Sporobolus curtissii (Vasey ex Beal) Small ex Lamson-Scribner. Phen: Jul-Nov. Hab: Moist, gummy-clay pine flatwoods. Dist: E. SC south to c. FL. Attributions of S. curtissii to NC and SC prior to 1993 were apparently based on misapplication or confusion with S. teretifolius and/or Sporobolus pinetorum.
ID notes:Sporobolus curtissii differs from other ‘bunchgrass’ Sporobolus of our area in having the spikelets short-pedicelled and appressed against the panicle branches (as opposed to long-pedicelled and spreading in S. teretifolius and Sporobolus pinetorum).
