The perigynia of cedar sedge are kidney-shaped without ventral nerves. Causes of Decline Habitat destruction, in the form of wetland draining and timber harvesting, is a major factor in the decline of tissue sedge. Recovery Needs Clarification of possible ambiguities in the taxonomy of tissue sedge is needed. More data should be gathered regarding the life history of this species. Description Tissue sedge grows from thick, branching, black-fibrous rhizomes.
Blades are flat, stiff and light green.
Blades are absent from the plants lower leaves, but both sheaths and blades are present on the upper leaves. The lower sheaths are dark brown and tear into fibrous strips with age. Upper sheaths are white and have a tissue-paper appearance. Female flowers are placed above the male flowers on the spike. Fruits are lense-shaped achenes.
