Diagnostic Characteristics:
This rush has a terminal inflorescence, the bracts foliaceous (not stiff). The plant is more than 20 cm tall, and the tepals (the petals and sepals are merged into one structure) are yellowish with a green midstripe. The flowers do not have a subtending (beneath or at the base) bract. The glomerules are spherical and there are less than 10 per stem. This is a species found associated with glade habitats.

Management:
Woody plant invasion may need to be controlled using periodic prescribed fire, mowing or other means to maintain the open character of the habitat for this species. Hand removal of trees in the vicinity of the species is necessary. Soil disturbance resulting from activities such as ATV trails, 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.
