Concept ReferenceKartesz, J.T. 1994. A synonymized checklist of the vascular flora of the United States, Canada, and Greenland. 2nd edition. 2 vols. Timber Press, Portland, OR.
Taxonomic CommentsName spelled 'hieraciifolia' in some reference (e.g., Kartesz, 1999), in accordance with ICBN Recc. 60G.1 (2000), but was originally spelled 'hieracifolius' [in Senecio] by Linnaeus, a usage maintained by Wagner et al. (1999). ICBN (2006) Article 62.4 suggests it should be corrected to 'hieraciifolius', a correction accepted in FNA (2006, vol. 20).

Rank ReasonsFireweed (Erechtites hieraciifolius) occurs throughout eastern North America (west to the eastern Great Plains), it occurs in southeastern Canada, the eastern United States, in most of the states of Mexico and in South America. It is adventive in western United States, western Canada and in Europe, Asia and New Zealand. It is estimated that there are more than 7500 occurrences within the native range, including in the United States on several National Parks, National Wildlife Refuges, various National Forests, and on many State Parks, State Forests and State Wildlife Management Areas.
Range Extent CommentsFireweed (Erechtites hieraciifolius) occurs throughout eastern North America (west to the eastern Great Plains), it occurs in southeastern Canada, the eastern United States, in most of the states of Mexico and in South America. It is adventive (not native) in some areas in western United States and western Canada, and in Europe, India, eastern Asia, and New Zealand. The native range extent was estimated to be 20 million square kilometers, using herbarium specimens and photo-based observations documented between 1993 and 2024 (FNA 2006, GBIF 2024, iNaturalist 2024, POWO 2024, Villaseñor 2016).
Occurrences CommentsBy applying a 1 km separation distance to herbarium records and photo-based observations documented between 1993 and 2024, it is estimated that there are more than 7500 occurrences within the native range extent (GBIF 2024, iNaturalist 2024).
Threat Impact CommentsResidential development may be a threat in some areas. While land clearing and development is in progress there may be an increase in numbers of plants, but when development is completed, there is a loss of habitat.
