Abstract
This research dealt with study of cladistics taxonomy of five species related to the genus Rumex L. and Polygonum L. from family polygonaceae in Iraq by using Mesquite software V.2.75. This research support strongly delimiting the species P. aviculare L. and P. lapathifolia L.as suggested in floras publication while R. dentatus L. is setted in single group whereas R. vesicarius L. and R. conglomeratus Murray were included in the same group. Also, this study involved characteristics of shape, dimensions, color, and ornamentation of seeds and fruits as the seed forms were ranging from lenticular to trigonous. In terms of size calculations, the seeds of R. vesicarius was recorded the higher range (4.0- 4.5) mm in length while, P. aviculare recorded the lowest (1.5-1) mm in length. However, the shape was lenticular in P. lapathifolia and trigonous in the remaining species. Color of seeds and surface ornamentation is recognized. fruits shape is an important characters in identification of selected species as two groups are distinguished: persistent tubercules tepals which are spine teeth in R. dentatus and tongue like shape in R. conglomeratus, the second group is persistent tepals which are papery in P. lapathifolia, biconvex in P. aviculare and cordate to winged as in R. vesicarius beside that, colors, dimensions and surface nature is also recorded.

Summary
Number of publications suggested including features for identification purpose the genus Rumex is in the tribe rumiceae and [11,12,13,27].Numerical taxonomy is proved. Polygonum in polygoneae together in the to be helpful in delimiting species more than polygonaceae family which is from conventional methods. The family is generally 30 to 49 of number of global research on fruit genera with about 750 species globally and morphology of polygonaceae but there is still approximately 33 species in Iraq lacking data about Iraqi buckwheat family. [10,11,14,15].The genus Rumex has the the present study aims to evaluate the highest diversity within Iraqi buckweed family taxonomic effect of cladistics taxonomy to with ten species distributed throughout Iraqi delimit the studied species beside districts principally towards the mountain morphological data of the seeds and fruits of regions. The diversity of according to their availability in the lab
