Louisiella is a genus of African, Neotropical and tropical plants in the grass family. Earlier the genus was known to comprise only two species i.e. L. fluitans and L. elephantipes. Mr. Shahid Nawaz, an agrostologist at the Blatter Herbarium (BLAT), transferred a species Panicum paludosum Roxb. into Louisiella based on critical study of the morphological features. Now, there are three globally accepted species in the genus.
