Abstract

Chimonobambusa pleiacantha, a newly-identified species of the genus Chimonobambusa Makino from southeast Sichuan, China, is meticulously described and illustrated herein. It is morphologically similar to Ch. tuberculata, but differs in having 4-angled internodes, thicker wall to 4.5–8.5 mm, more reclinate and elongated root thorns to 5–8 mm long, culm internodes with three grooves and two longitudinal ridges on the branch-bearing side, persistent culm leaves, densely brown-purple setose at the bottom of culm leaf sheaths together with sheath scar, developed foliage leaf fimbriae, 6–8 on each shoulder, ca. 3–8 mm long, abaxially white pubescent foliage leaf blades. Phenologically, new shoots usually appear in September to October. In the light of these key morphological and phenological characteristics, Ch. pleiacantha was identified as a new species of the genus Ch. Makino which is different from published species of this genus.
