Sporophylls abruptly tapering toward apex; apex often recurved. Mostly on dry, exposed sand dunes, white sand, or sandy soil; 0 m; Fla., Ga. Selaginella arenicola subsp. arenicola usually has more slender (1 mm diam.) stems than subsp. riddelli (stems more than 1 mm diam.). In Georgia, many forms intermediate between the two subspecies have been reported.
