Abstract
The current study examined the survey of the Gymnosperm plant and Angiosperm plant of dicotyledon and monocotyledon wild during the study period (2020- 2022) in the area of Najaf desert, there are (257) species belong to (47) families. the dicotyledone species (215) beloing to (40) families, the monocotyledon species (41) beloing to (6) families. All these have been scientifically classified. So their duration and economic importance (medical, toxis, nutritional, forage, artificial, harmful, aromatic, ornamental, fuelplant or other uses) was tabeled. Moreover, their geographical distribution the districts of Iraq and the study results statistics have shown that the most of the collected species are herbal plants totalling (223) wild species out of (257) wild species, the shrub species it amounts to (28) wild species where as the number of woody species of tree is (2) as the number of parasitic species is (4). As for the economic plants and their significance, the current study found that most of species were medical plants and used as forage and fuel, some of them were toxic, ornamental, aromatic plants. it also study the floristic composition ,there are dominating to Compositae ,Graminae and Chenopodianaceae families of (44) species ,(31)species ,(31)species previosly .then the Papilionaceae families with (22)species ,then the Brassicaceae family with (20) species so the dominating genus was Astragalus, , with (7)species ,then ,launaea and Plantago each genus with(6) species ,then the Euphorbia with (5) species , the plant communities was studied ,there are dominating to wild species as Haloxylon salicornicum , Zygophyllum coccenium,Cornulaca leucoantha and Tamarix species sp. .
