Plants of Agrimonia striata with fruiting hypanthia campanulate or obconic or both occur throughout the range. Plants with vestiture more like that of A. gryposepala are sometimes found, particularly in Quebec and the mountains of Arizona and New Mexico.
Agrimonia eupatoria Linnaeus
Agrimonia eupatoria has been sporadically cultivated in the flora area. No evidence has been found that this introduced European species, which rarely escapes cultivation, has become an established element of the flora. It is distinguished from A. pubescens by the absence of tuberous roots, inflorescences with closely spaced, more or less subopposite flowers, and pendent fruiting hypanthia, 7–10 mm, covered with appressed hairs.
Agrimonia repens Linnaeus
Agrimonia repens has been reported (as A. odorata Miller) as persisting from cultivation on Prince Edward Island. There is as yet no evidence that this species is established; it can be identified by major leaflets more or less overlapping, mid cauline stipules 4–5 cm, petals 5–7 mm, and fruiting hypanthia cylindric with disc projecting 1.5 mm, 5–7 rows of circumferential bristles, proximal row reflexed.
