Inventário florístico de Convolvulaceae juss. no município de Cuité - PB.

Abstract

The Convolvulaceae family is widely distributed in tropical and temperate regions of the world. In Brazil, due to the large number of species with herbaceous and scandent habit, it develops well in all phytogeographic domains. In the Caatinga, it stands out as the first group to present flowers with pink, white, and blue tones at the beginning of the rainy season and is the last to still present flowers when the rains come to an end. It is known that the volume of taxonomic studies related to Convolvulaceae produced in the semi-arid region still leaves many information gaps, particularly in the state of Paraíba. Thus, the floristic survey conducted in Cuité, in the agreste region of Paraíba, aims to identify the species occurring in the region, bringing to light data on the floristic composition of Convolvulaceae. The period of material collection comprised the months from August 2023 to August 2025, at different points in the municipality, covering the beginning to the end of the rainy season during two moments throughout this year of work. The collected material received the usual treatment for taxonomic studies of this nature, was identified and incorporated into the HCES collection. In the municipality of Cuité–PB, 19 species of Convolvulaceae were recorded, distributed in five genera, corresponding to about 23% of the family’s species in Paraíba. Ipomoea decipiens deserves to be highlighted as it represents the second record for the municipality of Cuité in this study. In general, the species cited here show a wide regional distribution, also occurring in the states of Rio Grande do Norte and Pernambuco, which reflects the floristic similarity among the surrounding regions.
