To the north it is found to England and south-eastern Sweden. In Central Europe it has no continuous area of ​​distribution and is absent in places all over, such as in Northern Germany. Despite their relative rarity, they may occur at their locations with a large number of copies.

In Austria it occurs on dry and semi- dry grassland and dry scrub hemming in the Pannonian area frequently in the rest area scattered to very rare. The deposits are confined to the provinces of Vienna, Lower Austria, Burgenland, Carinthia and Upper Austria.

The first publication of this species comes from Carl Linnaeus under the name chrysocoma linosyris in Species Plantarum, 2, 1753, p 841 The name Galatella linosyris (L.) Rchb.f. in 1853 by Heinrich Gustav Reichenbach in Icones Florae Germanicae et Helveticae ..., 16, p 8 released. Other synonyms for Galatella linosyris (L.) Rchb. f are: Aster liburnicus ( Spreng. ) Rouy, Aster savii Arcang, chrysocoma liburnica Spreng, chrysocoma linosyris L., chrysocoma nupera Gray, chrysocoma palustris Savi ex Bertol chrysocoma palustris Savi, chrysocoma vulgaris Güldenst. .. . ex Ledeb. , Crinitaria linosyris subsp. armoricana ( Rouy ) Holub, Crinitina linosyris (L.) Soják, Deinosmos siculus Raf., Erigeron linosyris Clairv. , Galatella pontica ( Lipsky ) Novopokr. & Bogdan, linosyris vulgaris DC ..

The gold button is still widely by the scientific name Aster linosyris (L.) Bernh. known. However, it was separated from the genus Aster. They can be found now under the name Galatella linosyris (L.) Rchb.f. or narrower version of the generic term as Crinitaria linosyris (L.) Less ..
