تم إجراء هذه الدراسة على ثلاثة أنواع من نبات الشاهترج Fumaria و أخذت القياسات لأجزاء الزهرة المختلفة من بتلات و سبلات و أسدية و ثمار، و أجريت أيضاً دراسة تشريحية للجذر و الساق و دراسة حبات الطلع من حيث الشكل و قطر الحبة و قطر ثقب الانتاش و عدد حبات الطلع الكلي. لوحظ أف أطول الأزهار و الثمار كانت عند النوع F.capreolata.
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 diameter 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.

This study was performed the existence of the species Datura innoxia Mill. in the Syrian
flora. Also the morphological study results showed that the plant is a gray greenish herb,
its stem is erect. Leaves are simple, alternated, oval, its angle is
turbinated to the out. The
root is sphenoid.
The flower is regular. The fruit is capsule, and the seed is splay, have an excrescence.
The palynological study showed that the pollens are ellipticity, triad of germination lines.
Whereas, the anatomical study showed that the form of carrier packing take quadric side
type.
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.
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.

Taxonomic study confirmed of genus Ornithogalum L. (Star of Bethlehem)
recording 4 spices belonging to him are: O.narbonense L., O.montanum Cyr.,
O.umbellatum L., O.ulophyllum Hand.. for the first time in the Jableh region, The
morphology of the d
atabase was put included (Habit - bulbs - bulbest surrounding Balbs -
leaves- presence of the white line on adaxial of the leaf - the green line on abaxial of the
tepal - stamens - pistil - fruits - seeds - with type and dimensions of pollens and definition
the stomatal type) and linked these character by using Statistica for Dendrogram which
showed the presence of 3 clusters, cluster common of two spices O.narbonense,
O.ulophyllum, While an alone all of two spices O.umbellatum O.montanum, cluster of its
own, and put a taxonomic key to distinguish between studied species.
