Perennial herb from a short, stout rhizome; stems erect, branched above, solitary or several, glabrous or nearly glabrous below, with starlike hairs above and often with some short, stout, subconic hairs in the inflorescence, rarely with long, spreading hairs, exuding milky juice when broken, 0.4-1.2 cm tall.
Basal and lower stem leaves small, soon deciduous at flowering time; middle stem leaves lanceolate to narrowly oblong, unstalked, often narrowed to the base, 6-10 cm long, 1-2 cm wide, entire to somewhat toothed, with starlike hairs and subconic, more or less rough, stiff hairs on the margins and veins above; upper leaves reduced.
Achenes nerved, 3-3.5 mm long; pappus tawny.
Of the two subspecies recognized within Hieracium umbellatum, only the spp. umbellatum occurs in our range. The ssp. canadense (Michx.) Guppy (H. canadense Michx.) occurs east of the Rocky Mountains (Guppy 1978).
