Özet:

Distributed in Turkey Rumex crispus L., Rumex patientia L., anatomical features of Rumex obtusifolius species were comparatively investigated in this study. For anatomical studies, cross-sections were taken from root, stem and leaf. In addition, superficial sections were taken from the leaf and stomata index and stomata features were determined. Similarities and differences of taxa are revealed. There were druse crystals at the root of the R. obtusifolius plant. The radial-shaped vascular bundles in the root of R. crispus had 4-5 arms. Glandular hair was found only in the body of R. obtusifolius. It is also characteristic that vascular bundles were scattered in the stem of this species. There was cuticle in the stem of R. crispus. Stem corner numbers of taxa can also be seen as a distinguishing feature in terms of species. R. crispus was 10, R. obtusifolius was 8, R. patientia was 14 cornered. The number and type of collenchyma layer in the stem of the species were also different Outward bulge was detected in the middle-vascular region of leaves of the taxa. This bulge was less pronounced in R. crispus and the most prominent in R. obtusifolius. At least the number of stomata was observed on the R. obtusfolius leaf. Leaf epidermis cell walls were wavy in R. patientia.
