Abstract

New localities of Eragrostis albensis H. Scholz and Dittrichia graveolens (L.) Greuter have been found in the southern Poland. The former taxon is currently considered a kenophyte (epecophyte and holoagriophyte) in the country. It occurs on sandy alluvia along Vistula, Oder and San River Valleys as well as on anthropogenic sites mainly in the eastern and south-eastern Poland. The latter species is a recent newcomer regarded as an ephemerophyte, which so far has been reported from only one locality in Śląskie Province. In 2017 we discovered 16 new localities of E. albensis and five of D. graveolens on the territory of the southern Poland. Populations of both species consisted of few to several dozen individuals which grew within anthropogenic habitats, mainly roadsides. Distribution maps of both species in the southern Poland were presented.

Abstract

Arabis recta Vill. is a therophyte currently considered to be endangered in Poland (EN category). The species has been reported from ca. 20 localities situated mainly in the Nida Basin (southeastern Poland). Arabis recta is usually a component of xero-thermophile grasslands, but it can also grow in arable fields or fallows. An abundant population of A. recta was found on slopes of the Góra Sosnówka hill (Małopolska Upland) in 2017. This newly discovered locality is currently the northernmost in Poland. The distribution of A. recta in Poland as well as collected phytosociological documentation are presented.
