Ipomoea buriliae (Convolvulaceae), a new species of morning glory discovered in the Borborema Plateau, northeastern Brazil

Ipomoea buriliae Belo (Convolvulaceae) is described and illustrated as a new species. We provide a taxonomic treatment along with anatomical, cytogenetic, and palynological descriptions for this new species. Additionally, we include illustrations, photographs, and details about its geographical distribution and conservation status. A comparative list highlights key morphological characters of I. buriliae in relation to closely related species. It shares some morphological similarities with I. parasitica (Kunth) G.Don. However, I. buriliae is distinguished by its white corolla, spiny projections on the stem, petiole, and peduncle, as well as a campanulate corolla and tector trichomes along the filaments.
