Juncus secundus Palisot de Beauvois ex Poiret. Subgenus: Agathryon. Section: Steirochloa. Common name: Secund Rush, Lop-sided Rush. Phenology: Jun-Oct. Habitat: Dry woodlands and fields, rock outcrops. Distribution: ME to IN, south to n. GA, c. AL, n. LA, and s. OK. Reports from the Coastal Plain of AL and MS are false, based on misidentification of J. dichotomus.

ID notes: Among section Steirochloa, J. secundus has individual flowers on short branches, and flowers borne secund along the branches of the inflorescence. This gives the flowers a more erect look in the field and is quite distinct among the section. The capsules are completely 3-locular, which can be seen in the field with a hand lens.

Origin/Endemic status: Native
