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.

    Pollen morphology of 36 species representing 14 genera within the tribe Rhinantheae in the family Orobanchaceae was studied and illustrated with light microscopy (LM) and scanning electron microscopy (SEM). Five major pollen types were recognized on the basis of exine ornamentation. Within these...

    Recent molecular studies have elucidated the phylogeny of Compositae tribe Arctotideae, and found it to contain two, well supported, monophyletic subtribes, Arctotidineae and Gorteriinae, as well as some polyphyletic and problematic genera. On the basis of this new information, it may now be...
