| Distribution | Though this "new" species was split from the old Solidago stricta, as in RAB (1968), in reality it is a split of the newer S. gracillima. However, there is no consensus among botanists that Southern Goldenrod and Graceful Goldenrod (S. gracillima) are truly two distinct species or even varieties. Until the dust settles, it is best to lump the two, with the name S. gracillima having priority. See that name for a full species account. For the record, Weakley (2024) shows S. austrina as occurring in the Piedmont and Coastal Plain, with this species occurring more in "the inner Coastal Plain and lower Piedmont", whereas S. gracillima is present more generically in the Coastal Plain, and not into the Piedmont of NC. To be conservative, the editors have mapped just the specimens in SERNEC at NCU, as hopefully these have been well curated.
Weakley (2024) says of the overall range: "Sc. NC south to GA, Panhandle FL, and nw. AL, extending (as here interpreted) into TN and KY." | |
| Abundance | The website editors have moved the SRANK from the S2? ranked by NCNHP to a tentative S3? -- in brackets. The species has not yet been given a Global Rank by NatureServe. | |
| Habitat | Weakley (2024) suggests that this is an upland species, as opposed to S. gracillima, as he says for the first species: "Piedmont prairie remnants, openings in xeric hardpan forests, upland depressions, clay roadbanks and powerline rights-of-way, post oak savannas, and open oak-hickory woodlands"; whereas for S. gracillima has says "Wet pine savannas, seepage bogs". | |
| Phenology | See the Solidago gracillima account. | |
| Identification | See the Solidago gracillima account. For the record, Weakley (2024) says that S. austrina has "pappus 2.2-2.8 mm long, ray flowers 2-4, disc flowers 6-8", whereas S. gracillima has "pappus (3.0-) 3.5-4.0 mm long; ray flowers 3-7; disk flowers 9-13". | |
| Taxonomic Comments | See Distribution. The State Rank should perhaps be listed as [SYN?], though the editors are not quite ready to assign the entity as a Synonym -- invalid taxon -- just yet. In fact, Weakley (2020, 2024) does consider these two entities as valid species, providing several characters to separate the two.
