Stipulicida filiformis Nash; S. setacea var. filiformis (Nash) D. B. Ward

Sepals with margins ± entire, outer sepals with apex acute to obtuse.

Flowering spring-fall. Dry, sandy soil of pinelands, scrub, fields; 0-200 m; Ala., Fla., Ga., La., Miss., N.C., S.C., Va.

We follow W. S. Judd (1983) in considering Stipulicida filiformis, described to account for plants with fewer flowers and thinner stems, as a morphological/ecological extreme of S. setacea; for an alternative view, see D. B. Ward (2001).
