The 558 km range extension of the Amazonian aroid Dracontium nivosum (Lem.) G.H.Zhu into semiarid Northeast Brazil is confirmed. This species occurs in Cear\á in threatened fragments of brejo forest at ca. 580\–870 m elevation. An illustrated taxonomic description is provided. The species\’ Extent of Occurrence (EOO) is estimated as 356,392 km2 (meets Least Concern); the Area of Occupancy (AOO), 60 km2 using a 2\×2 km cell (Endangered). Within Cear\á the EOO is 41.4 km2 (Critically Endangered) and the AOO is 16 km2 (Endangered).

Sandy coastal plain vegetation (Restinga) is composed of communities of plants that grow on Quaternary Neosols along the entire extension of the Brazilian coast. The state of Piau\í has a coastal extension of 66 km and is entirely located in the semi-arid zone of Northeastern Brazil. This study catalogued the phanerogam species found along the coast of the state of Piau\í, the data of which was compiled from surveys in online databases and literature, and herbarium collections. A total of 363 species distributed among 235 genera, and 74 families were identified. The families with the greatest number of species included Fabaceae (108 species), Euphorbiaceae (19), Amaranthaceae (13), Apocynaceae (12), Cyperaceae (12), Rubiaceae (12), Bignoniaceae (11), Malvaceae (11) and Poaceae (11) and represent over 57.6\% of the species collected. Approximately 87\% of the species were common to other restinga areas in Northeastern Brazil, and ca. 13\% were restricted to the coast of the state of Piau\í.

Sandy coastal plain (Restinga) vegetation is composed of the plant communities that grow on Quaternary Neosols along the entire Brazilian coast. Cear\á 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 Cear\á that
was compiled from surveys and collections found at the EAC herbarium (Fortaleza, Cear\á). 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.

In this study, we present new records of
Faramea nitida that extend the range of this species in
Maranh\ão state, Brazil. The new data were the result
of fieldwork by us in restinga areas of S\ão Jos\é de
Ribamar and Alc\ântara districts. This report highlights
the rediscovery of a species after many years (30 to 70
years) and shows the necessity for more floristic and
taxonomic studies on extreme northeastern Brazil.
