Abstract
The critical study of Panicum paludosum implied that its taxonomic position within the genus Panicum is apparently discordant for its linear hilum, spongy culms, linear spikelets, barren lower floret, and upper floret smooth. These attributes best conform the circumscription of the ditypic genus Louisiella. Thus, it has been transferred into the same and a key to distinguish all the congeners in the world is provided. The close affinities and differences of this species with a close one, Panicum repense are also briefly discussed. The illustration of the spikelet and the caryopsis are included to support its new placement in Louisiella. A detailed comparison in all the three species of Louisiella is given to facilitate the proper identification.
