ABSTRACT Pollen grains of seven Jasione (Campanulaceae) taxa from Turkey were investigated: J. heldreichii Boiss & Orph., J. idaea Stoj., J. montana L., J. supina subsp. supina, J. supina subsp. pontica, J. supina subsp. akmanii, and J. supina subsp. tmolea. Four of the investigated taxa were in the VU (vulnerable) category and one is in the LC (least concern) category (categorized by the International Union for Conservation of Nature). The basic shape of the pollen grains was prolate-spheroidal and oblate-spheroidal; the apertures vary from triporate- to tetra-porate. The sculpturing pattern of exine was microechinate. Two types were recognised according to the pollen shape. Type I is prolate-spheroidal, whereas Type II is oblate-spheroidal. This research will be helpful to explain the relationships among the genera of Campanulaceae and provides insights for future phylogenetic research.

摘要 研究了来自土耳其的七个 Jasione（桔梗科）类群的花粉粒：J.heldreichii Boiss & Orph.、J. idaea Stoj.、J. montana L.、J. supina subsp。supina, J. supina subsp. pontica, J. supina subsp. akmanii 和 J. supina subsp。莫利亚。被调查的分类群中有四个属于 VU（脆弱）类别，一个属于 LC（最不关心）类别（由国际自然保护联盟分类）。花粉粒基本形状为扁长球状和扁球状；孔径从三孔到四孔不等。外壁的雕刻图案是微棘刺。根据花粉形状识别出两种类型。I 型是扁长球体，而 II 型是扁球体。
