Diagnostic Characteristics:
Very similar to other members of the section Laxiflorae, especially C. laxiflora, which occurs in similar habitats. One distinguishing feature is that it has an obtuse angled perigynia which is nearly to completely nerveless, while most of the other Laxiflorae are strongly nerved. This a tufted deep green plant with brown basal sheaths. Terminal spike is staminate. The perigynia tapers to the base, is 2-ribbed, and obscurely 3-sided.

Timber removal would be detrimental. Disturbance of surrounding areas 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.
