PhenologyFlowering and fruiting June-July.
IdentificationThis is a robust nutrush, having a stem up to 3 feet tall, from a thick, knotty, horizontal rhizome. The spikelets are in a terminal cluster, with a long erect bract that appears as a continuation of the stem. It is similar to Georgia Nutrush (S. georgiana), but is larger in almost all respects, including the seeds (3-4 mm long vs. 2-3 mm long in that species).
Taxonomic CommentsNone

The genus Scleria, named as nutrushes, is a group of sedges notable for the white, often glossy, achenes (seeds) and tough, knotty, horizontal rhizomes (absent in S. verticillata, S. muehlenbergii, and S. reticularis). Stems are 1-many per plant, terminated by inflorescences of 1-several spikelets, subtended by leafy bracts. In some species there are also inflorescences produced from upper and middle stem leaf axils, these usually on long arching stalks. A dissecting scope is necessary to examine the achene for shape, ornamentation (bumps, pits, ridges), and hairs. Just as important are features of the hypogonium, upon which the achene tightly sits: present or not, how many lobes, and ornamentation (bumps, sharp points, etc.).
