Michael J. Oldham, Ian D. Macdonald

Abstract


Tall Annual Willowherb (Epilobium brachycarpum C. Presl) is reported from Dryden, Kenora District, Ontario, Canada, based on a 2012 collection from a disturbed habitat where the species was presumably introduced. This is the first northern Ontario record of E. brachycarpum and the first Ontario record in more than 40 years. Previous Ontario records are discussed and mapped, and evidence for and against native status in the province is presented. Identification characteristics are provided, and distribution and habitat elsewhere in North America are discussed.
