Diversity and Distribution Patterns of Aspleniaceae in Brazil

The family Aspleniaceae is represented in Brazil by two genera: Asplenium, with 69 species and four varieties and Antigramma, with three species. The genus Asplenium is widely distributed in the tropical and subtropical regions and presents 20 species that occur exclusively in Brazil. The genus Antigramma is mainly Neotropical, represented in this region by three species, one of them restricted to Brazil. The pantropical elements constitute 9.2%, the widely distributed in America 32.9%, the widely distributed in South America 4%, the restricted to the northern part of South America 11,8%, and those restricted to the meridional part of South America 11.8%. Species restricted to Brazil correspond to 27.6%, and are centered exclusively in the South and Southeastern regions. Two species (2.7%) represent disjunctions, one also occurring in the Andes and the other in the Guaianas. An analysis of the group in relation to the Neotropical fern diversity and speciation centers indicates that the majority of the taxa (78%) occur in she Southeastern Brazilian center. The Andean center presents significant relations with the Brazilian fern flora, followed by elements from the Guaianas and Mexico/Central America. The results reaffirm the importance of South-Southeastern Brazil as a major center of speciation and endemism for Neotropical ferns, especially the regions of the Atlantic forest and “campos rupestres” (rupestrial grasslands). Distribution maps of some species are presented with a discussion of the distribution patterns.
