Veronicastrum latifolium (Hemsl.) Yamazaki, Journ. Fac. Sci. Univ. Tokyo, sect. 3, 7: 130. 1957;中国高等植物图鉴, 4: 46. 图5505. 1975.——Calorhabdos latifolia Hemsl. Journ. Linn. Soc. Bot. 26: 196. tab. 4, 1890. ——Botryopleuron latifolium Hemsl. Hook. Icon. Pl. 27: sub tab. 2670, 1900.
茎细长，弓曲，顶端着地生根，长达1米余，圆柱形，仅上部有时有狭棱，通常被黄色倒生短曲毛，少完全无毛。叶具短柄，叶片圆形至卵圆形，长3-7厘米，宽2-5厘米，长略超过宽，基部圆形，平截形或宽楔形，顶端短渐尖，通常两面疏被短硬毛，少完全无毛，边缘具三角状锯齿。花序腋生，少兼顶生于侧枝上，长1.5-4厘米；苞片和花萼裂片有睫毛；花冠淡紫色或白色，长约5毫米，裂片短，正三角形，长不及1毫米。蒴果卵状，长2-3毫米。种子卵球状，长0.3毫米，具浅网纹。花期8-9月。
产四川（西至天全）、贵州、湖南、湖北。生林中或灌丛中，有时倒挂于岩石山。
与腹水草极近，体态和花冠几乎一致，但本种叶片短而宽，顶端短渐尖而非长渐尖，多少被毛，叶缘具三角状锯齿，茎大多数被短曲毛，与腹水草（亚种）异域分布而形态上可分，与细穗腹水草几乎同域，但形态上差别虽不大而却稳定且清楚可分，看来还是两个比较自然的种。

Calorhabdos latifolia Hemsley in F. B. Forbes & Hemsley, J. Linn. Soc., Bot. 26: 196. 1890.
Stems more than 1 m, apically arching and rooting, terete, apically narrowly angular, usually with yellow, short curly hairs, rarely glabrous. Leaves alternate; petiole short; leaf blade ovate-orbicular to orbicular, 4-7 X 2-5 cm, usually sparsely hispidulous, rarely glabrous, base rounded, truncate, or broadly cuneate, margin deltoid dentate, apex short acuminate. Inflorescences axillary, rarely also terminal, 1.5-4 cm; bracts narrow, ciliate. Calyx lobes ciliate. Corolla pale purple or white, ca. 5 mm, straight, limb actinomorphic; lobes deltoid, less than 1 mm. Stamens conspicuously exserted; filaments hairy. Capsule ovoid, 2-3 mm. Seeds ovoid-globose, ca. 0.3 mm; seed coat reticulate. Fl. Aug-Sep.
* Forests, thickets, sometimes hanging from rocks; 300-500 m. Guizhou, Hubei, Hunan, C to E Sichuan.
