Abstract: The present study included comparative anatomical study for 10 cultivated species of the family Compositae collected from public gardens for different region of Baghdad city, these species are : 1 - Aster amellus L. )استر(2 - Cosmos sulphureus Cav. )كوزموز(3 - Dahlia variabilis Willd. )داليا(4 - Gaillardia pulchella Foug. )عنبر كشمير(5 - Gazania splendens Hork. )ك ا زنيا(6 - Gerbera jamesonii Hook. )جربي را(7 - Helichrysum bracteatum Vent. )ورد الكاغد(8 - Tagetes erecta L.)جعفري(9 - Tagetes patula L.)قديفة(10 - Zinnia elegans Jacq. )زينيا(The study dealt with some anatomical characters and study are Compared for the first time to these species in Iraq.The study included the features of ordinary epidermal cells leaves stems, and involucre bracts, and also stomatal complexes, Actinocytic type was recorded as new founding in the species Aster amellus. The study included cross sections of the roots and also exposed the constituent tissues of it and the varies in the thickness of epidermis cortex, vascular cambium as well as the arrangement of phloem which have an important role in the studies species.studying of cross sections of stems showed important taxonomic characters like thickness of epidermis, presence or absence of collenchymatypes and rows number, characteristic of the vascular bundles in terms of forms and numbers, therefor the species were divided into groups.The vascular cylinder characters also gives prominent anatomical characters importance in terms of being continuation or intermittent.The study of vertical section of leaf showed important anatomical characteristic like thickness of upper and lower epidermis thickness of palaside and spongy layer, layers number and from of vascular bundles. The venation system of was investigated and compared between species.The study included characteristic of cross sections of petiole in terms of thickness of cuticle, epidermis and collenchyma number and forms of vascular bundles. The vertical sections of involucre bracts also studied.Indumentum of different parts of plant (leaves, stems, bracts and fruit) are also studied in details, glandular hairs and eglandular hairs where studied in terms of cells number, lengths, apexes and bases forms and other characters in addition to papillae which occur in some species. Petals venation were investigated and compare between species.The study also resulted in the presence of internal secretory structures, the study showed the locations of these structures, dimensions and the method of formation to these structures which gave an important anatomical character. The study showed the presence of crystal, which differ in the, forms and sizes which contributed to the isolation of species it was the first time note sphaerocrystals (Inulin crystal) in tuberous root cortex of Dahlia variabilis the prismatic crystals of the type styloid in root cortex of Gerbera jamesonii.The study showed results and characters and these were presented for the first time. Investigation include field photographs of studied species and plates of sections which studied in different plant parts in addition to many tables.

Abstract: تناولت الدراسة الحالية دراسة تشريحية مقارنة لتسعة مراتب من العائلة القرعية Cucurbitaceae المستزرعة والبرية والتي زرعت في الحديقة النباتية لكلية التربية للعلوم الصرفة ابن الهيثم والمراتب هي : 1 - Citrullus colocynthis Schrad2 - Citrullus vulgaris Schrad3 | The present study included comparative anatomical study for nine taxa of Cucurbitaceae family for cultivated and wild types, which were planted in the garden of College of Education for Pure Sciences/ Ibn Al - Haitham. These taxa included : Citrullus colocynthis Schrad, Citrullus vulgaris Schrad, Cucumis melo Linnaeus, Cucumis melo var.flexuosus Naudin, Cucumis sativus Linnaeus, Cucurbita maxima Duchesne, Cucurbita pepo Linnaeus, Lagenaria siceraria (Mol.) Standl, Luffa cylindrica (Linnaeus) M. Roem. This study focused on some the anatomical characterization as compared study for the first time to these taxa in Iraq. This study included the features of ordinary epidermal cells, leaves petioles, stems, pedicles and sepals of the studied taxa. The results found the appearance of stomata in the stems and petioles in straight line as adjacent planar shape to the epidermal cells and not scattered as found in the leaves, this result was seen for the first time in the current taxa. Furthermore, the stomata have been shown in pedicel and sepals in same type as the stomatal complexes in leaves. The importance of phenotypic variation for the length and types of eglandular trichomes and the presence or not of glandular trichomes were found to carry out the role of indumentum in the different isolated taxa. Additionally, this study included the examination of the cross sections of the roots and also exposed the constituent tissues of it, the variation in the thickness of epidermis, cortex, vascular cambium as well as the arrangement of phloem cells have an important role in the studied taxa. The cross sections of stems, leaves petioles and pedicles showed shape and studied a significant role in the studied taxa and split them into groups.Moreover, this study concluded that the following of above sections from the outside into the inside has an important role to find out their constituent tissue. Thus the results of the study clarified the importance of epidermis tissue through the explanation of the outer and inner tangential walls of their cells and the variation in their dimensions, thickness and kind of stomatal complexes; therefore it has been given the importance of those features in the studied taxa in this study. Cortex tissue showed an extension of angular collenchyma and chloronechyma from stem to pedicel and have shown variation in the thickness in these two layers which was useful in the classification of studied taxa. Vascular tissues differed in the shape of vascular bundle, the number of rows and xylem units and the arrangement of the internal phloem, and all of those characteristics have helped in the studied taxa. In addition, the vascular tissues helped to find their arranged in the stems and found as vascular cylinder shape, while in the petioles and pedicel shown as vascular ribbons were which took the shape of sections petioles and pedicel. The medullar cells and medullary rays have been studied and also their similarity in the morphological characterization and function. Moreover, the anatomical features of the vertical sections of the laminae of leaves in mesophyll tissue have been examined, in the thickness of palaside and spongy layers in midrib, the variation in number and arrangement of vascular bundles have an important role in the studied taxa. In the current study, the ordinary and petal leaves venation and the type of venation have been studied in the studied taxa. Moreover the vertical sections for sepals were examined and also their similarity with laminae of leaves which was useful for studying the constituent tissues of some parts such as pedicel and sepals and anatomical features; and all of the studied characterization helped to study the vegetative parts through following them in studied taxa.
