多年生草本，高30-70厘米，根茎短粗，直生或斜生，具束生细长纺锤形块根，上部围以残存基生托叶。茎直立，2-3簇生，具棱槽，假二叉状分枝，被倒生糙毛或下部近无毛，节部稍膨大。叶基生和茎上对生；托叶三角状卵形，长4-6毫米，宽约2毫米；基生叶和茎下部叶具长柄，柄长为叶片的2-3倍，被倒向短伏毛，近叶片处被毛密集；叶片肾圆形，长4-6厘米，宽6-10厘米，掌状5深裂近基部，裂片狭菱形或楔状倒卵形，下部全缘，上部羽状浅裂至深裂，小裂片卵形或大齿状，表面被疏伏毛，背面主要沿脉被糙毛，最上部的叶近无柄，3裂，裂片狭小。花序腋生和顶生，长于叶，总花梗被倒向短糙毛，每梗具2花；苞片钻状，长2-3毫米；花梗与总花梗相似，长6-8毫米，宽约3毫米，先端具短尖头，外被短伏毛；萼片椭圆状卵形，长6-9毫米，被疏柔毛；花瓣紫红色或苍白色，倒卵形，具深紫色脉纹，长为萼片的1.5倍，先端圆形，基部楔形，具簇生白色糙毛；雄蕊与萼片近等长，花丝棕色，下部扩展，具长缘毛；雌蕊被短伏毛，花柱棕色，分枝长达5毫米。蒴果长约2.5厘米，被短糙毛。花期7-8月，果期8-9月。
分布于东北松辽平原以东的阔叶林和针阔混交林区。生于草旬、灌丛或田边杂草丛。俄罗斯远东、朝鲜和日本有分布。
Yen in Edinb. Journ. Bot. 49 (2): 134. 1992中，记载湖北宜昌，巴东和房县有本种分布。著者亲自考察过该地区，未见有本种或类似种的分布，也未见国内各标本馆存有本种的标本，故本种在湖北的分布是可疑的。

Geranium krameri Franchet & Savatier
突节老鹳草 tu jie lao guan cao
Geranium sieboldii Maximowicz.
Perennials. Rootstock ± vertical, 5-12 mm in diam., not tuberculate, with a fascicle of long thickened roots. Stem (25-)50-129 cm tall, erect, not rooting at nodes, with 0.4-0.8 mm retrorse appressed or patent nonglandular trichomes. Stipules lanceolate, distinct or connate at least at base. Leaves opposite; petiole with 0.3-0.8 mm retrorse appressed or patent nonglandular trichomes; leaf blade 5.6-11.9 cm, palmately cleft, ratio of main sinus/middle segment length = (0.81-)0.83-0.87, pilose with appressed nonglandular trichomes; segments 5 or 7, rhombic, 4.3-8.8 mm wide at base, 5-14-lobed in distal half, ratio of second sinus/middle segment length = 0.18-0.32. Cymules solitary, 2-flowered; peduncle 1.2-8.8 cm. Pedicel 2.3-5.5 cm, with 0.1-0.7 mm retrorse appressed or patent nonglandular trichomes; bracteoles lanceolate. Sepals (6.2-)7-10 mm, mucro 0.6-1.3 mm, ratio of mucro/sepal length = 0.1-0.15, outside with 0.3-0.7 mm antrorse ± appressed nonglandular trichomes, inside glabrous. Petals light pink, (1-)1.1-1.4(-1.5) cm, erect to patent, outside basally with trichomes, inside basal 1/3-1/2 with trichomes, margin basally ciliate, apex rounded. Staminal filaments pinkish, lanceolate, base slightly dilated, abaxially pilose and proximal half ciliate, trichomes 0.2-0.7 mm; anthers brown, 1.6-2.1 mm. Nectaries 5, hemispheric, abaxially glabrous, apex with a tuft of trichomes. Stigma brown. Fruit 2.6-3.1 cm, erect when immature; mericarps smooth, with a basal callus, with 0.1-0.4 mm ± patent nonglandular trichomes and apically usually with 0.4-0.7 mm patent glandular trichomes; rostrum 1.6-2 cm, with a 1.6-2.6 mm narrowed apex; stigmatic remains 4.6-6.6 mm. Seeds 1.6-2.2 mm. Fl. Jul-Aug, fr. Aug-Sep. 2n = 28.
Scrub, meadows, weedy areas in farmlands; 600-1200 m. Heilongjiang, Jilin, Liaoning [Japan, Korea, Russia (Far East)].
The indumentum of this species is variable, with patent trichomes in some specimens and retrorse and appressed in others. As in Geranium dahuricum and G. soboliferum, trichomes of petals are ± dense on the base of the inside and extending upward on veins. Geranium yesoense Franchet & Savatier is a related species endemic to Japan, Sakhalin, and Kurile Islands, with nectaries glabrous, longer petals, similar leaf blade divisions, and rootstock with thickened and not fasciculate roots.
