Vascular flora of Lençóis Maranhenses National Park, Maranhão State, Brazil: checklist, floristic affinities and phytophysiognomies of restingas in the municipality of Barreirinhas

A floristic survey of Lençóis Maranhenses National Park, Brazil, identified 289 vascular plant species across 73 families, with notable richness in Poaceae, Cyperaceae, Fabaceae, Rubiaceae, Eriocaulaceae, and Myrtaceae. The study recorded 56 new occurrences for the state of Maranhão and revealed low floristic similarity among restinga areas in North and Northeastern Brazil, suggesting high endemism or potential collection bias. The research combined herbarium data with field collections (2015–2017) and applied UPGMA clustering using Jaccard index to analyze affinities.
