The nominal variety of Rudbeckia grandiflora (Asteraceae) is recognized as occurring in Louisiana. A specimen recently collected by the author, plus older herbarium specimens, document this taxon’s occurrence in Bossier, Caddo, and Webster parishes. The habitats at the collection sites are discussed briefly and a rarity rank is proposed as the first step in the recognition of this taxon new for Louisiana.
