Abstract

Pollen morphology of the Turkish Romulea Maratti taxa (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 (L.) Seb. & Mauri var. crocea (Boiss & Heldr.) Baker and var. leichtliniana (Heldr. ex Hal.) Bég., growing sporadically in south-western Turkey, the existence of pollen type variability (monosulcate, disulcate, trisulcate, trisynsulcate, tetrasulcate, penta-aperturate (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 (bands are free or joined), operculate with 1 band (band is straight or curved), operculate with a circular band, or occasionally insulate.
