Pollen morphology of 20 species of the Veronica were investigated using Light Microscope (LM) and Scanning Electron Microscope (SEM). Different palyno-morphological features including; pollen ornamentation, colpus ornamentation, size of polar and equatorial diameter, P/E ratio, exine thickness, and size of colpus were observed. The study revealed that the pollen grains of the studied Veronica species were in all cases tricolpate, radially symmetrical and isopolar, oblate-spheroidal or prolate spheroidal. The surface pattern of the exine varied from striato-reticulate and striatomicroreticulate to microechinate-perforate, which allows recognition of three homonymous types of pollen grains.eninfo:eu-repo/semantics/closedAccessLight MicroscopyPlantaginaceaePollen MorphologyScanning Electron MicroscopyTurkeyVeronicaArticle532122362-s2.0-85141992057Q2WOS:000748416200002Q410.11646/phytotaxa.532.1.2
