Inflorescences 1-flowered; peduncle sparsely hispid or glabrous; involucral-bracts 3, 1-tiered, simple, ±similar to terminal leaflets of basal leaves, ovate, rarely rhombic, (2.5-) 4-8 cm, bases distinct, broadly cuneate, margins crenate to serrate, or dentate on distal 2/3, apex acuminate, surfaces usually glabrous; lateral leaves unlobed or occasionally 1×-lobed; ultimate lobes 8-15 mm wide. Flowers: sepals usually 5, white, ovate to obovate, rarely oblanceolate, (12-) 15-25 × (8-) 10-15 (-20) mm, glabrous; stamens 100-120. Heads of achenes spheric; pedicel (5-) 7-12 cm. Achenes: body ovoid, swollen, 2.5-4 × 2-3 mm, not winged, proximally hispid, distally glabrous; beak straight to subulate, 0.5 mm or less, glabrous. 2n=14.

Discussion

Reports of Anemone deltoidea in British Columbia are erroneous (H.J. Scoggan 1978-1979, vol. 3).

Rhizomes 7m long and about 2 mm in diameter have been observed in Anemone deltoidea.
