Detailed description
Fairly dense thicket-forming bamboo with rhizomes running extensively. Culm (stem) usually 3–6 m, green during the first year, yellow afterwards. 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 × 0.7–2 cm, lanceolate and pointed.
Similar taxa
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. heterocycla (Carrière) S.Matsum. 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. heterocycla but glabrous in P. aurea.
