This genus also belongs to the Everlasting group, but it differs from all the preceding genera in having scales or bracteoles on the receptacle between the florets, and quadrangular achenes crowned with a membranous cup-like pappus. There are only two species, both Australian. The name is from auuos, sandy sea-shore, and Bios, life, in allusion to the habitat of the following species.
