Scleria ciliata Michaux var. glabra (Chapman) Fairey. Smooth Nutrush. Hab: Pine savannas and pine flatwoods. Dist: E. NC south to s. FL, west to e. TX.

Origin/Endemic status: Endemic

Taxonomy Comments: Plants with minor to moderate amounts of pubescence on culms and leaves are frequent in some areas, and not readily assignable to either S. ciliata var. ciliata or var. glabra. Glabrous/glabrate plants are more common on the outer Coastal Plain. S. ciliata var. curtissii (Britton) Kessler (=S. pauciflora Muhl. ex Willd. var. curtissii (Britton) Fairey) is currently of uncertain taxonomic standing. It is distinguished by its reticulate, non-papillose achenes, but such a condition has been observed in achenes with the hypogynium lobing of both S. ciliata and S. pauciflora (as suggested by the synonymy), and may only represent a form or condition.
