The genus Cleome L. was analysed numerically to find out the relationship of 11 species from Pakistan. Hierarchical clustering was performed by using Euclidean distance index and 214 characters from gross morphology, phenolic compounds, micromorphology of leaf, pollen, seeds and seed coat elements were taken into consideration. Results obtained by numerical data indicated the occurrence of two distinct groups. The group I comprised of 7 species viz., C. karachiensis, C. scaposa, C. brachycarpa, C. fimbriata, C. rupicola, C. viscosa and C. oxypetala and group II was represented by C. ariana, C. dolichostyla, C. pakistanica and C. spinosa. It was concluded that the group of species indicated the close affinity among them except that of the two morphologically allied species viz., C. karachiensis and C. viscosa which fell in separate groups. Which indicate that synthetic approach does not necessarily correlate with subjective findings.
