Valerians tangutica Bat. in Act. Hort. Petrop. 13: 375. 1894; Hand. -Mazz. in Act. Hort. Gothob. 9: 175. 1934; 中国高等植物图鉴4: 334, 图6081. 1925.
细弱小草本，高10-15 (-20) 厘米，全株无毛；根状茎斜升，顶端包有膜质纤维状老叶鞘；根细带状，根状茎及根均具有浓香味。基生叶薄纸质，心状宽卵形或长方状卵形，长1-2-4厘米，宽约1厘米，全缘或大头羽裂，顶裂片圆或椭圆形，长宽约1厘米，全缘，侧裂片1-2对，小椭圆形或狭椭圆形，两端均钝圆，全缘；叶柄长达5厘米；茎上部叶羽状3-7深裂，裂片线状披针形，全缘。半球形的聚伞花序顶生，直径1-2厘米；小苞片披针形，边缘膜质。花白色或有时粉红色，花冠筒状漏斗形，长5-6毫米，花冠5裂，裂片倒卵形；雌雄蕊近等长，均伸出于花冠之外。子房椭圆形、光秃。花期6-7月，果期7-8月。
产内蒙古、宁夏、甘肃、青海。生于山沟或潮湿草地，海拔1200-3600米。模式标本采自甘肃西南部。
产于贺兰山的某些标本（何业祺2476、2862），具有较短的雌雄蕊和短而宽的子房，略似 V. daghestanica Rupr., 但因标本量少，且标本不够成熟，暂记于此，待日后查改。

小缬草 xiao xie cao
Plants 10-20 cm tall, glabrous throughout. Rhizomes ascending, 0.5-2 cm, usually covered with fibrous remains of old leaves; roots fibrous, ca. 0.5 mm in diam. Stems erect, simple. Basal and lower cauline leaves long petiolate; petiole to 5 cm; blade broadly ovate to oblong-ovate, 1-4 × 1-1.5 cm, margin entire. Middle cauline leaves lyrate; terminal lobe orbicular or oblong, ca. 1 × 1 cm; lateral lobes 1- or 2-paired, reduced, elliptic to linear-elliptic, margin entire, apex obtuse. Upper cauline leaves pinnatifid; segments 5-7, linear-lanceolate, entire; terminal one larger. Inflorescence semiglobose, 1-2 cm in diam.; bracts and bracteoles lanceolate, membranous. Corolla white, rose, pink, or sometimes purplish, funnelform, 5-6 mm; lobes obovate, nearly as long as tube. Stamens and style exserted. Achenes ovoid-ellipsoid, ca. 3 × 1 mm, glabrous. Fl. Jun-Jul, fr. Jul-Aug.
● Meadows, forests; 2000-3900(-4200) m. Gansu (Jiayuguan, Lintan, Sunan), SW Nei Mongol (Alxa Zuoqi), NW Ningxia (Helan Shan), N and NE Qinghai, Sichuan (Xiangcheng).
