    Femald (1938) recognized Agrimonia striata var. campanulata as distinguished by thinner and distinctly blunt leaflets and more or less campanulate fruiting hypanthia with rounded bases and occurring in the southern Rockies into Mexico. He distinguished the typical A. striata, which he cited as occurring from Newfoundland into New Mexico, by firmer leaflets with long acuminate to acute leaflet tips and cuneately turbinate fruiting hypanthia. Our examination of A. striata specimens suggested that although plants within the variety campanulata can be more frequent in the southwest both morphs and their intermediates occur across the entire range. The variation in leaflet and fruit shapes is also similar to the variation in these characters in other Agrimonia species. Thus, we recognize A. striata as a variable species without infraspecific taxa.

    In his treatment of Agrimonia, Hooker (1832) cited specimens collected by Richard- son and Drummond as examples of A. eupatoria. At K we could find only one specimen collected by Richardson in Canada. All of the Drummond Agrimonia collections housed there were collected in the southeastern United States. We therefore selected the specimen collected by Richardson as the lectotype for A. eupatoria sensu W. J. Hooker non L. non Torr.

    Bicknell (1896) mistakenly believed Agrimonia striata Michx. was synonymous with the species we recognize as A. rostellata Wallr. He therefore described a new species A. brittoniana for the American taxon earlier described by Michaux. In his description he cites (p. 519) type specimens collected at York Harbor, Maine, now housed at NY. Bicknell clearly marked the three sheets of the type collection with the note "type" on one sheet and "part of type" on the two others

    Agrimonia striata is distinguished by stipules nearly entire to proximally incised, usually rhombic major leaflets with acuminate apex, and flowers more or less sub-opposite along the inflorescence rachis. The deeply sulcate mature fruiting hypanthium can only occasionally be confused with that of A. pubescens. Some plants of A. gryposepala and occasional plants of A. pubescens have rhombic leaflets similar to those ofA. striata. Those plants of A. striata with acute major leaflet apices could be mistaken for plants of A. gryposepala or A. pubescens. A. pubescens usually lacks sessile, glistening glandular hairs, while A. gryposepala is merely hirsute. Both these species have flowers mostly alternate along the inflorescence rachis and stipules incised along the entire margin.

    As a corollary to his examination of Michaux's specimen of Agrimonia striata at P, Robinson (1900) identifies A. striata and A. pilosa Lebed, as conspecific, and concluded that A. striata should be accepted based on priority for the latter species in Europe. Rumyantsev during his doctoral work at the Moscow Main botanical Garden made a chemotaxonomic study of Agrimonia ser. Pilosae Skalicky (1971). From this work he concluded that A. striata and A. Pilosa are conspecific (personal communication to G. Kline). If this work was published, we have been unable to locate it.

  • Distribution

    Agrimonia striata occurs in thickets and deciduous or mixed deciduous woods in southern Canada from Newfoundland to British Columbia to ele- vations of 1300 m, in the northern United States extending into the mountains of West Virginia up to 1300 m and southward in the Rocky Mountains between 1200 and 3700 m, in the San Bemrnardino and White Mouof California and into the mountains of Mexico at 200-2500 m elevation
