This annual plant with a wide, almost cosmopolitan distribution, is present in all regions of Italy with the exception of Molise, but is generally quite rare. It grows in rather disturbed habitats, on moist soil, from sea level to about 1200 m. It is a characteristic species of the Mediterranean temporary ponds, cited in the IUCN regional Red List as an endangered species (Conti et al., 1997). In Sardinia it is very rare on the edge of the ponds. The genus name is an anagram of Gnaphalium the genus from which the species has been separated; the species name in Latin means 'white-yellowish', in reference to the dense hairiness of the plant and its yellow flowers. Flowering period: June to September. Syn.: Gnaphalium luteo-album L., Pseudognaphalium luteoalbum (L.) Hilliard & B.L. Burtt
