The chromosome number, karyotype and pollen analysis of Turkish endemic species Tordylium elegans (Boiss. & Bal.) Alava & Hub.-Mor. are reported in this paper for the first time. The somatic chromosome number is determined as 2n = 4x = 16. It is a tetraploid species and the basic chromosome number is x = 4. Haploid karyotype formula is 4sm + 3m + 1T. The pollen morphology of T. elegans was examined under light and scanning electron microscope. Pollen of T. elegans are radially symmetrical, isopolar, tricolporate, perprolate and equatorially-constricted.
