On the floristic relationships between Cuba and other Tropical regions based on the distribution of CubanAsplenium L.species (Aspleniaceae, Pteridophyta)

[摘要] Based on the world distribution of the species ofAspleniumoccurring in Cuba, a presenceabsence matrix for 17 selected geographical áreas was constructed. This matrix was separately evaluated with the Similarity Index of Sorensen and Parsimony Analysis of Endemicity (PAE). The floristic relationships between Cuba and the rest of tropical regions are presented and discussed. Similar results were obtained using both methods. The closest relationships among the Greater Antilles islands were confirmed from the composition of their pteridological floras. The continental affinity of Greater Antilles flora was corroborated.
