Asteraceae in the Curimataú Ocidental microregion, Paraíba State, Brazil

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

Caatinga formations comprise the most important vegetation mosaic of the northeastern region. Asteraceae constitutes one of the five richest species families for this area, however, constantly neglected in floristic and taxonomic studies. The aim of this paper was to conduct a floristic survey of this group in the Curimataú Ocidental microregion, Paraíba State, which is considered an area with few information about its biodiversity, especially the flora. We based this study on monthly collections from April/2018 to September/2019 in the most diverse places of the area and consulting collections of the main herbaria of Paraíba and Pernambuco States. We recorded 36 genera and 38 species. Identification keys, descriptions, illustrations and images are presented for the sampled taxa.
