Abstract :Pollen morphology of the Turkish Romulea Maratti taxa insert ignore into journalissuearticles values(Iridaceae); was examined using light and scanning electron microscopy. The taxa are similar in some aspects, such as pollen size and spinulate-microperforate exine sculpturing. Most taxa are monosulcate; however, in 2 taxa, R. bulbocodium insert ignore into journalissuearticles values(L.); Seb. & Mauri var. crocea insert ignore into journalissuearticles values(Boiss & Heldr.); Baker and var. leichtliniana insert ignore into journalissuearticles values(Heldr. ex Hal.); Bég., growing sporadically in south-western Turkey, the existence of pollen type variability insert ignore into journalissuearticles values(monosulcate, disulcate, trisulcate, trisynsulcate, tetrasulcate, penta-aperturate insert ignore into journalissuearticles values(with longer and shorter sulci);, and monoporate); from single pollen sacs was recorded for the first time. In addition, aperture morphology was found to be variable within most taxa; operculate with 2 bands insert ignore into journalissuearticles values(bands are free or joined);, operculate with 1 band insert ignore into journalissuearticles values(band is straight or curved);, operculate with a circular band, or occasionally insulate.
