Taxonomic importance of leaf anatomical characters for the genus Alopecurus L. (Poaceae)

Tiller leaf anatomical features of nine Alopecurus species collected from high mountainous areas in Turkey were evaluated the present study. Detailed descriptions studied taxa and an identification key generated using are given. Clustering principal coordinate analysis (PCA) methods applied based on a total 14 characters. Anatomical differences between detected characters taxonomic interest identified this genus. With clustering analyses, UPGMA tree was obtained to show relationship studied. Based results PCA, arrangement adaxial sclerenchyma cells, number ribs, abaxial strands, size epidermal cells vascular bundles designated as most reliable separate species.
