- Common Wild Quinine
- Flora of Virginia Name/Status

- Variation in number of flower heads and leaf dimensions is the basis for two putative varieties in Virginia: var. integrifolium, and var. mabryanum Mears. Most Virginia plants are var. integrifolium, and the distinctiveness and status of var. mabryanum requires further study.
- Dry-mesic to dry, open forests, woodlands, barrens, and clearings; mostly on acidic to moderately basic soils. Frequent in the mountains (except sw. Virginia) and Piedmont; infrequent in the inner Coastal Plain. Var. mabryanum is alleged to occur infrequently in sandhill woodlands and sandy clearings of the se. Virginia Coastal Plain.
