Comments
The number of different generic, species, and subspecific names that have been applied to this species is indicative of complex taxonomic issues. Until greater clarity is attained, we are opting to follow the approach of Snow, the foremost expert in this group, rather than Flora of the Southeastern U.S. and Flora of Virginia. See the following:
Snow, N., P.M. Peterson, K. Romaschenko, and B.K. Simon. 2018. Monograph of Diplachne (Poaceae, Chloridoideae, Cynodonteae). PhytoKeys 93: 1-102.
