This species is used for the manufacture of bamboo furniture, for which its mottled culms are considered superior.

In Fl. China 22, this species was treated as Indosasa shibataeoides McClure (Lingnan Univ. Sci. Bull. 9: 32. 1940 ["shibataeaoides"]); however, after publication, it was discovered that the accepted name should be I. acutiligulata.
