DistributionThe sole specimen at SERNEC is one from "Eastern North Carolina" by G. McCarthy in 1885 (herbarium MO). Thus, it is listed by the NCNHP as SR (reported), but the specimen needs a careful ID check. Weakley (2020) states that Riggins (1977) reports this species from NC in his revision of the Sporobolus asper group, but it is not clear whether the report is based on McCarthy's specimen or not.
IdentificationIn the field it resembles S. clandestinus, but lemmas are glabrous (vs. pubescent).
Taxonomic CommentsFormerly known as S. asper.

Recent molecular research suggests that Calamovilfa and Spartina are nested deeply within Sporobolus. Weakley (2020) proposes that they remain split until a long-term solution is found, as their members are monophyletic.
