Common Name
White Rattlesnake-root
Prenanthes alba L.
Flora of Virginia Name/Status
Nabalus albus (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).
Mesic to dry-mesic upland forests. Widely distributed but rather infrequent in the mountains and inner Piedmont; rare in the outer Piedmont and Coastal Plain.
