Regularity: Regularly occurring
Global Range: North Carolina to Florida, west to Oklahoma and Texas, mostly on the coastal plain.
There are 3 spikemoss species in the southeastern US with leaves all of one size. S. arenicola's erect habit and gray-green color distinguish it from S. rupestris, and its clearly visible leaf midrib and straight rather than twisted bristle at the leaf apex distinguish it from S. tortipila.
Comments: scrub and scrubby flatwoods (Abrahamson & Hartnett 1990, Myers 1990); dry, sandy places and sandhills (Radford et al. 1968); sandy or gravelly places or in crevices of acidic rocks (Lellinger 1985); sandhills, dunes, and scrub (Clewell 1985).
Plants killed by fire, but species quickly reestablished from spores (not distinguished whether buried or dispersed in from outside burned area); abundance in rosemary scrub shows decrease with time since last fire (Menges & Kohfeldt, unpubl. 1994).
Life History and Behavior
Persistence: PERENNIAL, EVERGREEN
The genus Selaginella is sporophytic, with the sporangia each borne in the axil of a foliage leaf (sometimes modified), these leaves forming a cone or strobilus. Large megaspores (female) and small microspores (male) are produced in separate sporangia within one strobilus.
