Distribution | Mostly Piedmont, scattered in a few montane counties.
NC to TN, south to FL and AL. | |
Abundance | Uncommon in most of the range in the Piedmont, and rare in the Mountains. | |
Habitat | Dry to mesic woodlands and forest openings, clearings, clearcuts, roadside banks, fields, pastures | |
Phenology | Flowering and fruiting late June-September. | |
Identification | Plants grow mostly 3-5 feet tall, with lance-shaped to ovate leaves and a rather small inflorescence of nearly erect branches terminating in yellow heads. Basal leaves are absent at flowering time. The involucral bracts (surrounding each head) are broad, rounded, and thick-textured; thus they differ strongly from bracts of sunflowers (Helianthus).S. asteriscus and S. dentatum have rough surfaces to leaves (vs. smooth in S. asteriscus var. latifolium). Variety asteriscus has tiny hairs on the pales (tiny bracts at the base of each disk floret), but these lack glands (vs. glandular-hairy in S. dentatum). | |
Taxonomic Comments | Most NC specimens were annotated by J.A. Clevinger in 1999, who studied this species complex. Weakley (2020) pulled this taxon back out of the S. asteriscus complex. Note that in most of the 20th Century, this taxon -- S. dentatum -- had been considered as a good species.
