POACEAE 915 Sacciolepis striata (Linnaeus) Nash, American Cupscale. Cp, Pd (GA, NC, SC, VA), Mt (GA, NC, SC): marshes, interdune swales, ditches, swamps; common (rare in Piedmont and Mountains). July-October. S. NJ south to FL, west to e. TX and OK, nearly limited to the Coastal Plain, but occasionally inland as in w. NC and TN; also native in the West Indies and n. South America. [= RAB, C, F, FNA, G, GW, HC, K, W] Schedonorus Palisot de Beauvois The correct generic placement of the introduced species Schedonorus arundinaceus (= Festuca elatior; = Festuca arundinacea; = Lolium arundinaceum) and Sch. pratense has been disputed. The traditional placement in Festuca has been defended by Aiken et al. (1997); Darbyshire (1993) transferred them to Lolium; and Soreng & Terrell (1998) place them in the genus Schedonorus. NOTE: apparently, the Soreng & Terrell (1998) paper was preceded by another paper which renders Soreng & Terrell's combinations superfluous.

POACEAE 916 Schizachyrium littorale (Nash) Bicknell, Seaside Little Bluestem. Cp (GA, NC, VA): coastal dunes and maritime dry grasslands, often with Uniola paniculata, Panicum amarum, and other dune plants; common. August-October. E. MA south to NC (or SC?), and inland on the shores of the Great Lakes. In NC, Sch. littorale is present and abundant on dunes of barrier islands from Shackleford Banks, Carteret County south to Brunswick County, near the SC border, and entirely absent from the Outer Banks (from Cape Lookout, Carteret County, north through Hyde County to Dare County).

One of the most ubiquitous plants in the modern landscape of our area, occurring throughout in the majority of habitats. This species is extremely variable, some of the variability correlated with habitat and geography; the recognition of infraspecific taxa is warranted.
