Summary:The present study deals with the anatomical properties of Aethionema dumanii, which is an endemic species growing in Salt Lake (Konya). The stem cross-sections have a single-layered epidermis, parenchymatous cortex, vascular bundles, and pith cells. An equifacial mesophyll type was observed in the leaves with multiple-layered palisade tissue, but the spongy parenchyma was reduced. Vascular bundles were smaller. The cross-sections of fruit had single exocarp, 3- or 4-layered mesocarp, and single-layered endocarp. Transverse sections of the seed showed an epidermis, palisade tissue, endosperm, and embryo. The anatomical characteristics of A. dumanii has been found to have valuable taxonomic importance. Bu çalışma, Tuz Gölü’nde yayılış gösteren endemik tür Aethionema dumanii’nin anatomik özelliklerini ele almaktadır. Gövde enine kesitleri, tek tabakalı epidermis, parankimatik korteks, iletim demetleri ve öz hücrelerine sahiptir. Yapraklarda, çok tabakalı palizat parankimasına karşın sünger parankiması indirgenmiş ekvifasiyal tip mezofil gözlemlenmiştir. İletim demetleri küçüktür. Meyve enine kesitleri tek bir ekzokarp, 3 ya da 4 tabakalı mezokarp ve tek tabakalı endokarpa sahiptir. Tohum enine kesitleri bir epidermis, palizat dokusu, endosperm ve embriyodan oluşmaktadır. A. dumanii’nin anatomik karakterlerinin taksonomik önemi olduğu belirlenmiştir.
