Results of research and eco-coenotic and chorological features of synanthropic species of the genus Linum in the flora of Ukraine: L. trigynum, L. bienne (hemiapophytes), L. nodiflorum, L. corymbulosum (eventapophytes), L. usitatissimum (ergasiophyte). These species are characterized by wide ecological amplitudes; by their relation to soil humidity most species are hemistenotopic submesophytes, to soil humidity variance – hemieurytopic hemihydrocontrastophiles, to soil acidity – hemistenotopic neutrophiles, and to soil aeration – stenotopic subaerophiles. In relation to the general salt regime of soil, hemistenotopic eutrophic species predominate; to the carbonate content in soil – hemistenotopic acarbonatophiles, to the assimilable nitrogen content in the soil – hemistenotopic heminitrophiles. The leading coenotic group is asectators (not dominants nor subdominants) confined mainly to disturbed ecotopes in mixed segetal-and-ruderal communities. The studied species belong to the Mediterranean geoelement type that includes Eastern Mediterranean (L. bienne, L. corymbulosum, L. nodiflorum) and Mediterranean (L. trigynum) geoelements.
