Abstract
A systematic study for eleven tribes of Gramineae surveyed 34 characters including fruit morphology, fruit anatomy and palynology. The results were conducted to some numerical analysis aspects. On the basis of UPGMA (Unpaired Group Method of Average) clustering and PCA (Principal component analysis), the results show congruence between the UPGMA clustering and PCA method, in suggesting two major clads/groups and five subclads.
