Species Plantarum 2: 927 ) in Latin〕〔(Linnaeus, Carl von. 1753. Species Plantarum 2: 1199 ) addendum in Latin〕〔(Tropicos, Filago L. )〕〔(Altervista Flora Italiana, genere ''Filago'' ) includes photos, drawings, + distribution maps〕 The name cudweed comes from the fact that they were once used to feed cows that had lost the ability to chew the cud.〔(Wild Flowers Of the British Isles Website )〕 Several species are sometimes treated as members of genus ''Logfia''. ==Description== They bear woolly, cottony heads of flowers. They have narrow strap-shaped untoothed leaves. The flower heads are small,gathered into dense, stalkless clusters.
