中文摘要：
应用扫描电子显微镜技术首次研究了6种风仙花属（Impatiens L．）植物的叶表皮微形态学特征，结果表明：6种风仙花属植物叶片上表皮纹饰为网状、不规则细波状或曲叉状，其中曲叉状纹饰为一种较特殊的纹饰特征；气孔仅分布在叶片的下表面，呈不规则排列，形状为椭圆形或宽椭圆形，长度在10．5—25．6μm之间，气孔外拱盖内缘平滑或近平滑，多数种类气孔的保卫细胞两极具“T”型加厚．叶表面纹饰，气孔的形状、大小及气孔保卫细胞两极“T”，型加厚等特征在种间具有一定的差异，可作为该属植物分类的重要特征之一，文中还探讨了叶表皮微形态学特征在风仙花属分类中的意义及有关紫花黄金风的分类学地位问题．
英文摘要：
Micromorphological characters of leaf epidermis of six species in the genus Impatiens （Balsaminaceae）, were examined by scanning electron microscopes （SEM） for the first time. It is found that the ornamemtation of upper leaf epidermis of six species in Impatiens is reticulate, irregular crispulate or＇ forficately wavy, forficately wavy ornamemtation is more particular; the stomata which only distribute on the lower epidermis, arrange regularly, range from 10.5 μm to 25.6μm in lenghth, elipsoid or wide ellipsoid in shape, smooth or subsmooth in inner margin of outer stoma- tal ledge, have T- thickening at the polar region of guard cells in most species. The characters in Impatiens, such as shape and lenghth of stomata, T- thickening at the polar region of guard cells and omamemtation of leaf epidermis are more important between species and can be used one of the taxonomically important characters of Impatiens. In addition, taxonomical value of micromorphological characters of leaf epidermis in Impatiens and taxonomical status of Impatiens sic- ulifer var. porphyrea were discussed.
