
Hieracium anfractiforme; E. S. Marshall. - The habitat of this plant is rocky sub-alpine streamlets, on granite and mica-schist. The stem is rigid, hollow, hairless, woolly-felted, glandular above. The radical leaves are firm, bright-green, bluish green, the outer narrow, inversely egg-shaped or lance-shaped, blunt, the base wedge-shaped, finely toothed, the inner lance-shaped, linear, acute, narrow below, toothed, running down the leafstalk, stiffly hairy below, fringed with hairs on the margin. The stem-leaf is stalked, narrow to lance-shaped, acute, toothed. The panicle has a straight base with curving branches, longer than the short-stalked acladium. The stalks are nearly straight, woolly-felted, hairy. The 1-4 heads are cylindrical in bud, bell-shaped in flower. The phyllaries are dark, linear to lance-shaped, narrow below, blunt, with a pale border, woolly-felted, senescent, hairy, glandular. The ligules are golden, fringed with hairs. The styles are livid. The achenes are chestnut.
Hieracium dissimile, Lindeb. fil. - The habitat of this plant is mountain glens. The stem is round, tinged with purple, wavy, stiffly hairy, woolly - felted, hairy above. The outer radical leaves form a rosette, and are inversely egg-shaped to spoon-shaped, with a round apex, wedge-shaped below, the margin toothed, the inner elliptic to lance-shaped, narrowed both ends, toothed, hairy below and on the margins. The stem-leaves are 1-3, like the last. The panicle is small, nearly simple, or corymbose, with 2-3 erect to spreading, arching branches, longer than the acladium. The stalks are woolly-felted, stiffly hairy, glandular. The 4-8 heads are thick, egg-shaped. The phyllaries are oblong to linear, narrow above, blunt, the inner acute, with a pale border, woolly-felted, senescent, hairy, glandular. The ligules are yellow, tipped with stiff hairs. The styles are dingy. The plant is 10-18 in. high, flowering in July and August, and is a herbaceous perennial.
