Palynological characters

In the current study morphological, palynological, and molecular characters were compared and discussed with its closely related species. The new species is similar to D. crinitus with fimbriate corolla, linear, acuminate, ± rigid leaves. Also similar to D. vanensis with fimbriate corolla, linear, acuminate, ± rigid, curved divaricate leaves.

In this study, three new hybrids from the genus Cirsium are described for the first time. Cirsium ×nezaketiae Yıldız, Dirmenci & Arabacı, C. ×kelkitensis Yıldız, Arabacı & Dirmenci, and C. ×erzincanicum Yıldız, Dirmenci & Arabacı are investigated in detail morphologically, palynologically, and molecularly. The hybrid individuals were detected on field trips due to their intermediate morphological characters. Their morphological properties were analyzed to compare with their parents.

Palynological characters of 20 taxa belonging to the Turkish subgenus Cyanus were studied in details using light and scanning electron microscopy. Pollen grains of the subgenus Cyanus were tricolporate or syncolporate, subprolate or prolate-spheroidal, 26.15 to 53 µm in polar size, 22.84 to 46.86 µm in equatorial size, isopolar, and radially symmetrical. The only type of pollen grain ornamentation observed was scabrate-perforate. Principal component analysis and cluster analysis were performed to investigate the relationships of the studied Cyanus taxa.

The tribe Nigelleae Schröd. (Ranunculaceae) worldwide distribution has been studied taxonomically, based on morphological, palynological and seed morphological characters, as well as chromosome counts. Extensive field works have been carried out in Turkey, Greece, Iran, Syria, Lebanon, Portugal and in Northern Cyprus. Moreover, the specimens of major herbaria in Turkey, Ukraine, Russia, Syria and Iran as well in Europe have been examined.

This paper reports the morphological characters of 18 Iranian species of the genus Alchemilla using light and scanning electron microscopy. The pollen grains are monad, radially symmetrical, isopolar, or subisopolar, small to medium in size, triand tetracolporate, rectangular to cylindrical (from equatorial view) and triangular to circular (from polar view) in outline and prolate-spheroidal to subprolate and prolate in shape.
