[fieldguides.fieldmuseum.org] [1363] version 1 9/2021 Palm swamps are typical environment of the Cerrado domain. However, they also occur in ecological refugia, in isolated stretches of drainage headwaters in the Araripe sedimentar basin, in the South of Ceará state. These lie inside the drought polygon of the northeastern Brazil, where the xerophytic Caatinga vegetation predominates. These refugia betray a complex paleoclimatic and paleoecological evolution, being maintained by local particularities, and favored by the perennial water supply from seepage zones fed by the suspended aquifer of Araripe Plateau. This context allows the coexistence and coevolution of the palm swamp within an area of climatic semiaridity. This guide provides information regarding the recognition and identification of typical species of palm swamp, which were cataloged in a refugium area, locally called the Buriti Valley, in the township of Santana do Cariri, state of Ceará. 1 Mendoncia sp. 2 Ruellia inundata 3 Blepharodon pictum 4 Acrocomia intumescens 5 Attalea speciosa ACANTHACEAE ACANTHACEAE APOCYNACEAE ARECACEAE ARECACEAE Santana do Cariri, Ceará, Brazil 2 Plants of Palm Swamps in the South of Ceará Maria Daniely Freire Guerra1, Priscila Orlandini2, Rayane de Tasso Moreira Ribeiro3, Maria Iracema Bezerra de Loiola4 & Rubens Teixeira de Queiroz5 1Universidade Regional do Cariri, 2Universidade Estadual de Campinas, 3Universidade Federal Rural de Pernambuco, 4 5 Universidade Federal do Ceará & Universidade Federal da Paraíba Photos by R.T. de Queiroz, M.I.B.
