Habitat: Mostly on granite outcrops, granite boulders, or gravelly or sandy soil
Elevation: 0–200 m
Distribution
Ala., Ark., Ga., La., Okla., Tex.
Discussion
The specimens of Selaginella arenicola subsp. riddellii from Texas are more constant in their morphologic characteristics and thus more easily separated from subsp. arenicola.
