Description:  "Culms 5-6 m, ca. 2 cm in diameter; internodes initially purple-green, becoming green or gray-green, to 25 cm, white powdery, glabrous or basal internodes slightly scabrous with minute, erect hairs on distal parts; wall ca. 4 mm thick; nodal ridge slightly more prominent than sheath scar. Culm sheaths deep to pale green, weakly tinged with purple, unmarked or more usually with distal milky-white stripes and extremely minute brown spots, white powdery, those from basal nodes sometimes pubescent; auricles usually present, green or purple-green, small or large and falcate; oral setae sometimes absent; ligule purple, arcuate or truncate, 1-2 mm, ciliate; blade erect, deep green or tinged with purple, narrowly triangular to triangular-lanceolate, flat or wavy. Leaves usually 2 per ultimate branch; auricles and oral setae usually present initially, deciduous; ligule moderately exserted; blade 7-11 x 1.2-1.6 cm. Inflorescence not known"  (Flora of China online).

Description from GrassBase.

Habitat/ecology:  "Woodland, Sunny Edge, Dappled Shade, Shady Edge. The plant prefers light (sandy), medium (loamy) and heavy (clay) soils. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It requires moist soil. The plant can tolerates strong winds but not maritime exposure" (Plants for a Future).

Propagation:  Rhizomes, discarded cuttings.

Native range:  China (Zhejaing and Sichuan Provinces) (Dajun & Shao-Jin, 1987; p. 63).

Comments:  A very aggressive running bamboo that has already spread widely on Mangaia, Cook Islands (Space & Flynn, 2002; p. 8).

Control: 

Chemical: Probably similar to control for P. nigra: "Plant is sensitive to hexazinone and imazapyr and moderately sensitive to glyphosate. Foliar application difficult on tall plants. Most effective treatment requires mechanical clearing followed by herbicide treatment of re-sprouts. J. De Frank (Univ. Hawaii) recommended glyphosate plus fluazifop or imazapyr. Basal stem application of imazapyr looks promising" (Motooka et al., 2002).
