A multivariate analysis was carried out using the Gover’s general similarity coefficientand UPGMA based on 3 qualitative and 8 quantitative pollen characters for 43 taxa belonging to 30 genera and 19tribes. In all of the taxa studied, the pollen grains were generally small or medium-sized, tricolpate, except in Matthiolalongipetala, with an inconspicuous aperture. The shape varied from prolate-spheroidal to perprolate. The exineornamentation was microreticulate, reticulate, or macroreticulate. In some species, reticulate ornamentation was foundtogether with microreticulate, and in some others, with macroreticulate ornamentation. It was seen that some taxabelonging to some genera placed near each other in the dendogram partially supported some tribes, such as Brassiceae,Alysseae, Sisymbrieae, and Camelineae. It is notable that some closely-related tribes were placed near each other on thedendrogram, which partially supports some previous molecular studies. In addition to exine ornamentation, the pollensize, shape, sexine and nexine thickness, and colpus length were the most useful characters. These characteristics can beused to identify and distinguish some genera, species and partly tribes within the family. They also provide detailedinformation on the pollen grains of some Brassicaceae taxa, some of which were studied herein for the first time, andthis knowledge will be useful for comparisons in future pollen studies.eninfo:eu-repo/semantics/openAccessBiyolojiBitki BilimleriArticle14110511810.46309/biodicon.2021.773419462054
