Erechtites Atkinsoniae
''Erechtites'' is a genus of flowering plants in the Asteraceae, daisy family known commonly as fireweeds or burnweeds. They are native to the Americas and Australia, but some species are widely distributed weeds. Description ''Erechtites'' consists of Annual plant, annual or Perennial plant, perennial herbs with large taproots and very often with a pungent odor. Leaves are usually Leaf shape, ovate or lanceolate (sometimes Leaf shape, pinnately lobed or pinnatifid). Flower heads may sometimes contain as many as 100 yellow or white (rarely pink) disc florets but no ray florets. Taxonomy and species Some species in this genus are treated as members of ''Senecio'' by some authors, and several other species are considered variants of ''Erechtites hieraciifolius'', so there may be as few as 5 distinct species in this genus. In particular, not all authors agree on whether to include a dozen or so species native to Australia and New Zealand in ''Erechtites''. ;Species 27 species ar ...

Erechtites Hieraciifolius
''Erechtites hieraciifolius'' (fireweed, American burnweed, or pilewort) is a plant in the daisy family, Asteraceae.
