Palynological characteristics of 30 Salvia taxa in sections Hymenosphace and Aethiopis from Turkey were investigated by light and scanning electron microscopy. S. aethiopis (sect. Aethiopis) has the smallest pollen while S. blepharochlaena (sect. Hymenosphace) has the largest pollen. | Turkish Journal of Botany Turk J Bot (2013) 37: 1070-1084 © TÜBİTAK doi: Research Article Pollen morphology of Hymenosphace and Aethiopis sections of the genus Salvia (Lamiaceae) in Turkey 1, 2 3 4 5 Hülya ÖZLER *, Sevil PEHLİVAN , Ferhat CELEP , Musa DOĞAN , Ahmet KAHRAMAN , 2 6 4 Ahter YAVRU FİŞNE , Birol BAŞER , Safi BAGHERPOUR 1 Department of Biology, Faculty of Arts and Sciences, Sinop University, Sinop, Turkey 2 Department of Biology, Faculty of Sciences, Gazi University, Ankara, Turkey 3 Department of Biology, Faculty of Arts and Sciences, Nevşehir University, Nevşehir, Turkey 4 Department of Biological Sciences, Middle East Technical University, Ankara, Turkey 5 Department of Biology, Faculty of Arts and Sciences, Uşak University, Uşak, Turkey 6 Department of Biology, Faculty of Arts and Sciences, Bitlis Eren University, Bitlis, Turkey Received: Accepted: Published Online: Printed: Abstract: Palynological characteristics of 30 Salvia taxa in sections Hymenosphace and Aethiopis from Turkey were investigated by light and scanning electron microscopy. S. aethiopis (sect. Aethiopis) has the smallest pollen while S. blepharochlaena (sect. Hymenosphace) has the largest pollen. The basic shape of the pollen grains in most taxa is suboblate, oblate-spheroidal, or prolate-spheroidal to spheroidal; however, subprolate pollen grains are occasionally are found in S. cassia of sect. Aethiopis. Hexacolpate pollen is dominant in all studied taxa, but heptacolpate and octacolpate pollen grains are mixed together in S. palaestina (heptacolpate, 20%) and S. candidissima subsp. candidissima (heptacolpate, 2% and octacolpate, 40%). The exine sculpturing is bireticulate (the common type) or reticulate-perforate. The bireticulate and the reticulate-perforate sculpturing patterns can be divided into subtypes according to the number of primary lumina. Taxonomic .
