Chamaenerion Séguier. Subfamily: Onagroideae. Tribe: Epilobieae. Common name: Fireweed.

A genus of 8 species (9 taxa), herbs, of arctic, boreal, and temperate Northern Hemisphere. There is increasingly strong evidence for the recognition of this group of plants as a genus separate from Epilobium. Its name has been controversial (see synonymy); see Sennikov (2011) for a detailed summary.
