灌木或小乔木，高4-10米，稀更高；幼枝黄绿色，无毛；老枝棕褐色，具纵棱条。叶薄革质，倒卵形或卵状椭圆形，长5-12 (15) 厘米，宽3-6厘米，先端锐尖，基部楔形，边缘上部具不明显圆齿状小锯齿，呈波状或近全缘，上面深绿色，下面淡绿色；中脉下陷，下面明显突起，侧脉4-5对，弧状上弯，在近缘处相连接，两面无毛；叶柄长1-2厘米，无毛，上面有浅槽沟。腋生总状花序，通常短于叶，长3-7 (9) 厘米，单生或稀2-3束生，直立；花序轴及花梗被短柔毛；花多数，2-3个簇生，稀单生；花梗细，长约2毫米，被短毛；苞片线状钻形，长1-2毫米；萼筒浅杯状，被疏柔毛，萼片三角状披针形，长1.5毫米，被微毛；花瓣白色，披针形，长2.5-3毫米，花时直立，顶端稍内弯，无毛；雄蕊与花瓣近等长或稍长于花瓣；花丝有微毛；子房上位，被密长柔毛；柱头头状。蒴果长圆状披针形，长6-9毫米，被微毛，具纵条纹。花期3-5月，果期5-12月。
产福建、湖南、广东、广西、云南西北部及西藏东南部。常见于海拔140-2400米的山地、山谷、疏林、路边及溪边。印度东部、不丹、越南和老挝也有分布。模式标本采自香港。
本种自印度东部至我国西南部、南部及越南、老挝有广泛分布。叶形、大小及锯齿多变化。广东尤其香港的标本的叶缘常呈波状或具圆钝小齿，稀近全缘，侧脉4-5对，稀6对，而产于云南西北部（贡山）及西藏东南部（墨脱）的植物，叶较大，边缘的锯齿密而尖，侧脉可达7-9对，与本种上述地区的标本有较明显的不同。它们是 I. kiukiangensis 抑或是近缘种的误定，有待于进一步的研究。
曾被张宏达（1953）提及和引证的狭叶老鼠刺 I. chinensis Hook. et Arn. f. angustata Wu (in Engl. Bot. Jahrb. 71: 178. 1940)，但在原始文献中无任何有关此变型的记载，故暂不列入。

Shrubs or small trees, 4-10 m tall, rarely much taller. Young branchlets yellow-green, glabrous; old branchlets brown, striate. Petiole 1-2 cm, glabrous, sulcate adaxially; leaf blade abaxially pale green, adaxially deep green, obovate or ovate-elliptic, 5-12(-15) × 3-6 cm, thinly leathery, both surfaces glabrous, midvein distinctly raised abaxially, impressed adaxially, secondary veins in 4 or 5 pairs, arcuate curved upward, connected near margin, base cuneate, margin obscurely crenate-serrulate distally, repand, or subentire, apex acute. Racemes axillary, solitary or rarely 2- or 3-fascicled, erect, usually shorter than leaves, 3-6(-9) cm, glabrous; rachis puberulous; bracts linear-subulate, 1-2 mm. Flowers numerous, 2- or 3-clustered, rarely solitary; pedicel slender, ca. 2 mm, puberulous. Calyx shallowly cupular, sparsely pubescent; lobes triangular-lanceolate, ca. 1.5 mm, puberulous. Petals erect at anthesis, white, lanceolate, 2.5-3 mm, glabrous, apex emarginate. Stamens subequaling or slightly longer than petals; filaments puberulous. Ovary superior, densely villous. Stigma capitate. Capsule striate, oblong-lanceolate, 6-9 mm, puberulous. Fl. Mar-May, fr. May-Dec. 2n = 22.
Sparse forests, mountain slopes, valleys, streamsides, roadsides; 100-2400 m. Fujian, Guangdong, Guangxi, Hunan, SE Xizang, NW Yunnan [Bhutan, India, Laos, N Myanmar, Thailand, Vietnam].
This is a widespread species variable in the shape, size, and marginal dentation of the leaf blades.
