摘要：Chimonobambusa farcta, a new species of temperate woody bamboos from western Guangxi, China is described and illustrated. The new species is similar to C. pubescens in the solid internodes of culms, but differs in having taller culm to 7 m with longer verrucose internodes to 23.5 cm and intranodes to 4 mm, intranode usually with a ring of 7-9 root thorns below mid-culm, abaxially brown or brown-purple verrucose-setose culm leaf sheaths with indistinct transverse veins, conspicuously developed culm leaf blades to 3.2 cm long, longer foliage leaf sheaths to 5.2 cm, larger and broader foliage leaf blades to 22 x 1.4 cm. It also somewhat resembles C. convoluta, but can be easily distinguished by having solid internodes and longer intranode 2-4 mm, very prominent nodes with supranodal ridge obviously more elevated than sheath scar, usually persistent and sometimes brownish striate culm leaf sheaths, longer culm leaf blades to 3.2 cm, and abaxially glabrous foliage leaf sheaths. Based on the morphological characteristics, this new species is assigned to C. sect. Chimonobambusa. The character description of C. pubescens are revised for its culm to 2.1 m tall, 1.1 cm in diameter and glabrous foliage leaf blades. The systematic position of C. luzhiensis is discussed, and this species is proposed as a member of C. sect. Chimonobambusa.
