We have occasionally seen one to several mature fruit with an elongated narrowly campanulate hypanthium on an herbarium specimen or on a plant cultivated in the garden at Northern Illinois University. An achene was lacking in these fruit, the ovary having aborted. We have not observed in any other Agrimonia species the formation of apparently mature fruit with an atypical hypanthium shape and that lacked an achene.
Agrimonia parviflora is accurately and easily identified by mid-cauline leaves with 9-13 narrowly elliptic major leaflets usually with an acuminate apex that give it a distinctive appearance. Vegetative material of those infrequent plants of A. parviflora with only acute major leaflets might be mistaken for A. pubescens, but is distinguished by the presence of numerous sessile, glistening glandular hairs on the leaflet abaxial surface.
