丛生灌木，高1-1.5米，茎圆柱形，有节，直径约1厘米。叶掌状深裂成2-4裂片，裂片长圆状披针形，长15-18厘米，宽1.7-3.5厘米，具3-4条肋脉，先端通常渐狭，有不规则的急尖的齿，边缘及肋脉上具粗糙的细锯齿；横小脉不多，明显波状；叶柄很纤细，长8-11厘米，宽1.5-2毫米，上面扁平，背面稍圆，截面呈半圆形，边缘具脱落性的鳞秕状物顶端具钝三角形或几圆形的小戟突；叶鞘被褐色、网状的细纤维。花序长约20厘米，分枝少，极张开；花序梗上有2-3个大佛焰苞，管状，长4-7厘米，顶端一侧裂开；花小，雌雄异株。果实球形，蓝绿色，直径8-9毫米；果被高5毫米，花萼几乎裂至一半，裂片形；花冠裂片变成长而纤细的实心柱状体，长3-4毫米。种子1颗，球形，直径6-米。果期10月。
产广东西部，海南及广西南部。模式标本采自广东云浮。
树形矮小优美，可作庭园绿化材料。

细棕竹 xi zong zhu
Stems clustered, rhizomatous, forming colonies, to 2 m tall, to 0.5 cm in diam., covered with persistent, fibrous leaf sheaths. Leaf sheaths with fine, black or brown fibers producing a square mesh; ligules persistent; blades split to base, divided into 2-4 segments, these with curved sides and ± pointed apices, to 20 × 3.5 cm. Inflorescences borne among leaves, branched to 2 orders; bracts tubular, sheathing; rachis to 20 cm; rachillae 2-3 cm, ± glabrous; male flowers to 4 mm; sepals united into a tubular, 3-lobed calyx; petals united into a tubular corolla with a 3-lobed, valvate apex; stamens 6, borne in 2 series; filaments not keeled adaxially; female flowers similar to but shorter than male. Fruits developing from 1 carpel, blue-green, globose, to 0.8 cm in diam., borne on a short stalk.
Lowland forests on limestone slopes; below 900 m. Guangdong, Guangxi, Hainan [Vietnam].
