摘要：

Two new species and a new hybrid species of Selaginella (Lycophyta: Selaginellaceae), from Pinar del Rio and Artemisa Provinces in W Cuba, are described and illustrated. The new species are S. cavernaria, an erect plant growing on calcareous rocks and cliffs in mogote vegetation, and S. striata, a prostrate plant occurring in the same ecosystems and sometimes growing together with S. cavernaria. The new hybrid species is S. xdualis (S. serpens x S. striata), with intermediate morphology, growing together and sometimes mixed with the postulated parent species. All three new taxa are representatives of S. subg. Stachygynandrum.
