5. AMPELOCALAMUS
Clump-forming thornless pendulous to scrambling bamboos, up to 12m tall, with long culm internodes of up to more than 40cm, no cross-veins on the leaves, short broad buds and long pendulous culm tips. This genus is quite similar in appearance to the other medium stature subtropical clump-forming pendulous genera, Cephalostachyum and Teinostachyum, although their branches and inflorescences show that they are not closely related. Culm nodes may be substantially thickened or modified into a flange
