Chromosome studies on some Turkish species of Grimmia Hedw.: G-laevigata (Brid.) Brid., G-ovalis (Hedw.) Lindb., G-pulvinata (Hedw.) Sm., G-trichophylla Grev.

In this research, mitotic chromosome numbers in four species of Grimmia Hedw. from Turkey were reported. Mitotic chromosome numbers of three species : Grimmia laevigata (Brid.) Brid. (n = 26), Grimmia ovalis (Hedw.) Lindb. (n = 10), Grimmia pulvinata (Hedw.) Sm. (n = 26) were reported for the first time. Grimmia trichophylla Grev. (n = 13) showed the same chromosome number as in a previous study. (C) 2001 Adac/Editions scientifiques et medicales Elsevier SAS
