walking stick bamboo
Vascular – Exotic
Fairly dense thicket-forming bamboo with rhizomes running extensively. The culm (stem) usually 3-6 m is green during the first year, yellow afterwards. The nodes on some shoots are congested and sometimes zigzag towards base, internodes swollen and often asymmetric. Branches spreading widely to give an open network. Leaf blade usually 5-13 x 0.7-2 cm, lanceolate and pointed.
There are other spp. of Phyllostachys in N.Z. with yellow stems but P. aurea is easily recognisable by the swollen and asymmetric internodes and zigzag nodes in the lower part of some culms in a clump. The cultivated P. edulis (Carriere) Houz. ”Heterocycla” also has lower internodes on some culms strongly swollen and grossly asymmetric, giving rise to zigzag nodes. However, the culm-sheaths are hairy abaxially in P. edulis but glabrous in P. aurea.
Flowering not reported in NZ (Edgar and Connor 2002).
