Selaginella carnerosana

Selaginella carnerosana is a spikemoss described by Reeves in 1980 from the faces of limestone cliffs at Carneros, Coahuila, in the Chihuahuan Desert mountains of northeast Mexico. Like other cliff spikemosses of that region it almost certainly survives long droughts dried out. Grow it bright, open and gritty on limestone with wet-dry cycles, not in a closed terrarium.
