|discussion=<p>Subspecies ramosissimum is heterogeneous; some additional elements may deserve recognition. It is closely related to European <i>Polygonum</i> bellardii Allioni, which was collected in south Boston in 1785 (B. L. Robinson 1902). The latter species has semi-open flowers, petaloid tepals with white or pink margins, and eight stamens. A distinct form of <i>P. ramosissimum</i> growing in saline marshes from California has been mistakenly identified as <i>P. patulum</i> Bieberstein (M. Costea and F. J. Tardif 2003b). The morphology of late-season achenes and the branching patterns, which have been emphasized by some authors, appear to have little taxonomic value.</p>
