The genus Rubia L. includes valuable species in terms of important agricultural, industrial, and pharmacological characteristics. Red dye obtained from the roots of Rubia tinctorum L., naturally found in the flora of Turkey and known as common madder, has been used as the source of a natural dye since ancient times. In this work, a preliminary report is given on anatomical and palynological traits of R. tinctorum distributed in the Aegean Region of Turkey examined by light and scanning electron microscopy. In the root anatomy, the cortex composed of multilayered parenchyma cells, the vascular tissue organized in collateral vascular bundles, 1(-2)-rowed ray cells, and the pith with a cavity at the center are observed. In the leaf anatomy, the bifacial and amphistomatic leaf, the dorsiventral mesophyll with one layer of columnar palisade parenchyma cells and a few layers of irregularly organized spongy parenchyma cells, and the midrib with a large collateral vascular bundle surrounded by parenchymatous bundle sheath cells are recognized. Pollen grains are shed as monads, small, mostly spheroidal in equatorial view, generally hexacolpate and have a microechinate-perforate exine ornamentation.
