Phyllostachys aureosulcata McClure in Journ. Wash. Acad. Sci. 35: 282. f. 3. 1945, et in Agr. Handb. USDA No.114. 18. f. 10, 11. 1957. Z. P. Wang et al. in Act. Phytotax. Sin. 18(2): 180. 1980.
形态特征：竿高达9米，粗4厘米，在较细的竿之基部有2或3节常作“之”字形折曲，幼竿被白粉及柔毛，毛脱落后手触竿表面微觉粗糙；节间长达39厘米，分枝一侧的沟槽为黄色，其他部分为绿色或黄绿色；竿环中度隆起，高于箨环。箨鞘背部紫绿色常有淡黄色纵条纹，散生褐色小斑点或无斑点，被薄白粉；箨耳淡黄带紫或紫褐色，系由箨片基部向两侧延伸而成，或与箨鞘顶端明显相连，边缘生继毛；箨舌宽，拱形或截形，紫色，边缘生细短白色纤毛；箨片三角形至三角状披针形，直立或开展，或在竿下部的箨鞘上外翻，平直或有时呈波状。末级小枝2或3叶；叶耳微小或无，继毛短；叶舌伸出；叶片长约12厘米，宽约1.4厘米，基部收缩成3—4毫米长的细柄。花枝呈穗状，长8.5厘米，基部约有4片逐渐增大的鳞片状苞片；佛焰苞4或5片，无毛或疏生短柔毛，无口十耳和鞘口继毛，缩小叶呈锥状，每片佛焰苞内生5—7枚假小穗，惟最下方的l片佛焰苞内常不生假小穗。小穗含1或2朵小花；小穗轴具毛；颖1或2片，具脊；外稃长15-19厘米，耷中、上部被柔毛；内稃稍短于外稃，上半部具柔毛；鳞被长3．5毫米，边缘生纤毛；花药长6—8毫米；柱头3，羽毛状。笋期4月中旬至5月上旬，花期5—6月。
用 途：本种因其竿下部二、三节常折曲而无多大用途，主要供观赏。
产地分布：产北京、浙江。美国在1907年从浙江余杭县塘栖引入栽培。模式标本采自美国。

Phyllostachys aureosulcata McClure
黄槽竹 huang cao zhu
Culms to 9 m, to 4 cm in diam., usually geniculate at basal 2 or 3 nodes of slender culms; internodes to 40 cm, initially white powdery, pubescent or scabridulous with tubercles left by fallen hairs; nodal ridge slightly more prominent than sheath scar. Culm sheaths purple-green, usually yellow striped, often with sparse, small, brown spots, thinly white powdery, glabrous; auricles purple-cream or purple-brown, conspicuously connected with base of blade; oral setae developed; ligule purple, arcuate or truncate, broad, ciliate; blade erect, horizontal or reflexed in lower culm, purple or tinged with same colors as those of sheath, triangular or triangular-lanceolate, flat or wavy. Leaves 2 or 3 per ultimate branch; auricles minute or absent; oral setae short; ligule exserted; blade ca. 12 × 1.4 cm. Flowering branchlets spicate, ca. 8.5 cm, scaly bracts ca. 4, gradually larger; spathes 4 or 5, glabrous or sparsely puberulous; auricles and oral setae absent, blade subulate, small. Pseudospikelets 5–7 per spathe, usually absent from lowest one. Spikelets with 1 or 2 florets. Glumes 1 or 2, keeled; rachilla puberulous; lemma 1.5–1.9 cm, distally pubescent; palea slightly shorter than lemma, distally pubescent; lodicules ca. 3.5 mm. Stigmas 3. New shoots Apr–May.
* Cultivated. Beijing, Henan, Jiangsu, Zhejiang.
This very hardy species is mainly planted as an ornamental.
