Anatomical characteristics of the leaves and stems of 9 species of the genus Lonicera from Caprifoliaceae family in Iran

The genus Lonicera (Caprifoliaceae), introduce with 9 species in Iran. The main purpose of this study was to analyze leaf and stem anatomical characters of the members of the genus Lonicera and also evaluating the systematical efficiency of these features. In this study, collected the plant samples to study the anatomical structure of the species, Then used method of cutting and colouring manually at the laboratory. In this study, used light microscope for imaging the anatomical structure of the leaves and stems.Although were considered of various anatomical characters differences between species bu t it seem anatomically character could not distinct exact boundaries between the species .The results obtained from this research confirmes usefulness this characters for identification of the genus. Species could not separate from each other by means of anatomical characters Concurrent use anatomical trait with other taxonomical character could possible distinct exact boundaries between the species . In addition to providing anatomical photos of the species and the species distinguishing characters were presented.
