False dandelion


Agoseris glauca is a perennial herb having a large taproot and can grow from 8–50 cm tall. It has linear to oblanceolate leaves, 3–35 cm long, the margins are entire or with 1 to 3 pairs of shallow lobes. Stems and leaves are glabrous to sparsely villous. Flowers appear in a terminal head on a long scape with an involucre that is 1–2 cm long; phyllaries linear-lanceolate to lanceolate, in 2 to 3 indistinct series, green, glabrous to villous, sometimes glandular, often darkened along the midvein. Heads contain 15 to 150 flowers that are all ligulate, yellow, the ligules 6–22 mm long and each floret having a pappus 8–18 mm long. The fruit is an achene, with a body that is 4–9 mm long with a beak ranging from 0.5–3 mm long.
