The name cudweed comes from the fact that they were once used to feed cows that had lost the ability to chew the cud.[7]

Several species are sometimes treated as members of the genus Logfia.

Description

edit

They bear woolly, cottony heads of flowers. They have narrow strap-shaped untoothed leaves. The flower heads are small, gathered into dense, stalkless clusters. The fruits have a hairy pappus,[8] or modified calyx, the part of an individual disk, ray or ligule floret surrounding the base of the corolla, in flower heads of the plant family Asteraceae.
