Impatiens oxyanthera Hook. f. in Nouv. Arch. Mus. Nat. Hist. Paris. ser. 4, 10: 254. 1908.
一年生草本，高20-40厘米，全株无毛。茎直立，细，不分枝。叶互生，具短柄，或上部的叶近无柄；叶片膜质，卵形或卵状披针形，长6-8厘米，宽3.5-4厘米，顶端急尖或渐尖，基部楔形，狭成长1.5-3厘米的叶柄，边缘具粗锯齿，齿端具小尖，侧脉4-5对；上面深绿色，下面浅绿色，基部无腺体或具少数缘毛状腺体。总花梗生于上部叶腋，长于叶柄，而短于叶，纤细，具2花；花梗长10-15毫米，下面的在基部，上面的在中部具苞片；苞片卵形，长2-5毫米，顶端突尖。花大，红色或淡紫红色，长2-2.5厘米；侧生萼片2，圆形或椭圆形长5-6毫米，宽3-4毫米，顶端具长尖头，具5条脉；旗瓣圆形，直径15毫米，中肋背面增厚，具龙骨状突起，顶端具弯曲突尖；翼瓣无柄，长20-25毫米，2裂，基部裂片圆形，较上部边缘突尖，上部裂片较长，狭斧形或马刀形，弯曲，顶端钝，背部具圆小耳；唇瓣檐部近囊状漏斗形，长2.5厘米，口部斜升，宽15毫米，先端尖，基部狭成短于檐部内弯的钝距，具红色条纹。花丝短，钻形；花药卵圆形，顶端尖。子房纺锤状，直立，具5条肋，急尖。蒴果线形，长1.5厘米。花期9月。
产四川（峨眉山、洪雅、峨边、南川）。生山坡林缘或路旁阴湿处，海拔1900-2200米。模式标本采自四川峨眉山。
此种茎下部或基部常肿大成块状，具多数须根与块节凤仙花 I. pinfanensis Hook. f.近似，但后者总花梗仅具1花，向上部具苞片；花较大，粉红色，旗瓣背面中肋顶端以下具明显的喙，与本种有别。

Plants annual, 20-40 cm tall, glabrous. Stem erect, simple. Leaves alternate, shortly petiolate or upper leaves subsessile; petiole 1.5-3 cm; leaf blade pale green abaxially, dark green adaxially, ovate or ovate-lanceolate, 6-8 × 3.5-4 cm, membranous, without glands or with few ciliate glands at base, lateral veins 4 or 5 pairs, base cuneate, attenuate into petiole, margin coarsely serrate, teeth mucronulate, apex acute or acuminate. Inflorescences in upper leaf axils, 2- or 3-flowered; peduncles longer than petioles, slender. Pedicels 1-1.5 cm, bracteate at base (but appearing as if at middle in upper flowers); bracts ovate, 2-5 mm, apex cuspidate. Flowers red or purplish red, large, 2-2.5 cm.

Lower sepal subsaccate-funnelform, ca. 2.5 cm deep, narrowed into an incurved spur; spur red striate, shorter than limb; mouth oblique, ca. 1.5 cm wide, tip acute. Upper petal orbicular, ca. 1.5 cm in diam., apex curved, long mucronulate, abaxial midvein thickened, carinate; lateral united petals not clawed, 2-2.5 cm, 2-lobed; basal lobes orbicular; distal lobes curved, narrowly dolabriform or falcate, longer, apex obtuse (or ?mucronate); auricle inflexed, narrow.
