It is an annual herbaceous plant, 10-30 (-60) centimeters tall. The main root can grow up to 10 centimeters long, with a few fibrous branches. The stem is slender, erect or nearly prostrate, pale green, with numerous branches near the base. There are several basal leaves, with slender petioles, 3-6 (-14) centimeters long. The leaf blade is deeply divided into three segments, with the first segment having a longer petiole, the second segment having a short or no petiole, and 2-3 deep lobes. The small lobes are inverted ovate to inverted lanceolate, 2-5 (-10) millimeters long, rounded or obtuse at the apex, and cuneate at the base, green on the surface and pale green on the back. There are numerous stem leaves, alternate, and sparse, with long petioles on the lower leaves and short petioles on the upper leaves, similar to the basal leaves. The raceme is borne at the stem and branch tips, 2-4 centimeters long, elongating to 7 centimeters when fruiting, with 6-12 flowers arranged sparsely. The lowermost bracts are similar to the upper stem leaves or shallowly 3-lobed, while the rest are inverted ovate to lanceolate and entire. The pedicel is longer than the bracts. The sepals are scale-like with fine teeth; the petals are yellow, with the upper petal 7-9 millimeters long, boat-shaped or ovate, with a very low rooster-like projection on the back, slender, conical, and nearly equal in length to the petal. The lower petal is boat-shaped and narrowly ovate, 4-6 millimeters long, the inner petal is violin-shaped, about 5 millimeters long, with a purple-black apex, a side sac, and a linear claw, nearly equal in length to the petal. The stamen bundle is about 4 millimeters long, with extremely small anthers, and the filaments are lanceolate, with nectar glands penetrating one-third of the distance. The ovary is linear, about 2.5 millimeters long, with one row of ovules, and the style is shorter than the ovary, with a 2-lobed stigma at the top, and four long papillae. The capsule is narrowly ovoid to oblong, 7-8 (-10) millimeters long, about 2 millimeters thick, green when young, and reddish-ribbed, usually with 5-10 seeds arranged in two rows. The seeds are nearly round, about 1 millimeter in diameter, black, and glossy. The flowering and fruiting period is from July to October. Distribution area.
