Anthemis ekicii (Asteraceae) is described and illustrated as a new species from Tuz Lake in Aksaray Province in Central Anatolia. The new species belongs to the section Anthemis, and it is closely related to A. pauciloba var. pauciloba, from which it differs in stem, leaves, and capitulum features. Diagnostic characters, description, detailed illustrations, ecology, IUCN conservation status, and pollen and seed morphology are presented in this study.

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. As a result of the phenetic analyses, the polar axis, equatorial axis, colpus length, and apocolpium were found to be significant …
