Abstract in English
This study contributes to the identification of plants in local flora for the
purpose of preparing accurate classification of Syrian flora by specialists
in plant classification. The objective of our research is - within this scopein
the morphological study of species belonging to Alopecurus L. This
study adds to the Syrian flora a new species (Alopecurus utriculatus
Sol.) from the family (Poaceae), tribe (Poeae). Besides, two another
subspecies of (Alopecurus myosuroides Huds.) were studied. They
are: A. subsp. Myosuroides and A. subsp. Tonsus. The study of
these 3 samples included macro – morphological features such as:
life form, leaf, ligule, inflorescence, glumes, lemmas, and flowers,
and the micro – morphological features which are: abaxial surface
of the leaf epiderm, and pollen grains. Macro – morphological
study proved that the 3 samples are totally different in ligule shape,
the shape and width of the cylindrical inflorescence, spikelet shape.
And the micro – morphological study showed the similarity in
epidermal structure in terms of the stomata pattern, , presence of
hooks and prickles, but different in silica type. Pollen grains were
elliptic and similar in the species and two subspecies.
