Diagnostic Characteristics:
This species is distinguished from other species of Fimbristylis by the following characters: Leaves are linear (flat) and more than 1mm wide. Involucral bracts few and shorter than inflorescence. Styles are bifid and the stamens are usually 3 and 2-3 mm long (rather than fewer and shorter in F. annua). It is tall (up to 1 m) compared to other species. It occurs as solitary stems or small tufts and the leaves are scabrous on the margins. All species are associated with wet places.

Woody plant invasion may need to be controlled using periodic prescribed fire, mowing or other means. Timber removal may be beneficial. Hand removal of trees in the vicinity is needed to maintain the open character of the habitat for this species. Soil disturbance such as ATV trails or timber removal or any activity that results in increased erosion and weed invasion will be detrimental. Exotic pest plants are a threat to this species and should be removed.
