Asteraceae : Erigeron pumilis

Erigeron pumilus is a taprooted perennial with a simple to branched caudex with ascending to erect stems, 5–30 cm tall covered with long, spreading hairs, many of which are glandular toward the top. The basal and alternate cauline leaves are simple, entire, the blades are linear- to narrowly oblanceolate, 15–80 mm long and up to 8 mm wide. The inflorescence is a cluster of heads (1-many) that are 7-15 mm in diameter. The involucre is 4–8 mm high, the bracts in 2 to 4 series, with minutely glandular hairs and a brownish midvein. Each head has 50–100 white to pinkish (occasionally bluish) ray flowers, the ligules 5–12 mm long. Corollas of the disk flowers are yellow and 2–5 mm long. Achenes are 1–2 mm long with a pappus of 2 rows of bristles. Shaggy fleabane blooms from June into August on dry high plains and prairies predominantly in west river South Dakota.
