Abstract: تناول البحث الحالي دراسة بيئية لعدة مواقع من محافظة كربلاء المقدسة بين شهري شباط وايار ولسنتي 2013 و2014 من حيث نوع الترب والمجتمعات الاحيائية لهذه المواقع جمعت خلالها انواع مختلفة من النباتات تابعة لعائلات مختلفة ضمن ذوات الفلقة الواحدة وذوات الفلقتين اذ | The present work includes ecological study for different locations of the holy Karbala province between February and May and for the years2013, 2014, investigating soil kinds and communities in these locations. Different plant species of Monocots and Dicots were collected from variable soil kinds, such as sandy saline soil, loamy saline soil and sandy gravely soil. The species of Haloxylon salicornicum, Zygophyllum coccenium were dominant in the communities of sandy saline soil, Nitraria retusa, Juncus sp. and Halocnemum strobilaceum were dominant in loamy saline soil.Comparative anatomical study has been done for (30) Dicots wild species grown in these environments of Karbala province, as follow : a.Family : Aizooaceae1) Aizoon hispanicum L. b.Family : Chenopodiaceae2) Chenopodium murale L.3) Halocnemum strobilaceum (Pall.)M.Bieb.4) Haloxylon salicornicum (Moq.)Bunge ex. Boiss.5) Salicornia herbacea L.c. Family : Compositae (Asteraceae)6) Carthamus oxycantha M.B. 7) Launaea capitata (Spreng.)Dany 8) Launaea mucronata (Forssk.)Muschl. 9) Rechardia tingitana (L.)Roth. d. Family : Convolvulaceae10) Convolvulus oxypyllus Boiss. e. Family : Cruciferae (Brassicaceae)11) Diplotaxis harra (Forssk.)Bioss. 12) Sterigosella africana (L.)Boch. 13) Sterigosella grandiflora (Bnge)Bochantsev 14) Savignya parviflora (Del.)Webb. 15) Neotorularia torulosa (Desf.) Hedge & J. Leonard 16) Zilla spinosa (Turra)Prantl. f. Family : Cucurbitaceae 17) Citrullus colocynthis (L.)Schrad. g. Family : Geraniaceae18) Erodium laciniatum (Cav.) Willd.h. Family : Malvaceae19) Malva parviflora L. i. Family : Neuradaceae 20) Neurada procumbens L. j. Family : Nitrariaceae21) Nitraria retusa (Forssk.)Aschers.22) Peganum harmala L. k. Family : Papillionaceae23) Trigonella stellata Forssk. m. Family : Polygoniaceae 24) Rumex versicarius L. n. Family : Resedaceae25) Oligomeris linifolia (Vahl)Macbr.q. Family : Solaneaceae 26) Lycium barbarum L.r. Family : Tamaricaceae 27) Tamarix florida Bge.28) Tamarix macrocarpa (Ehrenb.)Bge.u. Family : Zygophyllaceae29) Fagonia glutinosa Del. 30) Zygophyllum coccenium L. The present research focused on many anatomical characters and studies comparatively, such as epidermis types, stomatal complexes, leaf venation, cross sections of root, stem and vertical sections of leaf blades. Different cross sections were shows variability cuticle thickness and epidermis, vascular cylinder tissues, collenchyma and sclerenchyma in different species studies. Variations were noticed among these tissues in the variable species.Thickness of cuticle epidermis of leaves were variable, and unifacial and bifacial mesophylls were noticed for the first time in some species studies. Some cross sections were obtained for scale leaves in Tamarix florida, Tamarix macrocarpa, Halocnemum strobilaceum, Haloxylon salicornicum and Salicornia herbacea.The anatomical characters of these plant parts has not been studied before for these species, at least for Iraqi specimens. The following species Launaea capitata, Oligomeris linifolia and Zilla spinosa were glabrous in all vegetative and reproductive organs. In time that the other species, Haloxylon salicornicum , Salicornia herbacea, Launaea mucronata, Reichardia tingitana, Strigosella grandiflora , Peganum harmala, Lycium barbarum, Tamarix florida and Tamarix macrocarpa were glabrous just in the vegetative parts, but hairy (pubescent) in the reproductive organs. The indumentums was variable in thickness within variable plant organs and parts, even on the lower and upper leaf surfaces. Different kinds of crystals were found and verified in the stems and leaves of different species. Size and density of these crystals were variable in variable locations of stem and leaf tissues.. Geographical distribution was investigated for all the studied species using Iraqi satellite maps by GIS program. Neotorularia torulosa was the most distributed species, and Rumex versicarius was the least distributed one. Schedules, schemes, illustrations and micrographs were presented for the different species studied in this work. Lastly results were discussed depending on available references and reasons.
