Endemic
Basionym: Eriogonum greenei A. Gray Proc. Amer. Acad. Arts 12: 83. 1876
Synonyms: Eriogonum niveum var. greenei (A. Gray) S. Stokes
Treatment appears in FNA Volume 5. Treatment on page 318. Mentioned on page 317.

Plants dense mats, 2–10 dm wide. Leaf-blades ovate, 0.5–1 cm, densely white-lanate to tomentose on both surfaces. Inflorescences 3–5 cm; branches tomentose. Involucres 4–6 × 2–3 mm, tomentose. Flowers 4–5 mm; perianth white.


Phenology: Flowering Jun–Sep.

Discussion

Variety greenei is restricted to the North Coast Ranges of northwestern California (Humboldt, Mendocino, Siskiyou, Tehama, and Trinity counties). In the herbarium, it is occasionally difficult to distinguish from nonserpentine populations of var. proliferum. The variety is worthy of cultivation.
