Phyllostachys atrovaginata C. S. Chao et H.Y. Chou in Act.Phytotax. Sin.18(2): 191.f. 13. 1980.——P. congesta auct.non Rendle: McClure in Agr. Handb. No. 114: 27. ff. 16, 17. 1957.
竿高7-8米，径粗3-5厘米，具较短而斜上伸展的分枝，致使外形窄狭，呈塔形，幼竿绿色，微被白粉，无毛；竿中部节间长29-31厘米，壁厚3-5毫米；竿环与箨环均中等隆起。箨鞘背面墨绿色，下部有时带紫红色，箨边带黄褐色，有多条紫黑色纵脉纹，若生于竹林内部的竿箨，则箨鞘可变为深绿色，其上脉纹为紫色，无斑点，无毛或稀可微被疏毛；箨耳及鞘口繸毛俱缺，或偶有疏生的鞘口繸毛；箨舌宽而低，两侧不露出，绿褐色，截形，边缘近于无纤毛或有极短的纤毛；箨片三角形至三角状披针形，直立，波状至微皱曲，墨绿色，边缘紫红色。末级小枝具2或3叶；叶耳及鞘口繸毛均不明显；叶舌背面密被细毛，有时基部生长粗毛；叶片带状披针形，长5.5-13厘米，宽0.9-1.6厘米。笋期4月底至5月初。
产浙江，栽培不普遍。模式标本采自杭州古荡。
竹材篾性好，为较好的材用竹种；笋可食，但笋味略差。
McClure曾将由我国浙江塘栖引入美国栽培的一种竹种误认为是P.congesta Rendle, 但根据他的描述和图来看，实应是本种。

Culms 7–8 m, 3–5 cm in diam.; internodes green, 29–31 cm, initially inconspicuously white powdery, glabrous; wall 3–5 mm thick; nodes with both ridge and sheath scar moderately prominent. Culm sheaths dark green, with purple-black stripes and pale yellow-brown margins, base sometimes purple-red, or deep green with purple veins in shade, unmarked, glabrous or rarely sparsely strigose; auricles absent; oral setae absent or occasionally sparse; ligule green-brown, truncate, short, broad, completely covered by base of blade, subglabrous or minutely ciliolate; blade erect, dark green, with purple-red margins, triangular to triangular-lanceolate, wavy to weakly crinkled. Leaves 2 or 3 per ultimate branch; auricles and oral setae inconspicuous; ligule short, scarcely exserted, densely puberulent, sometimes hirsute at base; blade 5.5–13 × 0.9–1.6 cm. Inflorescence not known. New shoots late Apr to early May.
* Cultivated. Jiangsu, Zhejiang.
The shoots are edible, and the culms are used split or unsplit for weaving bamboo articles.
