A description of Nabalus serpentarius is provided in The Flora of North America.
The inflorescence of this species is corymbiform to paniculiform, with 4-19 flowers per head. The flowers have 4-10 phyllaries that are sparsely setose and pubescent with long, coarse hairs. Its branches are well-developed and the principle leaves are evidently lobed.
This plant ranges from Massachusetts to Georgia, Panhandle Florida, and Mississippi.
In the Coastal Plain in Florida and Georgia, N. serpentarius can be found in longleaf pine-wiregrass flatwoods, beech magnolia woods, rich loam on steep slopes of wooded sinkhole ravines, rich mesic woodlands of shallow ravines, wooded ravine bottoms, dry woods, clay hillsides, clay loam in open stands, mixed pine-hardwood stands, open pine-oak woodlands, hardwood forest bluffs, drying loamy sand along mesic woodlands with limestone outcrops, subxeric woodlands on slopes of rivers, and frequently burned mature longleaf pine-wiregrass community. It can also be found along sidewalks.
N. serpentarius flowers from August through October.
Populations of Nabalus serpentarius have been known to persist through repeated annual burning.
