Impatiens platychlaena Hook. f. in Nouv. Arch. Mus. Nat. Hist. Paris. ser 4, 10: 270. 1908.
一年生草本，高 (30) 60-100厘米，具少数支柱根。全株无毛，茎直立，粗壮，绿色或有时带紫色，分枝。叶互生，具柄，叶片近膜质，卵状长圆形，卵形或卵状披针形，长6-15厘米，宽3-4.5厘米，顶端渐尖或尾状渐尖，基部楔状狭成长2-5厘米的叶柄；或上部的叶近无柄，基部圆形或心形，边缘具粗圆齿状锯齿，齿端凹且具小尖，齿间无刚毛，上面绿色，下面淡绿或有时紫色，侧脉7-8 (9) 对，两面无毛。总花梗着生于茎枝顶端，长0.5-2厘米，纤细，具1-2，稀3花；花梗短，长5-10毫米，中部或中上部具苞片；苞片卵形或卵状披针形，长3-4毫米，宽约2毫米，渐尖，宿存。花大，长3-4厘米，通常两色。侧生萼片2，宽圆形，膜质，宽13-15毫米，在干时泥褐色至紫红色，全部或具紫色斑点，有光泽，背面中肋不增厚，具多数脉。旗瓣圆形，宽达15毫米，紫色或黄色，顶端2浅裂，在凹入处具小尖，背面中肋增厚，具宽鸡冠状突起，有色，全缘或2裂；翼瓣无柄，长2.5-3厘米，2裂，基部裂片圆形，顶端具细丝，上部裂片略长，长斧形，具细丝，背部具伸长而反折的小耳；唇瓣深囊状，长2.5-3厘米，基部圆形，急狭成粗而内弯2裂的短距，口部近平展或稍斜上，先端急尖。花丝短宽；花药钝。子房纺锤状，直立，渐尖。蒴果线形，长2.5-4厘米，顶端急尖。种子多数，长圆形，长2-3毫米。花期8-9月，果期10月。
产四川（峨眉山）。生于林缘或灌木丛中潮湿处或路边林下，海拔750-2500米。模式标本采自峨眉山。
此种花大，常生于茎枝端而藏于上部叶中，侧生萼片和旗瓣紫红色或具紫红色斑点；旗瓣中肋背面明显增厚具宽鸡冠状突起；冀瓣的裂片顶端具细丝，唇瓣深囊状，具粉红色条纹，似与短柄凤仙花 I. brevipes Hook. f. 近缘。

Plants annual, (30-)60-100 cm tall, glabrous, with few supporting roots. Stem erect, green or sometimes purple-tinged, robust, branched. Leaves alternate; petiole 2-5 cm, upper leaves subsessile; leaf blade pale green or sometimes purple abaxially, green adaxially, ovate-oblong, ovate, or ovate-lanceolate, 6-15 × 3-4.5 cm, submembranous, glabrous, lateral veins 7 or 8(or 9) pairs, base cuneate, narrowed, or cordate, margin coarsely crenate-serrate, teeth retuse, mucronulate, apex acuminate or caudate-acuminate. Inflorescences terminal at apices of branches, 1- or 2(or 3)-flowered; peduncles 0.5-2 cm, slender. Pedicels short, 0.5-1 cm, bracteate above middle; bracts persistent, ovate or ovate-lanceolate, 3-4 × ca. 2 mm, apex acuminate. Flowers usually bicolored, large, 3-4 cm deep. Lateral sepals 2, brown to purple-red when dry, purple spotted, orbicular, 1.3-1.5 cm wide, shiny, many veined, abaxial midvein not thickened. Lower sepal deeply saccate, 2.5-3 cm deep, abruptly narrowed into an incurved spur; spur stout, short, 2-lobed; mouth subvertical or slightly ascending, tip acute. Upper petal purple or yellow, orbicular, ca. 1.5 cm, apex retuse, mucronulate, abaxial midvein thickened, broadly cristate; lateral united petals not clawed, 2.5-3 cm, 2-lobed; basal lobes orbicular, apex with a filamentous long hair; distal lobes dolabriform, longer, with a long filamentous hair; auricle inflexed, narrow. Filaments short, broad; anthers obtuse. Ovary erect, fusiform. Capsule linear, 2.5-4 cm. Seeds many, oblong, 2-3 mm. Fl. Aug-Sep, fr. Oct.
● Forest margins, thickets, moist places, roadsides; 700-2500 m. Sichuan (Emei Shan).
