Abstract Droseraceae is a family of carnivorous plants with a cosmopolitan distribution, including the genus Drosera, which is present across all continents except Antarctica. In Brazil, Drosera comprises 32 species, 20 of which are endemic. This study focuses on the taxonomic treatment of Drosera species in the state of Ceará, where Drosera sessilifolia is the only recorded species. The research includes morphological descriptions, distribution across vegetation types, phenological data, conservation notes, and threats. D. sessilifolia predominantly occurs in the Coastal Vegetation Complex ecotone, thriving in sandy soils near bodies of water and wetlands. Although widely distributed across South America and classified as Least Concern (LC), the species faces threats from habitat loss, urbanization, and pollution. The study aims to enhance understanding of the species’ distribution and highlights the need for conservation efforts to protect this unique coastal flora of Ceará, which includes floristic elements from the Caatinga, Cerrado, and coastal vegetation.
