Nabalus barbatus, the barbed rattlesnakeroot,[2] is a plant in the family Asteraceae. It is native to the Southeastern United States where it is found in small numbers in a few disjunct areas of remaining natural grassland. Because of this, it is considered a globally rare species, with only 35-70 remaining populations. Much of its natural habitat of prairie and savanna has been destroyed.[1] In 2010 it was reclassified from the genus Prenanthes to Nabalus.[3]
It is a perennial that flowers in early fall, [4] although flowering has been reported into November.[5]
Habitat
[edit]The natural habitat of this species is prairie and savanna.[1] It is known from rich hardwood and pine-oak forest as well as mesic ravine slope forest in the pineywoods of east Texas.[5]
Range
[edit]This species occurs from Oklahoma, Arkansas, and Kentucky south from Texas to Georgia.[1] It occurs in nine counties in central and southeast Arkansas[6] and in 13 counties in the eastern four counties of Texas.[5]
