摘　　要：诸葛菜复合体Orychophragmus violaceus complex约含8种,特产中国.虽然其种类不多,但是不同的研究者分类结果有很大差异.通过对其花粉形态进行研究,结果表明:1)花粉形态均为椭圆球形,具3沟,表面有大小不等的网眼;2)心叶碎米荠Cardamine li mprichtiana与其近缘类群异堇叶碎米荠C.violifolia var.diversifolia的花粉在表面纹饰上差异很大,不能将两者划分为同一个属;3)心叶碎米荠和大叶葱芥Alliaria grandifolia的花粉明显比诸葛菜属的种小,能否作为该属的成员尚需进一步研究.Orychophragmus violaceus complex, containing ca. 8 species, is endemic to China. This complex is revised by several researchers and its taxonomical treatments are quite different between each another. Pollen morphology of the species Orychophragrnus violaceus complex, viz. O. violaceus, 0. diffusus, 0. hupehensis, 0. taibaiensis, Cardarnine limprichtiana, C. violifolia var. diversifolia and Alliaria grandifolia, is observed by Light Microscope （LM） and Scanning Electron Microscope （SEM）. The results are shown as following： 1） Pollen shape of all samples is ellipsoid with tricolporate apertures, and the surfaces are reticulate with lumina. 2） Pollen grains of C. limprichtiana are different from its related taxa, viz. C. violifolia var. diversifolia. They should be placed to different genus. 3） Pollen grains of C. lirnprichtiana and A. grandifolia are significantly smaller than that of the species of the genus Orychophragrnus. The generic position of these two species should be further researched.
