Discussion

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.
