At this study, two species of genus Equisetum L. have been recorded, that they were: Equisetum telmateia L. and Equisetum ramosissimum Desf. E. ramosissimum Desf. was recorded for the first time in Lattakia. The morphological features were used to separate two species: ( number of the scaly leaves in the node area, shape of the sheath, and number of its teeth, number of the grooves at the stem, length of the strobilus and its color, length of the lateral branches). This study showed that: the spores had three coats, the exosporium rounded by the spore like bars with a wide terminal that called: elaters. Also showed obvious difference in measurements the strobilus and the shapes of sterile and fertile stem.

أظهرت دراسة جنس المنتعش Amaranthus L. في بعض المواقع في اللاذقية وجود 5 أنواع وهي: Amaranthus viridis L. , Amaranthus blitoides S. Wats., Amaranthus retroflexus L., Amaranthus palmeri S.Wats, Amaranthus sp. . النوع Amaranthus palmeri يُسجّل لأول مرة في سوريا، أما النوع Amaranthus viridis فقد كان مسجلاً في فلورا سوريا ولبنان كمرادف لنوع آخر هو Amaranthus lividus بينما سُجّلا في فلورات أخرى كنوعين منفصلين، والنوع Amaranthus sp. قد يرجع لهجين شكَّل نوعاً مستقلاً بالنظر إلى اختلافه كلياً عن الأنواع الأخرى المعروفة جيداً. . بينت دراسة حبات الطلع أنها من النمط الكروي عديد ثقوب الإنتاش Polypantoporate عند جميع الأنواع المدروسة، مع اختلاف بسيط بالأبعاد، واختلاف بعدد فتحات الإنتاش على الوجه المرئي للحبة حيث تراوح متوسط عدد الثقوب على الوجه الواحد بين 14 ثقباً عند Amaranthus retroflexus، و24 ثقباً عند Amaranthus palmeri. وقد بينت نتائج دراسة مسام الورقة وجود أربعة أنماط من المسام هي: Anisocytic, Anomocytic, Isotricytic, Tetracytic، حيث اشتركت الأنواع الخمسة بالنمط Anomocytic، ولوحظ وجود أكثر من نمط في الورقة الواحدة في كل الأنواع عدا النوع الجديد. وبينت الدراسة الإحصائية درجة القرابة بين الأنواع المدروسة، وأن النوع الجديد كان أقرب إلى النوع Amaranthus palmeri.
The results of studying the morphological characteristics of the flower, fruit, pollen grains, and seeds between some of Hypericum genus species, show that there are relevant morphological differences among the studied species, which can be considered as taxonomical criteria for distinguishing the studied species of Hypericum genus from each other.
This study was performed on three types of the genus Fumaria. The measurements were taken from the various parts of the flower petals, Sepals , the stamina and fruits. Also, an anatomical study was conducted of the root and stem. The shape and dia meter of pollen grains, the diameter of germination hole and the number of total pollen grains were studied. It was observed that the longest flowers and fruits in the specie F.capreolata.
Family Vespidae considered as Widespread globally and belong to the order Hymenoptera called wasps, It contains about 5000 species belong to six subfamilies. Members of this family differ in terms of style of living and life cycle and the type of diet. Colors overlap between the black and yellow or red, yellow or three together. This study examined six species belong to the four genera (Vespa, Vespula, Poistes, Delta) and three sub-families are: Sub.Fam. Vespinae, Sub.Fam. Polistinae, Sub.Fam. Eumeninae, gathered from many different areas of the province of Latakia environment (15 area) from altitudes ranging from sea level to a height of 1000 meters, over a period of time it extends from April through October of 2015.
