Impatiens hunanensis Y. L. Chen, in Acta Phytotax. Sin. 27(5): 402. fig. 4. 1989.
一年生草本，高30-60厘米，茎肉质，直立，不分枝或分枝，干时有条纹，下部节膨大，具多数纤维状根，上部被疏短柔毛。叶近膜质，互生，具柄，卵形或卵状披针形，长5-13厘米，宽2.5-5厘米，顶端渐尖或短尾尖，边缘具粗圆齿或圆齿状锯齿，齿间具细刚毛，基部狭成长2.5-4厘米的细柄，中脉背面明显，被疏微毛，侧脉5-6对，弧状弯，上面绿色，被疏贴生短糙毛，下面淡绿色，沿脉有短毛。总花梗单生于上部叶腋，明显短于叶，劲直；3-4花，排成疏总状；花梗细，长5-10毫米，果期几不伸长，基部具苞片；苞片三角状卵形，长2-3毫米，凹，肉质，稍钝，宿存。花黄色，径2.5-3厘米；侧生萼片2，斜卵形或近圆形，较厚而不透明，径约5毫米，顶端以下具小尖头，具明显5-6细脉。旗瓣圆形，径10-12毫米，顶端凹，背面中肋具鸡冠状突起，冠突三角形，急尖，顶端具小尖；翼瓣长25毫米，具短柄，基部裂片圆形，上部裂片较大，稍长，斧形，顶端圆形，背部具半卵形，反折的小耳；唇瓣囊状，长达3厘米，基部急狭成长10-12毫米，钩状或内卷的距，口部斜上，长15毫米，先端急尖。花丝线形，上部扁平；花药尖，药隔分裂。子房纺锤状，略呈镰刀形，长3-4毫米，尖。蒴果（未成熟）长2.5厘米，棒状，顶端尖；种子多数。
产湖南、江西（全南、九连山）、广东（连山、连县、连南、新丰）。生于山谷林下河边或岩石上，海拔700-800米。模式标本采自江西九连山。
本种外形酷似云南产的滇南凤仙花 I. duclouxii Hook. f., 但以叶近膜质，较小，具5-6对侧脉；花2-4；萼片斜卵形，近顶端具小尖头，有5-6条明显细脉；翼瓣背部具半卵形反折的小耳与后者相区别。前人曾将采自湖南武岗云山的植物误列于滇南风仙花，显然是不适宜的。虽然我们未看到所引证的标本，但从上述的标本与该种的原始记载相比较，无论在叶的质地，或是侧脉的数目和花的各部形态都有所不同。因此Handel-Msuetti 采自湖南的植物无疑应为本种。

湖南凤仙花 hu nan feng xian hua
Plants annual, 30-60 cm tall. Stem erect, striate when dry, succulent, simple or branched, lower nodes turgid, with many fibrous roots, sparsely pilose in upper part. Leaves alternate; petiole 2.5-4 cm, slender; leaf blade greenish abaxially, green adaxially, ovate or ovate-lanceolate, 5-13 × 2.5-5 cm, membranous, abaxially pilose on veins, adaxially sparsely adpressed strigose, setose between teeth, midvein prominent, sparsely puberulent, lateral veins 5 or 6 pairs, curved, base attenuate into petiole, margin coarsely crenate or crenate-serrate, apex acuminate or shortly caudate. Inflorescences in upper leaf axils, racemose, laxly 3- or 4-flowered; peduncles conspicuously shorter than leaves, strict. Pedicels 5-10 mm, slender, bracteate at base; bracts persistent, triangular-ovate, 2-3 mm, fleshy, retuse, slightly obtuse. Flowers yellow, 2.5-3 cm in diam. Lateral sepals 2, obliquely ovate or suborbicular, thick, ca. 5 mm in diam., conspicuously 5- or 6-veined, apex mucronulate. Lower sepal saccate, ca. 3 cm deep, abruptly narrowed into a hooked or incurved spur 1-1.2 cm; mouth oblique, ca. 1.5 cm, tip acute. Upper petal orbicular, 1-1.2 cm in diam., apex retuse, mucronulate, abaxial midvein cristate, crista triangular, apically acute; lateral united petals ca. 2.5 mm, shortly stipitate; basal lobes orbicular; distal lobes dolabriform, larger, apex rounded; auricle inflexed, subovate. Filaments linear; anthers acute. Ovary fusiform, slightly curved, 3-4 mm. Capsule (immature) ca. 2.5 cm, clavate. Seeds many. Fl. Jun, fr. Jun-unknown.
