Vernacular names
English: Fireweeds, Burnweeds

Erechtites is a genus of flowering plants in the daisy family known commonly as fireweeds or burnweeds. They are native to the Americas and Australia,[3][4] but some species are widely distributed weeds.[3][5][6]

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.[7][8] For the purposes of the list below, we follow the lead of The Plant List maintained by Kew Gardens in London.[1]

Erechtites consists of annual or perennial herbs with large taproots and very often with a pungent odor. Leaves are usually ovate or lanceolate (sometimes pinnately lobed or pinnatifid). Flower heads may sometimes contain as many as 100 yellow or white (rarely pink) disc florets but no ray florets.[3]

Species[1]

Erechtites glomeratus (Desf. ex Poir.) DC. - Australia[9]
Erechtites goyazensis (Gardner) Cabrera - South America
Erechtites hieraciifolius (L.) Raf. ex DC. - North America, South America, West Indies, Australia, New Zealand; naturalized in Asia[10][11]
Erechtites ignobilis Baker - Brazil
Erechtites leptanthus (Phil.) Cabrera - Chile
Erechtites minimus (Poir.) DC. - Australia[12]
Erechtites missionis Malme - South America
Erechtites runcinatus (Less.) DC. - Mexico
Erechtites valerianifolius (Wolf) DC. - Mexico, South America, Central America

The genus name Erechtites is considered masculine by some botanists and feminine by others. Hence some species names may end in "-us" or "-a," for example, Erechtites valerianifolius versus E. valerianifolia. International Code of Botanical Nomenclature (Art. 62.4) specifies that generic names ending in "-ites" are to be treated as masculine, hence the "-us" ending in such cases is to be preferred over the "-a" ending.[3][13]
