39b. Solidago stricta Aiton subsp. gracillima (Torrey & A. Gray) Semple, Sida. 20: 1615. 2003.

Solidago gracillima Torrey & A. Gray, Fl. N. Amer. 2: 215. 1842; Aster gracillimus (Torrey & A. Gray) Kuntze; S. austrina Small; S. perlonga Fernald

Basal leaves sparsely to obviously serrate. Arrays sometimes with much elongate proximal arching branches. 2n = 18, 36.

Flowering Aug–Oct. Swamps, boggy depressions, and other moist places, blackish sandy muck, sometimes dry sandy soils, mostly inner coastal plain; 20–300 m; Ala., Fla., Ga., N.C., S.C., Va.

Subspecies gracillima occurs away from the coast to the edge of the piedmont and usually has arching proximal array branches, several of which can be greatly elongated. Some plants from Alabama, Georgia, and the Carolinas treated as Solidago austrina are included here, but may deserve recognition as a variety. Solidago perlonga appears to belong in this subspecies: its arrays would be very aberrant if included in the typical subspecies.
