Inflorescences cymose, 15–50 × 10–30 cm; branches glabrous or villous; bracts 3, semileaflike, linear, and 5–30 × 2–5 mm proximally, scalelike, triangular, and 1–4 mm distally. Peduncles absent or slender, erect, 0.5–4 cm, glabrous or tomentose. Involucres 1 per node or 2–5 per cluster, turbinate, (2.5–) 3–4 × 2.5–3 mm, glabrous or slightly tomentose; teeth 5, erect, 0.4–0.9 mm. Flowers 2.5–4 mm, glabrous; perianth white; tepals connate proximal 1/4, monomorphic, obovate; stamens exserted, 2.5–4 mm; filaments pilose proximally. Achenes light-brown, 3.5–4 mm, glabrous.

Discussion

Varieties 2 (2 in the flora).

Eriogonum elatum is widely distributed but rather scattered throughout its range. The plants are occasionally seen in the garden. Inflorescence branches were chewed or made into an infusion and taken as a physic by some Native American people (D. E. Moerman 1986).
