Carex brizoides, the quaking sedge or quaking-grass sedge, is a species in the genus Carex, native to central and southern Europe. [2] Even where it is a native species, in disturbed woodlands it tends to behave invasively, forming a thick layer on the forest floor and reducing species diversity. [3] [4]

Carex interior is a species of sedge known by the common name inland sedge. It is native to much of North America from Alaska to northern Mexico to the mid-Atlantic United States.

Carex firma forms thick cushions. Its leaves are up to 8 centimetres (3.1 in) long in normal conditions (up to 10 cm or 4 in in moist, sheltered localities), dark green and stiff. [ 1 ] The stems are up to 20 cm (7.9 in) tall (exceptionally 30 cm or 12 in), but always at least twice as long as the leaves.
