The Chinese record of Cyrtosperma lasioides Griffith (Fl. Hainan. 4: 129. 1977; FRPS 13(2): 13. 1979) was based on W. T. Tsang 553, collected in Hainan. This was, however, a misidentification, and the plants are actually Lasia spinosa (see H. Li et al., Acta Phytotax. Sin. 41: 577-581. 2003).
The young leaves are used as a vegetable. The rhizomes are used medicinally for treating tuberculosis of lymph nodes, swollen lymph nodes, stomach aches, snake and insect bites, injuries, and rheumatism.
