4. Agrimonia rostellata Wallr. (woodland agrimony)

Pl. 523 j, k; Map 2404

Roots fibrous mixed with tuberous-thickened. Stems 25–70(–100) cm long, glandular and sparsely pubescent with short, ascending and long, spreading hairs, especially toward the base. Leaves 3–20 cm long, the primary (larger) leaflets 3–9, these 1.5–10.0 cm long, mostly elliptic to broadly elliptic or obovate, narrowed or tapered to a bluntly or sharply pointed tip, the margins with mostly relatively blunt teeth, the upper surface glabrous or nearly so, the undersurface glandular (sometimes sparsely so) and often also sparsely pubescent with short, appressed and long, spreading hairs along the veins. Inflorescence axis glandular (sometimes sparsely so) and usually also with sparse to moderate, short, ascending hairs toward the base (rarely only glandular), occasionally also with sparse, longer, spreading hairs, but these 1 mm or shorter, mostly shorter than the width of the axis at the attachment point. Stamens 10–15. Hypanthium at fruiting 2.0–2.5 mm long (fruits 3.5–4.5 mm long, including the beak), often only faintly grooved, glandular but otherwise glabrous. July–September.

Scattered nearly throughout the state, but apparently absent from portions of the Glaciated Plains Division (eastern U.S. west to Minnesota and Texas). Bottomland forests, mesic to dry upland forests, savannas, margins of glades, ledges and tops of bluffs, and banks of streams.

See the treatment of A. gryposepala for comments on difficulties in distinguishing A. rostellata from that species.
