This paper was designed to analyze the petiole anatomical characteristics of six Hedysarum species in Turkey. Paraffine method was applied to obtain cross sections of petiole or handmade sections were used to made anatomical analysis. The cross sections taken from petiole of studied species had an epidermis layer with oval-rectangular shaped. There was a large median bundle in all examined species with smaller lateral two bundles. Collenchymatic tissue changeable from 4 to 8 layered was located in the corners of petiole especially over the vascular bundles in studied species. Multilacunar and trilacunar petiole types were detected to separate species each other. The pith region of petiole had oval shaped parenchymatic cells that in different size. The petiole anatomical characteristics of Hedysarum species were showed that the Subacaulia and Crinifera sections have trilacunar petiole type the most primitive type in Hedysarum genus however Multicaulia section has multilacunar type which is advanced one. In conclusion, the median and lateral bundles size and their patterns are the most constructive petiole anatomical character to separate Hedysarum species has been determined. [ABSTRACT FROM AUTHOR]
