| Publ. & Syn. | Pulsatilla hirsutissima (Pursh) Britton, Ann. New York Acad. Sci. 6: 217 (1891) [nom. illeg.]. - Pulsatilla patens subsp. hirsutissima (Pursh) Zamelis, Acta Horti Bot. Univ. Latv. 1: 98 (1926) [nom. illeg.]. - Anemone ludoviciana Nutt., Gen. N. Amer. Pl. 2: 20 (1818) [nom. superfl. and illeg.]. - Pulsatilla ludoviciana (Nutt.) A. Heller, Cat. N. Amer. Pl., ed. 2: 4 (1900) [nom. illeg.]. |
| Notes | The name Pulsatilla hirsutissima is illegitimate because the given basionym is Clematis hirsutissima Pursh, Fl. Amer. Sept. 2: 385 (1813), a true Clematis. The names Anemone ludoviciana and Pulsatilla ludoviciana are also illegitimate as nomina nova for Clematis hirsutissima. |
