Muhlenbergia torreyana (J.A. Schultes) A.S. Hitchcock. Common name: Pinebarren Smokegrass. Phenology: Aug-Nov. Habitat: In the Coastal Plain in moist soils of depression meadows and clay-based Carolina bays, often under or near Taxodium ascendens, in the Interior Low Plateau and Cumberland Plateau in moist grassy oak savannas. Distribution: NJ to GA in the Coastal Plain, and disjunct in KY (?)and TN; currently known to be extant only in NJ, NC, and TN. It was first discovered in NC in 1987.
ID notes: Although it rarely flowers except following fire, it can be recognized in sterile condition by its forming clonal patches with evenly spaced, upright, blue-green tufts, each tuft a flattened stem with 5-10 ascending-erect, rather stiff, usually conduplicate leaves, the summit of each sheath with a pronounced cartilaginous thickening, easily felt by running the flattened stem from base to apex between thumb and forefinger.
