多年生草本，高10-20厘米。根茎细长，横生，节部常念珠状膨大，膨大处生有不定根和常发育有地上茎。茎直立，细弱，被倒向短柔毛或下部近无毛，具1-2分枝。叶互生；托叶披针形，长4-5毫米，宽1.5-2毫米，基部合生；基生叶和茎下部叶具长柄，柄长为叶片的4-6倍，密被倒向短柔毛；叶片肾圆形，长2-3.5厘米，宽2.5-4厘米，掌状5-7深裂至基部，裂片倒卵形，1-2次羽状深裂，小裂片矩圆形或宽条形，先端急尖，表面被疏伏柔毛，背面仅沿脉被伏毛。花序腋生和顶生，明显长于叶，每梗具2花或为4花的二歧聚伞状；总花梗密被倒向短柔毛；苞片披针形，长5-8毫米，宽2-3毫米，边缘被长柔毛；花梗与总花梗相似，长为花的1.5-2倍，下垂；萼片披针形或披针状矩圆形，长8-10毫米，宽4-5（6）毫米，外被长柔毛；花瓣紫红色，倒卵圆形，长为萼片的2倍，先端截平，基部骤狭，背面基部被长毛；雄蕊与萼片近等长，花丝淡棕色，下部扩展，被疏柔毛，花药深紫色；子房被伏毛，花柱分枝暗紫色。蒴果长2-3厘米，被疏短柔毛。花期7-8月，果期9-10月。
分布于陕西秦岭、甘肃、青海、四川西北和西部、云南西北和西藏东部。生于海拔2 500-5 000米的山地针叶林缘草地、亚高山和高山草甸。尼泊尔也有分布。模式标本产于青海和甘肃之间的大通河中下游。
全草入药（四川），能清热解毒，主治咽喉肿痛、肺热咳嗽等病。

Geranium pylzowianum Maximowicz
甘青老鹳草 gan qing lao guan cao
Geranium orientalitibeticum R. Knuth.
Perennials. Rootstock tubercles subglobose, 3.7-6.9(-17.5) × 2.4-7 mm, with nontuberous separations 0.6-5.2 cm, 0.4-0.8 mm in diam., without thickened roots. Stem 8-29(-48) cm tall, erect, not rooting at nodes, with 0.2-0.5 mm retrorse to appressed nonglandular trichomes and usually 0.5-1.6 mm patent glandular trichomes. Stipules lanceolate to ovate, distinct. Leaves 1 alternate but opposite at inflorescence; petiole with 0.2-0.6 mm retrorse to appressed nonglandular trichomes and sometimes 0.5-1.2 mm patent glandular trichomes; leaf blade 1.5-5.1 cm, palmately cleft, ratio of main sinus/middle segment length = 0.77-0.95, pilose with appressed nonglandular trichomes; segments 5, rhombic to obtriangular, 1.2-4.3 mm wide at base, 3-8-lobed in distal half, ratio of second sinus/middle segment length = 0.26-0.46. Cymules solitary, 2-flowered; peduncle 4-10.3(-15.5) cm. Pedicel 2.7-5.9(-7) cm, with 0.2-0.6 mm retrorse to appressed nonglandular trichomes; bracteoles lanceolate. Sepals 7.1-10.9 mm, mucro 0.7-1.2 mm, ratio of mucro/sepal length = 0.08-0.15, outside with 0.5-1 mm antrorse to patent nonglandular trichomes, inside glabrous. Petals deep rose pink with a whitish base, 1.6-1.8 cm, erect to patent, outside glabrous, inside basally with trichomes, margin basally ciliate, apex rounded or rarely emarginate with a 0.2-0.3 mm notch. Staminal filaments distally pink but paler at base, lanceolate, abaxially pilose and proximal half ciliate, trichomes 0.3-0.9 mm; anthers whitish tinged with blue, 1.7-2.4 mm. Nectaries 5, hemispheric, glabrous. Stigma pink to orangish red. Fruit 2.3-2.9 cm, erect when immature; mericarps smooth, with a basal callus, with 0.3-1.1 mm erect to patent nonglandular trichomes; rostrum 1.6-2.2 cm, with a 1.6-4.5 mm narrowed apex; stigmatic remains 2.8-3.5 mm. Seeds 1.7-2.2 mm. Fl. Jul-Aug, fr. Sep-Oct. 2n = 28*.
● Coniferous forest margins, subalpine meadows, alpine meadows; 2500-5000 m. S Gansu, Ningxia, Qinghai, S Shaanxi, W Sichuan, E Xizang, N Yunnan.
Geranium orientalitibeticum has been recognized by its broad leaf blade segments, petals with a paler base, and longer stigmatic remains. These features are included in the variability of G. pylzowianum. The latter has usually 1(or 2) alternate leaves along the stem and some opposite at the inflorescence. In some specimens, cauline leaves are all opposite, and then the inflorescence is branched from the basal node monochasially. Geranium donianum and G. farreri are quite similar in appearance but with rootstock without tubers and leaves always opposite. Additionally, in G. pylzowianum there are glandular trichomes on the stem base, stipule base, or inflorescence.
The whole plant is used as a local medicine for pharyngitis and cough.
