Distribution
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, H. subaxillaris occurs in open sand with sea oats, pine-scrub oak sand ridges, longleaf pine-wiregrass savannas, and upper beaches. It has been found in disturbed areas such as railroad bridges, powerline corridors, vacant lots, along highways, wet roadside ditches, near phosphate ponds, fire lines, and cleared sand pine-evergreen oak scrub (FSU Herbarium). Soil types include loamy sand and sand (FSU Herbarium). Associated species include Andropogon, Baccharis, Setaria, Cenchrus, Distichlis, Paspalum urvillei, P. notatum, Eragrostis oxylepis, Eleusine indica, Digitaria sanguinalis, Cyperus surinamensis, Ambrosia artemisiifolia, Strophostyles helvola, Solanum americanum, S. sisymbrifolium, Daubentonia drummondii, and Sesbania exaltata (FSU Herbarium).
