POLLEN MORPHOLOGY OF SOME TURKISH ENDEMIC HELICHRYSUM GAERTNER SPECIES (COMPOSITAE)

N.M. PINAR AND E. OYBAK DONMEZ*

Abstract: Pollen morphology of 6 endemic taxa in the genus Helichrysum Gaertner (Compositae) has been investigated using light and scanning electron microscopy. The pollen grains of all the Helichrysum taxa are similar in that they are tricolporate with spines and rugulate ektexine sculpturing. They are spheroidal, prolate-spheroidal or oblate-spheroidal in shape.
