Phenology: Flowering (spring–)May–Dec.
Habitat: Sandy and gravelly soils, coastal dunes, disturbed ground, roadsides, vacant lots, fields, areas in pine and oak woods and scrub
Elevation: 0–100+ m

Discussion
Subspecies subaxillaris is found on the outer coastal plains along the Gulf and Atlantic coasts from northern Mexico to Delaware. They are rarely more than 1 m and can be procumbent on dunes. Atypical spring-blooming plants often lack the distinctive distal tuft of coarse hairs on the phyllaries. The number of hairs in the tuft decreases from as many as 28 in Texas and Louisiana to 10–15 in Florida to 6–16 from Georgia to New Jersey.
Selected References
None.
Lower Taxa
