Tall Rattlesnake-root
Prenanthes altissima L.
Flora of Virginia Name/Status
Nabalus altissimus (L.) Hook.
In 2012, we felt that the original molecular work suggesting that Prenanthes as traditionally circumscribed is polyphyletic was old and preliminary, and that additional studies including North American taxa were needed to confirm the relationships of Prenanthes and recognition of Nabalus at the genus level. More recently, additional studies have definitively supported the inclusion of North American Prenanthes in Nabalus. See Schilling et al. (2015, Phytoneuron 2015-19: 1–8).
In a wide range of mesic to dry upland forests, well-drained alluvial forests, and clearings. Common in the mountains and inner Piedmont; infrequent in the outer Piedmont and inner Coastal Plain.
