Nabalus crepidineus, commonly called the nodding rattlesnakeroot,[1] is a species of flowering plant in the family Asteraceae. It is native to the United States , where it is found in the Midwest and Upland South regions.[2] Its natural habitat is in bottomland and mesic forests, and along streambanks.[3]
Description
It is a perennial flowering plant growing up to 3 m (9.8 ft) tall. It produces white (sometimes yellow) flowers in late summer and autumn.[4][3] It is most easily seen in the spring, where it can forms large colonies of sterile basal rosettes. These rosettes are typically epehemeral, with proportionally very few persisting beyond mid-summer into the flowering period.[3]
Molecular and morphological evidence indicates that Nabalus crepidineus and its North American relatives are best treated in a separate genus from Prenanthes. This treatment became widely adopted in the 2010s.[5][6]
N. crepidineus is most often seen as only basal leaves
Range
This plant occurs from western New York west to southeastern tip of Minnesota, south to Arkansas and Tennessee.[2] Although widespread, it is considered infrequent throughout its range.[7]
In Arkansas, this species occurs in 12 counties, mostly in the Arkansas Ozarks.[8]
