Geranium pseudosibiricum J. Mayer, Boehm. Abh. 238. 1786; R. Knuth in Engl. Pflanzenr. 53. 4 (129): 124. 1912; Bobr. in Schischk. et Bobr. Fl. URSS 14: 29. 1949.
多年生草本，高25-40厘米，根茎短粗，木质化，具多数粗纤维状或肥厚的根，上部围以残存基生托叶。茎多数，下部仰卧，具明显棱槽，假二叉状分枝，被倒向短柔毛，上部混生腺毛。叶基生和茎上对生；托叶三角形，长4-5毫米，宽1.5-2毫米，先端长渐尖，外被短柔毛；基生叶和茎下部叶具长柄，柄长为叶片的2-3倍，被短柔毛和腺毛，向上叶柄渐短；叶片肾圆形，掌状5-7裂近基部，裂片菱形或倒卵状楔形，下部全缘，上部羽状浅裂至深裂，下部小裂片条状卵形，常具1-2齿，先端急尖，具短尖头，表面被疏伏毛。背面主要沿脉和边缘被柔毛和腺毛；总状花序腋生，总花梗具1-2花；苞片钻状披针形，长2-3毫米；花梗与总花梗相似，长为花的1.5-2倍，直生或果期花梗基部下折，花梗上部向上弯曲；萼片长卵形或椭圆状长卵形，长5-7毫米，宽3-4毫米，先端具长1-1.5毫米尖头，外被短柔毛和长腺毛；花瓣宽倒卵形，紫红色，长为萼片2倍，先端钝圆，基部楔形，被长柔毛；雄蕊稍长于萼片，花药棕色，花丝下部扩展成长卵状，仅边缘被长缘毛；雌蕊密被微柔毛，花柱暗紫红色，无毛。蒴果长约2-2.5厘米。被短柔毛和开展腺毛。花期7-8月，果期8-9月。
分布于新疆。生于海拔1 000-1 500米的山地草、河谷泛滥地、林缘等。东欧、中亚山地、哈萨克斯坦、蒙古有分布。
同一产地或同一环境中部分植株无腺毛。在《苏联植物志》（1949年）中将无腺毛者作变种处理，这种同一种群中的变异现象作变种处理可能是不恰当的，应深入研究之后再作适合处理。同时这种无腺毛的变种非常相似 G. albiflorum Ledeb. 著者野外观察时有时确实难分，有待今后进一步研究。

蓝花老鹳草 lan hua lao guan cao
Perennials. Rootstock ± horizontal, 5-8 mm in diam., not tuberculate, with thickened roots along rootstock. Stem 26- 60 cm tall, erect, not rooting at nodes, with 0.2-0.4 mm retrorse ± appressed nonglandular trichomes. Stipules lanceolate, distinct. Leaves 1(or 2) alternate but opposite at inflorescence; petiole with 0.2-0.5 mm retrorse ± appressed nonglandular trichomes; leaf blade 3.9-7.4 cm, palmately cleft, ratio of main sinus/middle segment length = (0.81-)0.87-0.91, pilose with appressed nonglandular trichomes; segments 5 or 7, rhombic, 1.7-4.5 mm wide at base, 8-22-lobed in distal half, ratio of second sinus/middle segment length = 0.18-0.29(-0.41). Cymules solitary or in aggregates at apex of each branch, 2-flowered; peduncle 1.4-5.6(-11.5) cm. Pedicel 0.8-2.1 cm, with 0.2-0.5 mm retrorse not appressed nonglandular trichomes and sometimes 0.2-0.4 mm patent glandular trichomes; bracteoles lanceolate. Sepals 3.4-5.8 mm, mucro 0.7-1.7 mm, ratio of mucro/sepal length = 0.12-0.31, outside with 0.4-1.2 mm ± patent nonglandular trichomes and sometimes 0.2-0.6 mm patent glandular trichomes, inside glabrous. Petals purplish, 1-1.1 cm, erect to patent, outside glabrous, inside basally with trichomes, margin basally ciliate, apex rounded. Staminal filaments white, lanceolate, abaxially pilose and proximal half ciliate, trichomes 0.2-0.4 mm; anthers bluish, 1.2-1.4 mm. Nectaries 5, hemispheric, glabrous. Stigma purplish. Fruit 2.3-2.5 cm, erect when immature; mericarps smooth but sometimes with 1 or 2 transversal veins at apex, with a basal callus, with 0.1-0.3 mm ± appressed nonglandular trichomes and 0.6-0.8 mm patent glandular trichomes; rostrum 1.7-1.8 cm, with a 2-3 mm narrowed apex; stigmatic remains 1.5-2.2 mm. Seeds 2.3-2.4 mm. Fl. Jul-Aug, fr. Aug-Sep. 2n = 28.
Forest margins, meadows; 1000-1500 m. Xinjiang [Kazakhstan, Mongolia; NE Europe].
Specimens of Geranium pseudosibiricum usually have glandular trichomes restricted to fruit. Gynodioecious specimens have shorter petals (5-6 mm) and anthers not well developed.
