In this investigation, the macromorphological, micromorphological, anatomical and palynological properties of some Aethionema species (Ae. arabicum, Ae. cordatum, Ae. armenum and Ae. karamanicum) which belong to Brassicaceae family were exhibited. In macromorphological studies, the heights of stem, the length of leaf and flower and fruit dimensions of species have been given and their descriptions are expanded. In micromorphological investigations we determined that the fruit ornamentation of studied species is scabrous in Ae. arabicum, verrucose in Ae. cordatum, papillate in Ae. karamanicum, smooth in Ae. armenum. Also the micromorphological seed characteristics of species have determined that are essential for species differentiation. In anatomical studies, the structural characteristics of cross sections of root, stem and leaf of species have shown taxonomical significance. All examined species have reticulate pollen ornamentation but their murus are different each other in point of their palynological features.Original Abstract: Bu calismada, Brassicaceae familyasinda yer alan Aethionema cinsine ait (Ae. arabicum, Ae. cordatum, Ae. armenum ve Ae. karamanicum) bazi taksonlarin makromorfolojik, mikromorfolojik, anatomik ve palinolojik ozellikleri ortaya konulmustur. Makromorfolojik calismalarda turlerin; govde boyu, yaprak uzunluklari ile cicek ve meyve gibi yapilarina ait olcumleri verilmis ve deskripsiyonlari genisletilmistir. Mikromorfolojik arastirmalarda ise arastirilan turlerin meyve ornamentasyonlarinin Ae. arabicum'da skabroz, Ae. cordatum'da verrukoz, Ae. karamanicum'da papillali, Ae. armenum'da duz oldugu belirlenmistir. Ayrica turlerin tohum mikromorfolojik karakterlerinin, turlerin ayriminda onemli bir ozellik oldugu tespit edilmistir. Anatomik calismalarda, kok, govde ve yaprak enine kesitlerinin yapisal ozellikleri taksonomik onem gostermistir. Palinolojik ozellikleri acisindan arastirilan turlerin tamaminda polen ornamentasyonu retikulattir fakat muruslari birbirlerinden farklidir.
