Leaves: stipules of basal leaves simple, lanceolate, margins entire, those of cauline lanceolate to ovate, coarsely serrate; petiole longer than blade in basal and proximal cauline leaves, to shorter than proximal rachis segment in distal cauline ones; leaflets 2–12 pairs, proximally alternate, subopposite, or opposite, distally subopposite or opposite, margins coarsely serrate, surfaces glabrous or sparsely pilose. Spikes subglobose to ovoid, 0.3–2.5 × 0.3–2 cm; peduncles glabrous or sparsely loosely villous; bracteoles ovate, equal to hypanthia, ciliate. Flowers generally gynomonoecious, bisexual flowers proximal and pistillate distal (rarely some spikes completely pistillate or completely bisexual); hypanthium broadly ellipsoid; sepals green to purple, margins scarious, apex acute to apiculate with tufts of trichomes; filaments filiform, equal to sepals. Achenes enclosed within broadly ellipsoid hypanthia 4 mm, 4-sided, angles winged, surfaces irregularly reticulately ridged, ridges sometimes also muricate. 2n = 28, 56.
Phenology: Flowering May–Aug; fruiting Jul–Oct.
Habitat: Open disturbed areas, pastures, roadsides, woodland edges, along railroad rights-of-way, some preference for calcareous soil
Elevation: 0–2700 m

Discussion
All North American plants of Poterium belong to var. polygamum. This taxon has also been reported for New Brunswick; this is unconfirmed, but certainly plausible. Reports for North America of Sanguisorba minor or P. sanguisorba refer to that in a broad sense, not distinguishing the varieties or subspecies variously recognized, and do not imply the occurrence of the typical infrataxon in North America. It is possible that the typical variety (or other infrataxa, as defined in the European literature) is present in North America. The other infrataxa differ primarily in details of the ornamentation of the hypanthium, with either more or less pronounced wings, differences in the roundedness or acuteness of the wings, and variations in the reticulate patterns between the wings; refer to the European literature to identify material suspected of belonging to other infrataxa.
