Abstract
ABSTRACT A previously described but unnamed hybrid of Geum aleppicum and G. canadense is reported from central New York, Vermont, and southern Ontario. Wild plants were compared to a cultivated plant and all exhibited traits intermediate in characters between the parent species. Comparative analysis of floral characters showed little relationship to Geum virginianum, as previously proposed. The hybrid is also compared to two similar hybrids involving G. urbanum, with which it might be confused. The hybrid is described and named here as G. ×hainesianum, nothosp. nov. A key to Geum species and hybrids east of the Rocky Mountains is presented.
