Chromosome Studies on Some Turkish Mosses

Mitotic chromosome numbers in sixteen species belonging to various genera from Turkey are reported. Mitotic chromosome numbers of five species: Pottia starkeana (Hedw.) C. Muell. (n = 26), B. cylindrica (Tayl.) Schimp. (n = 13 + 1 m), Bryum pendulum (Hornsch.) Schimp. (n = 20), Metaneckera menziesii (Hook.) Steere (n = 8), Pterigynandrum filiforme Hedw. (n = 11) were reported for the first time. Tortella tortuosa (Hedw.) Limpr. (n = 13) , Barbula convoluta Hedw. (n = 13), B. rigidula (Hedw.) Mitt. (n = 13), Pleurochaete squarrosa (Brid.) Lindb. (n = 13), Ceratodon purpureus (Hedw.) Brid. (n = 13), Pterogonium gracile (Hedw.) Sm. (n = 11), Homalothecium sericeum (Hedw.) Brunch, Schimp. & Gümbel (n = 10), Hypnum cupressiforme Hedw. (n = 10) showed the same chromosome number as in a previous study. Bartramia stricta Brid. (n = 8), Fissidens bryoides Hedw. (n = 12), Leucodon sciuroides (Hedw.) Schwaegr. (n = 10) showed the different chromosome number from in a previous mitotic study.
