    Abstract
    The pollen morphology of six species belonging to six genera of Boraginaceae in Qatar have been investigated by LM and SEM. The examined species proved to be eurypalynous, having different morphological types and can be recognized individually from their pollen grains. The only exception is Lappula spinocarpos and Echiochilon kotschyi, where their pollen grains are morphologically similar. In general, the pollen grains are small and isopolar. There are five different types of apertures encountered in the examined species. These types range from tricolporate, 8-colporate and 6 to 8 colpate, pollen grains. Clear variations were also observed in sexine ornamentations, particularly around apertures.
