The name used in FRPS (9(1): 149. 1996), Dendrocalamopsis daii, was published in the belief that D. grandis was not validly published. However, the latter name is validly published as it fulfills the requirements for a descriptio generico-specifica (Stapleton & Xia, Taxon 53: 526–528. 2004).

This species is cultivated in Guangxi for its shoots and culms.
