Mature caryopsis unknown.● Cultivated on low hills, plains, and along riversides. Fujian,Guangdong, Jiangxi, Taiwan, Zhejiang.The nomen novum Bambusa albolineata was published in thebelief that the original epithet “albostriata” was blocked by the earlierbut not validly published nomen nudum “B. albostriata Hort. ex Lavalleé”(Arbor. Segrez. 306. 1877). Nevertheless, B. albolineata is legitimatebecause of the change in rank.46. Bambusa pallida Munro, Trans. Linn. Soc.

Leaf blade linear, 9–14 × 0.8–1.2 cm, abaxially subglabrous,adaxially pubescent near base.

Mature caryopsis unknown.New shoots May–Oct.● Usually cultivated, slopes near villages. Hainan.Bambusa duriuscula is similar to B. pachinensis, but has shorterinternodes, the culm sheath with hairs only near the base and margins,the apex subtruncate, the blade nearly as long as the sheath proper, andthe leaf blade narrower and abaxially glabrous. The paratype W. T. Lin31826 should be excluded from this species.48. Bambusa pachinensis Hayata, Icon. Pl.
