America and Asia were reported. The karyotypes belong to 1A or 2A types and their formulae are: 24m+4sm(2sat) (for E. canadensis); 20m+8sm(4sat) (E. elymoides); 20m+8sm(4sat) (E. glaucus); 22m+6sm(4sat) (E. lanceolatus); 22m+6sm(2sat) (E. mutabilis); 22m+6sm(2sat) (E. sibiricus); 24m+4sm (E. trachycaulus); 22m+4sm+2st(2sat) (E. trachycaulus ssp. subsecundus); 24m+4sm(4sat) (E. virginicus); and 20m+8sm(4sat) (E. wawawaiensis).
