Some former species

Formerly included

Numerous species have at one time been included in Gnaphalium, [3] but are now considered to belong to other genera: Achyrocline, Aliella, Ammobium, Anaphalioides, Anaphalis, Anaxeton, Antennaria, Argyrotegium, Belloa, Berroa, Blumea, Castroviejoa, Chevreulia, Chionolaena, Chrysocephalum, Dolichothrix, Edmondia, Euchiton, Ewartia, Facelis, Filago, Galeomma, Gamochaeta, Gnomophalium, Helichrysum, Ifloga, Laphangium, Lasiopogon, Leontonyx, Leontopodium, Leucogenes, Logfia, Lucilia, Luciliocline, Metalasia, Micropsis, Neojeffreya, Novenia, Ozothamnus, Pentzia, Petalacte, Phagnalon, Pilosella, Plecostachys, Pseudognaphalium, Pterocaulon, Rhodanthe, Raoulia, Schizogyne, Staehelina, Stuckertiella, Syncarpha, Troglophyton, Vellereophyton, Xerochrysum

Secondary metabolites

Gnaphalium species are known to contain flavonoids and diterpenes. Recently, two unique caffeoyl-D-glucaric acid derivatives, leontopodic acid and leontopodic acid B formerly only known from Leontopodium alpinum (L.) Cass. were detected in various species of Gnaphalium together with similar formerly unknown compounds. [6]
