ANATOMICAL DIFFERENCES OF THE TURKISH STUCKENIA B?RNER (POTAMOGETONACEAE) AND THEIR TAXONOMIC SIGNIFICANCE

摘要

Anatomical studies of the Stuckenia species occurring in Turkey were conducted. The results showed that thepresence or absence of interlacunar bundles and the stelar type were the most important in plant anatomical characters ofthe stem. The leaves of the all investigated species typically had uniseriate epidermis with a thin cuticle, aerenchyma wascomposed of arm-shaped chlorophyllous cells, similar to those found in the stem and the peduncle. Two lateral vascularbundles and a central vascular bundle are present in the leaves of all investigated species. However, the number of lateralvascular bundles can vary in S. pectinata according to leaf width and the fiber bundles are also present in the triquetrousleaves of this species.
