灌木或小乔木，高1-10米；幼枝黄绿色，具纵条纹；老枝深褐色，无毛。叶薄革质，卵形或椭圆形，长5-10厘米，宽2.5-5厘米，先端急尖或短渐尖，基部钝或圆形，边缘具稍内弯的刺状锯齿，上面深绿色，有光泽，下面淡绿色，两面均无毛；侧脉4-5对，弧状上弯，中脉在上面下陷，下面明显突起，网脉明显，叶柄长5-15毫米，上面具槽沟，无毛；顶生总状花序，俯弯至下垂，长达20厘米；花序轴及花梗被短柔毛；苞片钻形，长约1毫米；花多数，常3枚簇生，花梗长2毫米，在花时平展，果期下垂；萼筒浅杯状；萼片三角状披针形，长1-1.5毫米，被微柔毛，稀近无毛；花瓣淡绿色，线状披针形，长约2.5毫米，花时直立，顶端稍内弯；雄蕊常短于花瓣；花丝长约2毫米，无毛；花药长圆形；子房半下位，无毛，心皮2枚，紧贴；花柱单生，有纵沟，柱头头状。蒴果锥状，长5-6毫米，无毛。花果期5-12月。
产云南西北部、中部至东南部，四川西南部，西藏东南部，贵州和广西。生于海拔1100-3000米的针阔叶林、杂木林下或河边、岩石处。模式标本采自云南宾川。
本种在外形上近似冬青叶鼠刺 I. ilicifolia Oliv.，有时常易被误定为后者。两者主要区别在于，本种的叶较狭，长通常超过宽的2倍，边缘有较密的刺状锯齿；而后者的叶较宽，长不超过宽的2倍，在软骨质的边缘具疏生、硬刺状的粗锯齿。

滇鼠刺 dian shu ci

Itea bodinieri H. Léveillé; I. esquirolii H. Léveillé; I. forrestii Y. C. Wu; I. mengtzeana Engler.

Shrubs or small trees, 1-10 m tall. Young branchlets yellow-green, striate; old branchlets dark brown, glabrous. Petiole 0.5-1.5 cm, sulcate adaxially, glabrous; leaf blade abaxially pale green, adaxially dark green or glossy, ovate or elliptic, 5-10 × 2.5-5 cm, thinly leathery, both surfaces glabrous, midvein distinctly raised abaxially, impressed adaxially, secondary veins in 4 or 5 pairs, arcuate, reticulate veins prominent, base obtuse or rounded, margin slightly curved spinose serrate, apex acute or shortly acuminate. Racemes terminal, nodding to pendulous, to 20 cm; rachis puberulous; bracts subulate, ca. 1 mm. Flowers numerous, often 3-clustered; pedicel spreading at anthesis, pendulous in fruit, ca. 2 mm, puberulous. Calyx shallowly cupular; lobes triangular-lanceolate, 1-1.5 mm, puberulous, rarely subglabrous. Petals erect at anthesis, slightly curved apically, pale green, linear-lanceolate, ca. 2.5 mm. Stamens usually shorter than petals; filaments ca. 2 mm, glabrous; anthers oblong. Ovary semi-inferior, glabrous. Style simple; stigma capitate. Capsule conical, 5-6 mm, glabrous. Fl. and fr. May-Dec. 2n = 22*.

* Coniferous, broad-leaved, or mixed forests, streamsides, rocks; 1100-3000 m. Guangxi, Guizhou, SW Sichuan, SE Xizang, Yunnan.

In habit, this species is similar to, and is often confused with, Itea ilicifolia. However, I. yunnanensis differs in having narrower leaf blades, usually more than 2 × as long as wide, with a more densely spinose serrate margin.
