    The study aimed to conduct a floristic survey and describe the phytophysiognomies present in the region of the Marituba do Peixe APA, located on the southern coast of the state of Alagoas. The work aimed to identify the species that make up the local vegetation and to describe the phytophysiognomies. To carry out this study, geographic data and samples from the region deposited in the herbarium collections were analyzed, in addition to collections made in remnants of the study area. The research resulted in obtaining data on the vegetation and phytogeography of the region, including species habits, distribution, phytophysiognomonic types, conservation level, and the record of endemic and endangered species. For the floristic listing, 397 species were recorded, distributed in 104 botanical families. The most representative families were Fabaceae (41 species), Rubiaceae (21 species), Myrtaceae and Cyperaceae (20 species each). Among the cataloged species, 43 are new records for the state of Alagoas, while 13 species are categorized as threatened. Several taxa are endemic to the Northeast region. All the data identified demonstrate the importance of conserving the study area for the protection of these plants.

    Flora de Alagoas: Paullinia L.(Sapindaceae)
    (Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-05-27) Souza, Maria Helena Nascimento de; Freire, Genise Vieira; Correia, Maria Lausanne Damasceno; http://lattes.cnpq.br/6602158987512253; Alves, Karina Dias; http://lattes.cnpq.br/2899542504433422
    Sapindaceae is a family with great diversity, with approximately 1900 species, being widely distributed in tropical and subtropical climates. In Brazil, there are 436 species and 26 genera, with high endemism in the Atlantic and Amazon forests. Regarding the genus Paullinia L., object of the present study, it is included in Sapindaceae and currently comprises 220 species, being one of the largest groups of the family, differing mainly by the diverse morphology of its capsule fruits. The study was carried out in the state of Alagoas, located in the northeast region, which has its vegetation distributed in three mesoregions: East, Agreste and Sertão Alagoano. The main objective of this study was to elaborate the Flora de Paullinia for the state of Alagoas, enriching the knowledge about the Sapindaceae family and the flora of the state. To carry out this work, collections were carried out in several regions of the state of Alagoas, analyzes of herborized materials deposited in the MAC herbarium, in addition to consultation in virtual herbariums of Reflora, JABOT and Specieslink. Ten species were recognized for the genus at the study site: Paullinia carpopoda Cambess., P. elegans Cambess., P. micrantha Cambess., P. pinnata L., P. pseudota Radlk, P. revoluta Radlk., P. rhomboidea Radlk., P. rubiginosa Cambess., P. trigonia Vell. and P. weinmanniifolia Mart. Identification key, descriptions, geographic distribution, illustrations and taxonomic comments for the species are presented.
