Stems 4--16 cm, sparsely to densely subappressed puberulent, branched. Basal leaves ca. 4; petiole 2--4 cm, appressed puberulent; blade 3-fid or 3-partite, rarely 3-lobed, pentagonal, broadly ovate, or rhombic, 0.9--1.8 × 0.8--2 cm, papery, abaxially sparsely puberulent, base subtruncate or truncate-cordate, central lobe narrowly obovate or long elliptic, 3-lobed or undivided; lateral lobes obliquely obovate or obliquely flabellate, unequally 2-lobed. Stem leaves short petiolate or sessile, palmatisect, segments linear, abaxially densely pubescent. Flowers solitary, terminal, 0.9--1.5 cm in diam. Receptacle puberulent or glabrous. Sepals 5, orbicular-ovate, 3--5 mm, abaxially densely appressed yellowish pubescent. Petals 5, obovate, 5--9 × 2--5.5 mm, nectary pit without a scale, apex rounded. Stamens numerous; anthers oblong. Aggregate fruit ovoid, 5--6 × 4--5 mm.

繁殖方法
種子繁殖:7-10月果實成熟,用育苗移栽或直播法。9月上旬進行育苗,播後覆蓋少許草皮灰及薄層稻草,澆透床土,一般1-2星期後出苗,揭去稻草。待苗高6-8厘米時,進行移植。按行株距20厘米×15厘米定植。
栽培技術
生長期管理進入生長期,需追肥1次,每畝施尿素12。追肥後澆1次透水,待水下滲後23天進行中耕鬆土,保持土壤疏鬆。生長期適當增加中耕次數,有利於改善毛茛根系生長環境,促根深扎。一般生長期要進行3次中耕,特別是乾旱時和下雨過後,進行中耕十分有效。生長期田間雜草會與毛莨爭奪養分、水分和空間等,會影響毛茛生長。要見草及時拔除。同時夏季洪澇多發,應注意防洪排澇。
病蟲防治
病害有病毒病。在高溫高濕季節偶爾少數植株發生病毒,使受害葉片黃萎,發病時可立即拔除病株。 蟲害有地老虎咬斷幼苗,可用毒餌誘殺。生長期間,有紅蜘蛛為害,可用樂果乳劑2000倍液噴殺。 [1]
