Eriogonum ochrocephalum var. ochrocephalum

James L. Reveal
Common names: White-woolly wild buckwheat
Treatment appears in FNA Volume 5. Treatment on page 283.

Leaf-blades oblanceolate to elliptic or ovate to obovate, 1–2 × (0.3–) 0.5–1 (–1.5) cm. Scapes 0.5–1.5 (–2) dm, glandular at least proximal to inflorescence. Involucres turbinate-campanulate to campanulate, 3–5 (–6) × 3–4.5 (–5) mm, sparsely to densely floccose, occasionally sparsely glandular. Flowers 2–2.5 (–3) mm; perianth glabrous or rarely weakly glandular. Achenes 1.5–2.5 mm.
