Solidago gracillima Torrey & A. Gray. Phen: Aug-Oct. Hab: Wet pine savannas, seepage bogs. Dist: E. NC south to c. Panhandle FL, west to s. AL.
Origin/Endemic status: Endemic
Taxonomy Comments: Several distinct entities appear to have been referred to this taxon; the number of entities, and the appropriate names to apply to them, are presently obscure. The names S. perlonga Fernald, S. austrina Small, and S. simulans Fernald have been synonymized under S. gracillima (as by Cronquist 1980). Cronquist (1980) refers material from WV and high elevation granitic domes of sw. NC (S. simulans) to S. gracillima, a treatment which is not phytogeographically or otherwise credible. The distinction between S. gracillima s.s. and S. austrina seems to be warranted; they are alleged to differ as follows: S. austrina: pappus 2.2-2.8 mm long, ray flowers 2-4, disc flowers 6-8; of the inner Coastal Plain and lower Piedmont; S. gracillima: pappus (3.0-) 3.5-4.0 mm long; ray flowers 3-7; disk flowers 9-13; of the Coastal Plain.
