多年生草本。茎直立或匍匐，高15-45厘米，有分枝，节上生根。叶片膜质至草质，圆形或肾圆形，长1.5-3.5厘米，宽2-7厘米，边缘不明显7裂，裂片通常有3钝圆齿，基部心形，或弯缺处开展成锐角，两面光滑或在背面脉上被极疏的短刺毛；叶柄长3-19厘米，上部被柔毛，下部光滑或有疏毛，托叶膜质，圆形。花序梗纤细，单生于枝条上部，与叶对生，长过叶柄或等长；有时因嫩枝未延长，常有2-3个花序簇生节上，小伞形花序有多数花；花无柄或有极短的柄，密集成头状；小总苞片膜质，细小，具紫色斑点；花瓣卵形，白色至淡黄色。果实长1.2-1.8毫米，宽1.5-2.1毫米，基部心形，两侧扁压，中棱明显地隆起，幼时草绿色，成熟时紫褐色或黄褐色，有紫色斑点。花果期5-9月。
产浙江、江西、福建、广东、广西、四川、云南等省区。生长在阴湿的山谷、田野、沟边、溪旁等处；海拔350-1400米。朝鲜、日本、越南也有分布。
本种与长梗天胡荽 Hydrocatyle ramiflora Maxim. 很相似，但叶片基部弯缺处开展成锐角，绝不重迭闭合，花序梗较叶柄稍长或等长。

Hydrocotyle wilfordii Maximowicz
肾叶天胡荽 shen ye tian hu sui
Stem to 45 cm, creeping, branched, proximal parts rhizomatous, distal parts erect or decumbent. Petiole 3–10 cm, essentially glabrous but pubescent near leaf blade; leaf blade orbicular or reniform-rounded, 1.5–3.5 × 2–7 cm, both surfaces glabrous or abaxially sparsely hirsute on veins, base deep-cordate, margin very shallowly 7-lobed (some leaves parted to almost middle), lobes 3-crenate. Umbel many-flowered, solitary at nodes, sometimes 2–3 fascicled at tips of branches; peduncle longer than or equaling petiole; bracts small, membranous, with purplish stains. Petals white to pale yellow. Fruit light brown with purplish stains, subglobose, 1.2–1.8 × 1.5–2.1 mm. Fl. and fr. May–Sep.
Shady wet valleys, fields; 300–1400 m. Fujian, Guangdong, Guangxi, Jiangxi, Sichuan, Taiwan, Yunnan, Zhejiang [Japan, Korea, Vietnam].
