The name "Panicum nodosum var. micranthum Balansa" (J. Bot. (Morot) 4: 142. 1890) is a nomen nudum and was therefore not validly published. The combination Ottochloa nodosa var. micrantha was not previously validly published by P. C. Keng (Iconogr. Cormophyt. Sin. 5: 160. 1976) because no reference to the basionym was provided.
