Perennial herb from a short, often stout rhizome; stems erect, simple or sometimes branched, few to several, sparsely to moderately short or long soft-hairy, sometimes sparsely glandular-hairy above, exuding milky juice when broken, 3-45 cm tall.
Basal leaves persistent, tufted, narrowly elliptic, 1-16 cm long, 0.4-3.0 cm wide, entire or nearly so; stem leaves few or lacking, reduced, bractlike.
Heads with strap-shaped flowers, solitary or several; involucres 5-10 mm tall; involucral bracts linear-lanceolate, subequal, greyish, long soft-hairy, without glandular hairs; ray flowers yellow.
Achenes nerved, 2-3 mm long; pappus tawny or sometimes white.
Easily confused with H. gracile which has glandular-tipped hairs on the stalks of the heads and involucres.
