Selaginella caluffii

Selaginella caluffii is a Cuban endemic spikemoss described in 2003. It is known from a handful of collections in central Cuba, around Topes de Collantes in the Escambray mountains and along streams. Little is published beyond the description, so grow it as a warm, shaded, streamside spikemoss.
