Chromosome numbers in some mosses from western Canada

Abstract

Chromosome numbers are reported for six moss species from western Canada, four from British Columbia, two from Alberta. These give data on chromosome numbers from new localities in Canada for populations of five species and the first record for Kiaeria starkei from Canada. Chromosome numbers reported are n = 13, Grimmia afftnis; n = 14, Kiaeria starkei; n = 14 (13 + m), Dicranum scoparium; n = 20, Bryum pseudotriquetrum; n = 11, Ptilium crista-castrensis; and n = 6, Hypnum circinale.
