DistributionRanges over the southwestern third of the Coastal Plain, from the Sandhills region southeast to the coast, ranging north to Moore, Harnett, and Pender counties.

This is a Southeastern species with a fairly small range. It occurs from southeastern NC south to southern FL, but is not known from AL or states to the west.
AbundanceInfrequent to locally fairly common. Scarce in the Sandhills proper. Not as numerous as might be expected in NC. The NCNHP's State Rank of S2S3 is reasonably accurate, though S3 is possibly better.
HabitatThis is a species of sandy soil, and usually very xeric sites. It grows in Sand Barrens, Coastal Fringe Sandhills, Xeric Sandhill Scrub, and other similar natural communities. Easiest seen, and locally common, on xeric sandrims of Carolina bays.

PhenologyFruits from June to August.
IdentificationThis is a wiry, somewhat decumbent plant with multiple finger-like branches, somewhat ascending and forming a rounded clump 6 inches or more across, but reaching only about 1.5 inches high. The plant is gray-green, covered densely by scale-like leaves with acuminate tips, looking quite moss-like. The strobilus (reproductive structure) is generally erect and about 2/5-inch long. The other two native NC species in the genus grow on rocks, in the Mountains and Piedmont.
Taxonomic CommentsFormerly named in most references as Selaginella arenicola.
