This association includes vegetation of field margins, fallows or open stands of cereal crops on nutrient-poor, sandy soils. It is dominated by low-growing annuals of oceanic distribution, most notably Arnoseris minima and Teesdalia nudicaulis. It is an endangered vegetation type currently found on a single site in the Třeboň Basin in southern Bohemia, although there were some historical localities in western Bohemia and the middle Labe area.
