S ummarySilene maritima , a species that grows on coastal shingle and heavy‐metal‐contaminated mine spoils, was investigated to see whether these populations show any chromosomal differentiation. Karyotype studies do not reveal any difference between populations from metal‐free and metal‐contaminated habitats. Similarly, studies on the meiotic behaviour and pollen fertility of F 1 hybrids between plants from the two types of habitat show no indication of chromosome change accompanying the evolution of metal tolerance.
