In this study, morphological, morphometrical, karyological and detailed pollen morphology of Ebenus haussknechtii endemic to Turkey was studied for the first time. In the morphologic study, some morphological and morphometrical features of the plant were observed and compared with the published findings in the Flora of Turkey. Karyogram and idiograms of the plant were also prepared. The chromosome number of E. haussknechtii was determined as 2 n = 14 and haploid karyotype formula 5 m + 1 sm + 1 M. Metaphase chromosome length ranged from 2.16 to 1.93 μm and the total haploid chromosome length was 17.90 μm. The results of the light microscope investigation of the pollen revealed that the pollen grains were radially symmetrical, isopolar, tricolpate and prolate. Measurement of the reticulum heterobrachate indicated their ornamentation to be reticulate.
