Vellozia inselbergae Mello-Silva ex Andr.Cabral, a new species of Velloziaceae endemic to the Atlantic Forest inselbergs in the Brazilian state of Bahia, is here described. The new species is morphologically similar to Vellozia armata and Vellozia luteola, putatively belonging to the same clade, but is distinguished from them mainly by the longer pedicel, cylindrical-ellipsoid hypanthium, white and larger tepals, stamen number, longer anthers and style, and larger capsules. Detailed morphological and anatomical descriptions, illustration and photographic plates, distribution map, and conservation status of Vellozia inselbergae are provided.
