O litoral do Piauí apresenta duas formações geológicas distintas: áreas assentadas sobre areias
quartzosas do Quaternário e a Formação Barreiras do Terciário. Este estudo apresenta a composição
florística de tabuleiro litorâneo situado no município de Cajueiro da Praia (PI), além de dados relacionados
aos fatores abióticos para região. Foram comparados os dados sobre a vegetação da região com áreas de
restingas subjacentes. O estudo apresenta uma da lista de 73 espécies, pertencentes a 33 famílias botânicas,
classificadas de acordo com o Sistema APG III.

The vegetation of the Brazilian restinga (coastal woodland) presents a variety of species and different characteristics,
encompassing fields, fruit groves and forests on quartzarenic neosols. We hypothesised that the structure of the
restinga landscape along the coast of the state of Piauí is influenced by edaphic factors and presents a pattern similar
to that of other northeastern restingas. We evaluated three restingas in Piauí, using the quarter method to determine
their structure. Composite soil samples were collected to determine their chemical and physical properties. Edaphic
variables were correlated with plant species by canonical correspondence analysis (CCA). Phytosociological data for all
three areas indicated regenerating vegetation comprising several small individuals, 82.5% of which showed a diameter
at ground level ≤ 13 cm. We also observed considerable tillering. In two of the areas, there was a predominance of
Fabaceae species, such as Caesalpinia pyramidalis and Copaifera martii. Although the structural characteristics of the
restingas studied were similar to those of other northeastern restingas, the former showed lower Shannon diversity
indices (2.18-2.44). The CCA indicated that species distribution was influenced by edaphic factors such as pH, aluminium content and amount of organic matter. The restingas studied were similar to others along the Brazilian coast.

Sandy coastal plain (Restinga) vegetation is composed of the plant communities that grow on Quaternary Neosols along the entire Brazilian coast. Ceará state has a coastal extension of 578 km and lies totally within the semi-arid
zone of northeastern Brazil. Here we present a checklist of the phanerogamic species found along the coast of Ceará that
was compiled from surveys and collections found at the EAC herbarium (Fortaleza, Ceará). A total of 391 species  distributed among 208 genera and 41 families were identified. The families with the greatest numbers of species were Fabaceae senso latu (130 species), Cyperaceae (51), Poaceae (47), Rubiaceae (27), Euphorbiaceae (19), Asteraceae (13), Bignoniaceae (11) and Malvaceae (12), representing over 78.77% of the species collected.
