A revision of Agrimonia (Rosaceae) in North and Central America

We conducted a morphological study of the Agrimonia species of North and Central America to clarify species limits and facilitate identification. We recognize eight species:A. parviflora, A. incisa, A. microcarpa, A. pubescens, A. rostellata, A. gryposepala, A. pringlei, and A. striata. A key for identification as well as descriptions of the recognized taxa with a discussion of the nomenclature and discriminating morphological characters are presented. Lectotypes are designated for A. parviflora, A. suaveolens, A. serrifolia, A. incisa, A. pumila, A. parviflora DC non Aiton, A. eupatoria δ parviflora, and A. striata. A lectotype and an epitype are designated for A. platycarpa. A neotype is designated for A. rostellata.
