Bambusa xueana Ohrnb.

Bambusa basisolida W. T. Lin (J. Bamboo Res. 16(3): 23. 1997) was described from sterile material from Guangdong (Yangchun). In the protologue it was compared with B. subtruncata.

Bambusa concava W. T. Lin (J. Bamboo Res. 16(3): 24. 1997) was described from sterile material from Hainan (Haikou). In the protologue it was compared with B. duriuscula.

Bambusa multiplex (Loureiro) Raeuschel ex Schultes & J. H. Schultes var. lutea T. H. Wen (J. Bamboo Res. 1(1): 31. 1982) was described from Zhejiang. The holotype (X. Q. Hua et al. 81901, ZJFI) has an abaxially pale green leaf blade, glabrous culm internodes, subfalcate culm sheath auricles, and abaxially glabrous culm sheath blades. Because these characters are so different from those of B. multiplex, it is not reasonable to recognize it as a variety of that species. According to field records, its culms are up to 3 m high and 1–2 cm in diam. As the holotype is fragmentary and very difficult to identify, further investigations are required to place this taxon effectively.
