About Agrimonia pubescens Wallr.
Agrimonia pubescens Wallr. is an erect perennial herb that can grow over 40 inches (1,000 millimeters) tall. Its stems are erect and covered in fine, short soft hairs (canescent or pubescent). Each compound leaf holds 5 to 13 leaflets; these leaflets are oblong, toothed along the edges, and pinnately divided a single time. The overall compound leaf has a lanceolate shape, with the terminal leaflet being the largest, ranging 1.25–4 inches (32–102 mm) in length and 0.5–2 inches (13–51 mm) in width. Leaflets get larger as they grow closer to the tip of the compound leaf. At the base of each leaf stalk (petiole) there is an oval-shaped stipule with a serrated margin, measuring approximately 0.75 inches (19 mm) long and 0.38 inches (9.7 mm) wide. Yellow flowers of this species grow on spike-like racemes. Each individual flower is 0.25–0.33 inches (6.4–8.4 mm) wide, with five yellow petals and five to ten stamens. The five sepals are sparsely covered in fine hairs, and alternate in position with the petals. Both the small flowers and the conical fruit of Agrimonia pubescens have short stalks (pedicels). Its seeds bear hook-like projections and are clustered in a bell-shaped arrangement. When fruiting, the hairless (glabrous) calyx measures 0.08 inches (2.0 mm). This plant flowers from July through September. It occurs predominantly in the United States, east of the Mississippi River.
