Morphological characteristics: perennial herbs, tufted, erect, 20-40 cm high. The stems are thin and unbranched, and the tender parts are usually villous or inverted villous. Later, except for the nodules, all the others were hairless or almost hairless. Without flowers at the top, slender and soft stolons often stick out and take root step by step. Leaves are stipitate, with a stipe length of 0.5-4 cm, short upward gradient, sometimes sessile, densely villous when young, and gradually sparse when old; The leaves are papery, heart-shaped or oval-shaped, 3.2-8.2 cm long and 2.6-6.8 cm wide. Usually, the leaves inserted in the middle of the stem are larger, the apex is acuminate or acute, the base is heart-shaped, and the edge has slightly sparse or dense serrations or rounded serrations. Both sides are hydrophobic, sometimes only the lower veins are extremely hydrophobic. The middle rib and lateral veins are slightly concave and convex. Flowers form a cyme, sparsely paired to form a terminal pseudoraceme; Bracts are tapered upward, stipitate to subsessile, ovate to lanceolate, less than 3.5 cm long, with serrated edges, ciliate, and pilose on both sides; Pedicel 3-9 mm long, villous, often with a pair of bracteoles in the middle, bracteoles subulate, about 65438 0 mm long. Calyx bell-shaped, long 1.3- 1.8 cm, with 15 veins, inconspicuous veins, curly or sparsely puberulent outer veins, hairless inner surface, 5 teeth, slightly lipped, 3 upper lips, slightly taller, 2 lower lips, and oval or oval triangle teeth. Corolla is light blue-purple to purple-red, 2.2-4cm long, with extremely sparse pilose outside, a row of pilose on the back, pilose upper lip, middle lobe and base of corolla tube inside, glabrous at the base of corolla tube, tubular at the upper part of corolla tube, and gradually expanding at the upper part. The crown is lip-shaped, the upper lip is erect, ovoid, the top is 2-lobed or deeply lobed, the lobes are round or nearly rectangular, and the lower lip is slender and swollen. 4 stamens, slightly stronger, not protruding from the corolla, opposite or slightly lower than the lower throat of the upper lip, opposite to the middle of the corolla tube below the lobes on both sides of the lower lip. Filaments are slightly flat, glabrous, anthers are 2-loculed, glabrous, and pass through 1 locule after maturity. Ovary 4-lobed and puberulent. Style slender, longer than stamens, slightly protruding from corolla, apex 2-lobed. Disk cup-shaped, lobes inconspicuous, finger-like swelling in front. Nutlets ovoid-oblong, pubescent, slightly triangular near the base, with a small fruit navel at the base. The flowering period is May-June, and the fruiting period is June.
Distribution: Liaoning and Jilin; Born in damp places in mosses under mixed forests or coniferous forests. Japan, Korea and the Soviet Union also have it. Type specimens were collected from Japan.
