| Distribution | Mountains and upper Piedmont; disjunct to Brunswick and Jones counties in the lower Coastal Plain.
Southern VA to MO, south to northern FL and western LA. Scarce in the Atlantic Coastal Plain. | |
| Abundance | Fairly common to common in the Mountains; rare to uncommon in the western Piedmont, mainly in the foothills. Very rare in the lower Coastal Plain. | |
| Habitat | Woodlands, rock outcrops, forest slopes, wooded borders, and meadows. | |
| Phenology | Flowering and fruiting July-September. | |
| Identification | A leafy species, Star Tickseed grows 2-3 feet tall, with 8-11 pairs of elliptical leaves, usually pubescent. Some leaves may have a pair of lobes near the base of the blade. Heads are held erect on long stalks, rays yellow and with toothed tips, the disks orange-yellow. Differences between the two varieties in NC are based on amount of pubescence and leaf width; however, judging from the wide overlap in distribution and the difficulty in assigning a specimen to one variety or another, it seems that more research needs to be done. | |
| Taxonomic Comments | Weakley (2018) lists two varieties in the state -- var. pubescens and var. robusta.
For excellent drawings of all species (except those recently described) and range maps (although now out-of-date), see the monograph by Smith (1976). | |
