Erechtites glomeratus explained

Erechtites glomeratus, common name New Zealand fireweed, or cutleaf burnweed,^[1] or (in Australia) fireweed^[2] or Cluster-headed fireweed, is a species of plant in the sunflower family. It is native to Australia (all 6 states) and New Zealand, and also naturalized on the Pacific Coast of the United States (Washington, Oregon, and California).^{[3] [4] [5]}

The name accepted by Australian authorities is Senecio glomeratus,^{[6] [7] [8]} and this is also the name accepted by Plants of the World online.^[9] The name Erechtites glomeratus is considered by APNI to be illegal.

It was first described in 1817 by René Louiche Desfontaines as Senecio glomeratus, from a specimen cultivated in the Jardin des Plantes.^[10]
