TAILIEUCHUNG - Pollen morphology of the Turkish Romulea Maratti (Iridaceae)
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. | Turk J Bot 31 (2007) 171-182 © TÜB‹TAK Research Article Pollen Morphology of the Turkish Romulea Maratti (Iridaceae) Serap IfiIK1, Emel OYBAK DÖNMEZ2,* 1 Hacettepe University, Department of Secondary Science and Mathematics Education, 06800, Beytepe, Ankara - TURKEY 2 Hacettepe University, Department of Biology, 06800, Beytepe, Ankara - TURKEY Received: Accepted: 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.
