“…Dyckia limae and Tillandsia catimbauensis are restricted to the Park and represented by just a few irregularly distributed populations in the area (Fabricante et al 2014). Those authors reported that due to their extents of occurrence and areas of occupation, both species were classified as critically endangered (CR) according the criteria of IUCN (2010).…”

Specimens of phanerogamic plants from the Catimbau National Park, located in northeastern Brazil, were collected during extensive fieldwork and analyzed together with information gathered from the specialized literature. A total of 613 species was recorded, belonging to 366 genera and 85 families. The largest families were Fabaceae, Poaceae, Euphorbiaceae, Asteraceae, Convolvulaceae, Malvaceae, Myrtaceae, Apocynaceae, Malpighiaceae, and Cyperaceae, comprising almost 60% of the species. The level of endemism found was below that projected in the literature, as only four known species are unique to the study area. The area is, however, home to a varied flora with high richness and numerous rare or threatened species, demonstrating the importance of the National Park for conserving the regional flora. Additionally, 34 new registrations are reported here for Pernambuco State.

In the Atlantic Rainforest located north of the São Francisco River (northeast Brazil), the humid enclaves called brejos de altitude play a significant role in the diversity dynamics of local flora and fauna. The related species Dyckia pernambucana and D. limae (Bromeliaceae) are characterized by their narrow endemic occurrence in such brejos, and their species status remains unclear. In order to understand the species delimitation in those assigned taxonomic entities, patterns of gene flow and genetic variability were calculated using nuclear and plastid microsatellites and AFLP markers. In this regard, we collected populations of the Pernambuco complex (D. limae and D. pernambucana, from the Borborema Plateau) and the closest relative D. dissitiflora (from the northern Espinhaço Range). Genetic diversity was moderate, despite the possible influence of genetic drift and selfing rates. Dyckia limae could not be undoubtedly discriminated from the remaining populations of Pernambuco, and we propose the synonymization of these species. Thus, the conservation of D. limae as a formerly single species would not reflect the conservation of the minimal gene pool of the studied lineage (D. pernambucana). We also propose the revalidation of the conservation status of this species, endemic to anthropomorphic island-like mountains environments. Finally, the associations found here were consistent with the historical patterns of colonization and fragmentation of the Atlantic Rainforest.
