Gnaphalium sect. Euchiton (Cass.) DC.

Euchiton is a genus of flowering plants in the daisy family. They are native to Australasia and the Pacific. Some have been introduced far outside their native ranges.[2]

These are annual and perennial herbs. Some have rhizomes, and most have stolons. The leaves are usually green and hairless on top and silver-haired on the undersides. Most have purple florets.[2][3]

The taxonomy of the genus is still unclear and is likely to change.[4] Several species were recently transferred into the new genus Argyrotegium, for example.[5][2]
