Brassicaceae, previously Cruciferae, is a flowering plant family that includes 338 genera and 3,700 species. Members of the family are economically important but domestically altered by humans. The taxonomic information of Parlatoria cakiloidea is ambiguous. Presently, no standard criteria to identify the species into simple entities for taxonomic, conservation and pharmacognostic studies. The study aimed to taxonomically identified  Parlatoria cakiloidea. Fourteen herbarium specimens of P. cakiloidea were examined from Salahaddin University using Unsupervised multivariate analysis. Principal component and hierarchical cluster analysis were constructed using software SIMCA-P (V.14.1 Umetrics Sweden). The multivariate analysis established the relationship (similarities and discrimination)  that existed. Parlatoria cakiloidea were found to be divided into four major groups   in Kurdistan region of Iraq. The information provided will serve as the basis for standardization for drug exploration from P. cakiloidea in Kurdistan. The study recommends further study on the anatomical features, de novo sequence and the chemical constituents of the species
