Publication: Mongr. Amer. Sp. Polygonum. 132, plate 53. 1895.

Origin: Native

selected vouchers: WTU

Notes: FNA5: "C. L. Hitchcock (1964) suggested that Polygonum nuttallii is but a small-flowered form of P. spergulariiforme. Although morphologically similar, P. nuttallii differs from P. spergulariiforme in some respects, including its wiry, purplish stems, short and funnelform ocreae, adaxially glaucous leaves, longer bracts, shorter fruiting perianth, and achenes."
