1. Agrimonia gryposepala Wallr. (tall agrimony, hooked agrimony)

Pl. 523 d, e; Map 2401

Roots all fibrous. Stems 30–150 cm long, glandular and sparsely to densely pubescent with long, spreading hairs. Leaves 6–30 cm long, the primary (larger) leaflets (3–)5–9, these 3.0–11.5 cm long, elliptic or obovate to broadly elliptic or ovate-lanceolate, mostly tapered to a sharply pointed tip, the margins with mostly relatively blunt teeth, the upper surface glabrous or with sparse, long, spreading hairs, the undersurface glandular and with sparse to moderate, short, appressed hairs, especially along the veins, sometimes also with a few longer, spreading hairs. Inflorescence axis glandular and also pubescent with sparse to moderately long, spreading hairs, these mostly more than 1 mm long, longer than the width of the axis at the attachment point. Stamens mostly 15. Hypanthium at fruiting 3–5 mm long (fruits 6–8 mm long, including the beak), deeply grooved, glandular, sometimes also sparsely hairy toward the base along the ridges. 2n=28. July–September.

Uncommon in the Glaciated Plains Division with a disjunct occurrence in Douglas County (U.S., except some western and southern states; Canada). Mesic to dry upland forests, upland prairies, savannas, and banks of streams.

Immature specimens of A. gryposepala can be difficult to separate from A. rostellata. In general, plants of A. rostellata tend to have more slender stems and somewhat smaller, narrower, more delicate leaves than does A. gryposepala, but there is too much overlap in these quantitative features to allow their incorporation into a key.
