Scorzonera L. taxa

Pollen morphology of the 13 taxa of Scorzonera L. (Asteraceae) from Turkey was investigated by using light(LM) and scanning electron microscopy (SEM). As a result of LM and SEM observations, it was found that the pollen types are generally isopolar, radially symmetric, triangular in polar view, and lophate, with lophae ornamentations that are echinate-perforate and an exine thickness ranging from 6.99 to 11.82 μm.
