???? yan sheng zi jin
Corydalis rockii Fedde; C. trigibbosa H. Chuang.
Herbs; perennial (sometimes flowering first year); 10-45 cm tall; glabrous. Rhizome short; vertical; with apical leaf rosette. Stems few to many; leafy and branched throughout; arising from below apical rosette. Rosette leaves and lower cauline leaves similar; petiole 3-10 cm; vaginate at base; blade glaucous on both surfaces; adaxially especially on veins; often with pale marks in incisions; orbicular-triangular to broadly ovate; 3-7 x 3-8 cm; ternate to usually biternate; primary leaflets petiolulate; secondary sessile; obovate to broadly ovate; base cuneate; entire to ± deeply 3-divided; segments coarsely dentate or shallowly lobed into oblong obtuse mucronate teeth; upper leaves smaller; shortly stalked and less divided; ternate or even simple; with shortly auriculate membranous vaginae. Raceme 2-5(-9)-flowered; dense to lax in flower; lax in fruit; lower bracts shortly stalked; blade once to twice ternatisect or palmatisect with broad apically dentate lobes; upper flabellate; deeply dentate; uppermost lanceolate; entire; lowermost bract sometimes compound like upper leaf. Pedicel 5-20(-40) mm in flower; 10-30(-40) mm in fruit. Sepals rounded; 1-2 x 1.5-2 mm; fimbriate-dentate. Corolla white or creamy white in shade or pale grayish purple; sometimes reddish purple in sunny positions; becoming deeper colored after fertilization. Outer petals broadly acute at apex with 1-1.5 mm wide crest tapering to both ends; just reaching apex; upper petal 18-25 mm; spur cylindric or slightly tapering; downcurved to almost straight; 8-13 mm; nectary ca. 1/2 as long as spur; lower petal usually saccate in lower 1/3 with an additional pouch close to base. Stigma square; with 6 marginal simple papillae; geminate papillae lateral (submarginal) and on basal lobes. Capsule elliptic to obovoid; 13-17 x 4-5 mm; 6-17-seeded; style 2.5-3 mm. Seeds 1.5-1.7 mm; smooth; elaiosome broad; lobed. Fl. and fr. Jun-Sep.
? Walls; roadsides; rocks; in full sun but also in shade under shrubs; 1600-3200 m. E Xizang; NW Yunnan.
