Abstract
The gametophytic chromosomes of 7 moss species belonging to 6 families were studied. Their chromosome complements are formulated as follows:
Andreaeaceae
Andreaea nivalis Hook. K(n)=10=V(H)+5V+2J+2J(h)
Splachnaceae
Tetraplodon mnioides (Hedw.) B.S.G. K(n)=8=2V(H)+3V+2J+J(h)
Cryphaceaceae
Cyptodontopsits obutusifolia (Nog.) Nog. K(n)=11=V(H)+6V+3J+J(h)
Pilotrichopsis dentata (Mitt.) Besch. K(n)=8=V(H)+3V+3J+J(h)
Myuriaceae
Eumiurium sinicum (Mitt.) Nog. K(n)=10=V(H)+6V+2J+J(h)
Neckeraceae
Homalia japonica Besch. K(n)=11=V(H)+5V+4J+J(h)
Hookeriaceae
Distichophyllum maebarae Besch. K(n)=10=2V(H)+5V+2J+J(h)
