Morphological and Anatomical Characteristics of the Species Paliurus spina-christi

In plants and all living beings, the fundamental influence comes from ecological factors that operate simultaneously and in a complex manner. The influence of these factors is expressed in the morphological and anatomical features of the vegetative organs of plants, especially the leaves, which are among the most delicate organs where a series of adaptations occur. Although biological science today recognizes approximately 500,000 plant species, they differ from each other morphologically, anatomically, and genetically because they live in different life conditions and circumstances. Understanding the morphological‒anatomical characteristics of plants is highly important for determining their taxonomic and ecological adaptability. This connection between the morphological-anatomical structure of vegetative organs, especially leaves, and external factors has been addressed by many authors: Lakusiç (1962), Greb (1957), Pavlov (1965), Hoxha (1995), Mustafa (1995), and others. To obtain a clearer picture of the impact of ecological factors on the morphological and anatomical characteristics of vegetative organs of plants, we conducted research on the anatomical structure of leaves from different insertions: upper (E) and middle (M) of the plant species Pailurus spina Christi.
