Bromeliaceae Juss. no município de Cuité - PB.

Abstract

Bromeliaceae Juss. constitutes one of the main families of neotropical monocots, comprising 3,680 species. In Brazil, it is represented by 54 genera and 1,392 species, associated with all phytogeographical domains in the country. Of the total Bromeliaceae recorded for the Brazilian flora, 23 genera and 1,192 species are considered endemic to the country. In the Caatinga, the bromeliad species that are established are drought tolerant and grow in nutrient-poor substrates. The general objective of this work is to carry out a floristic-taxonomic survey of Bromeliaceae and an area of Caatinga, thus contributing to expanding knowledge of the flora of the family in question for the flora of Paraíba. The material was collected from August 2020 to July 2022, in more preserved areas of the municipality. The collection methodology until the incorporation of the collected material followed the usuais standards used in works of this nature and incorporated into the Herbarium collection of the Education and Health Center - HCES. Nine species belonging to three subfamilies were recorded: Bromelioideae (Bromelia laciniosa Mart. ex Schult. & Schult. f., B. karatas L., Neoglaziovia variegata (Arruda) Mez., Aechmea aquilega (Salisb.) Griseb.), Tillandsioideae (Tillandsia recurvata (L.) L., T. loliacea Mart. ex. Schult. & Schult.f., T. polystachia (L.) L., T. streptocarpa Baker) and Pitcairnioideae (Dyckia spectabilis (Mart. ex Schult. & Schult.f.) Baker). The genus with the greatest species richness was Tillandsia (4 spp.), followed by Bromelia (2 spp.). Descriptions, comments on the geographic distribution, survey and comparisons of the family's diversity in areas are presented similar ones from other municipalities in Paraíba and surrounding states and identification keys for the species.
