    Notes: Abstract Populations ofAgrostis Tenuis andFestuca rubra, tolerant and non-tolerant towards Zn and Pb, were studied in regard to their adaptability by natural selection, towards a third metal (Cu) and the time required for the appearance of such tolerance. It was found that Zn and Pb tolerant and non-tolerant populations are likely to select the character of Cu-tolerance within the course of only one generation. More specifically, Zn and Pb tolerant populations show a better adaptability compared with non-tolerant ones. The amount of tolerance to copper obtained by artificial selection is comparable with that of populations growing naturally on copper mines.

    Notes: Abstract A native population ofAegilops cylindrica was encountered for the first time in Greece in 1980 (near Kastoria, NW. Greece), completely isolated and at a great distance from its main distribution area. There are morphological and chromosomal, but no protein and esterase pattern differences from otherAe. cylindrica populations. This justifies the recognition of a new variety: var.kastorianum. Our comparative and karyotypic observations support the view thatAe. caudata var.polyathera and not var.caudata (typica) is the possible donor of genome C of the new variety.
