أكدت الدراسة التصنيفية لجنس Ornithogalum L. الصلصال ( نجم بيت لحم ) تسجيل 4 أنواع تابعة له هي: O.narbonense L., O.montanum Cyr., O.umbellatum L., O.ulophyllum Hand.. لأول مرة في منطقة جبلة، و تم وضع قاعدة بيانات مورفولوجية تضمنت ( الشكل الحياتي - و الأبصال - و البصيلات المحيطة بالبصلة - و الأوراق– و وجود الخط الأبيض على الوجه العلوي للورقة – و الخط الأخضر على الوجه السفلي للتبلات - و الأسدية – المدقة – و الثمار – و البذور - مع نمط حبات الطلع و أبعادها، و تحديد نمط الثغور ), و ربطت هذه الصفات باستخدام برنامج الإحصاء Statistica للحصول على شجرة النسب Dendrogram التي بينت وجود 3 عناقيد, عنقود مشترك للنوعين O.narbonense, O.ulophyllum، بينما انفرد كل من النوعين O.umbellatum O.montanum, بعنقود خاص به, و وضع مفتاح تصنيفي للتميز بين الأنواع المدروسة.
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 database 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.

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.
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.
Five species of the genus Poa L. from (Poaceae) were collected and studied in
Lattakia, they are : P. annua ، P.infirma ، P. pratensis ، P. bulbosa ،P. nemoralis.
This study put data base of the morphological features which included : habit, leaves
,
ligule, the structure of the inflorescence , spikelet, floret, micro-morphological
characteristics which contained the epidermal structure of abaxial leaf surface, and the
difference between costal and inter-costal zones of the 5 species, studying of pollen grain
clarified the similarity in shape but there was a simple difference in measurements . Then ,
data from micro and macro morphological study were used to made a Dendrogram by
using Statistica . The dendrogram showed the linkage of two annual species P. annua ،
P.infirma in a cluster , every one of three another species had his specific cluster , P.
nemoralis was closer to the annual species .
