Paratypes: GSBS 31652 (CAS, KUN), F. Kingdon Ward 54 (E).

Herbs, perennial, gray-glaucous, 2-4 cm above scree surface (6-15 cm below), glabrous; stems and petioles of radical leaves attenuate to thin underground base. Rhizome obvious, vertical, to 1 cm; storage roots fasciculate, tapering distally, 3-9 cm × 1-2 mm. Bulb prominent, 5-14 × 4-8 mm, of several pale fleshy scales. Stems 2-5, with 2 subopposite leaves. Radical leaves 2-5; petiole underground, 7-12 cm, thin; blade gray-glaucous on both surfaces, with small dark spots or streaks, broadly ovate to triangular in outline, 2-3 × 2-2.5 cm, bi- to triternate; leaflets stalked, once to almost 3 × deeply ternatisect; ultimate lobes 80-150, narrowly linear, 0.3-0.6(-1) mm wide, acute, mucronate. Cauline leaves shortly petiolate to subsessile, like radical leaves, pinnae rather long stalked. Raceme corymbose, 4-7-flowered, 1-2 cm; bracts 10-20 mm, base narrowly cuneate, deeply divided into 7-14, narrowly linear, acute lobes. Pedicel 9-20 mm, erect in flower, 10-30 mm and apically arcuate in fruit. Sepals orbicular, ca. 1.5 × 2 mm, finely and sharply dentate. Corolla pale to bright blue; inner petals darker at tip; outer petals subobtuse, sometimes shortly acuminate, crest to 1 mm wide, tapering to both ends, slightly undulate-dentate, slightly overtopping apex; upper petal 14-18 mm, spur straight, cylindric, 6-8 mm; nectary ca. 1/2 as long as spur; lower petal 8-10 mm with broad ovate slightly undulate limb, claw straight or with small gibbosity at very base; inner petals 7-8 mm. Stigma broader than long, slightly emarginate; marginal papillae: median distinct, lateral broader and diffuse; geminate papillae in basal corners; basal lobes poorly developed. Capsule sharply reflexed from suberect apically arcuate pedicel, narrowly oblong, 8-13 × ca. 2 mm, 4-9-seeded; style ca. 2.5 mm. Seeds 1.2-1.3 mm. Fl. Aug-Sep.

● Alpine scree on limestone; 3900-4600 m. SE Xizang, NW Yunnan (N Gaoligong Shan, Meili Xueshan) [?NE Myanmar].

Corydalis adrienii Prain, as described in FRPS (32: 268. 1999) is in part C. myriophylla, whereas the type of C. adrienii belongs to C. melanochora.

This new species differs from Corydalis melanochlora in the more divided leaves with much narrower pointed leaf lobes, the smaller flowers with thinner straight spur, and the longer and narrower shortly styled capsule, which is reflexed from an apically slightly arcuate pedicel.

The specific epithet refers to the very numerous ultimate lobes of the leaves, from Greek μυρίος (myrios, "countless") and φύλλον (phyllon, "leaf").
