Hieracium longiberbe (hi-er-ay-shium: hawk—; lawn-jib-er-be: long beard)
Flower heads bright yellow, several, ½–1″ across [12–25 mm]; no disk flowers; leaves alternate, 1–5″ long [3–12 cm], oblanceolate, 3–5 times longer than they are wide, entire; involucres, stems, and leaves (at least near edges) covered with long white hairs; leaf veins and stems often magenta in spring; stems milky-juiced, 10–24″ tall [25–60 cm].
Similar: Scouler’s Hawkweed, with mid-stem leaves much smaller than the basal ones, is widespread in the Northwest, but not as common within the Columbia Gorge.
Habitat: Rocky slopes at low elevations in the Columbia River Gorge.
