Sipulinurmikka Halikossa - vakiintunut uustulokas vai arkeofyytti?

Is Poa bulbosa an established neophyte or an archaeophyte in Halikko, south-western Finlad?The origin of Poa bulbosa L., a rare grass in Halikko, Salo, south-western Finland (Varsinais-Suomi), is examined in relation to other known localities of the species in Finland and Sweden. Poa bulbosa is considered a neophyte in Finland, but descriptions of the species habitats in e.g. Sweden suggest that it could just as well be an archaeophyte in Halikko. The surrounding grassland community in Halikko includes both archaeophytes and apophytes common to dry grasslands on shallow soils, such as Arabidopsis suecica, Galium verum, Geranium pusillum, Sedum acre, Sedum telephium, Trifolium arvense and Veronica verna.
