Twelve moss species belonging to two families, Meteoriaceae and Neckeraceae, were studied karyologically. Metaphase and heteropycnotic chromosomes in mitotic cells of gametophyte were observed. The chromosome numbers and karyotypic formulae were determined as follows:
Meteorium helmintocladulum K(n)=10=V(H)+V+J+6(5v+j)+m(h)
M. helminthocladum K(n)=10=V(H)+V+J+6(5v+j)+m(h)
Chroysocladium retrorsum K(n)=11=2V(H)+2V+2J+4(2v+2j)+m(h)
Barbella asperifolia K(n)=10=V(H)+2V+2J+4v+m(h)
Pseudobarbella levieri K(n)=11=V(H)+2V+2J+5(4v+j)+m(h)
Floribundaria floribunda K(n)=11=V(H)+V+J+7(4v+3j)+m(h)
Neckeropsis calcicola K(n)=10=V(H)+2V+J+5(3v+2j)+v(h)
N. nitidula K(n)=10=V(H)+2V+J+5(3v+2j)+v(h)
Homaliodendron scalpellifolium K(n)=10=V(H)+3V+J+4(3v+j)+m(h)
Homaliadelphus targionianus K(n)=10=V(H)+3V+J+4(3v+j)+v(h)
Thamnium plicatulum K(n)=11=V(H)+3V+J+5(4v+j)+m(h)
T. sandei var. cumbifolium K(n)=11=V(H)+3V+J+5(4v+j)+m(h)
