Dactyloctenium Willd , Desmostachya Stapf , Dinebra Jacq , Diplachne P. Beauv. and Eragrostis P. Beauv.) has been comparative systematically and anatomically studied. One species of the four former genera and two species of the latter genus were included in the present research .
Also the study involving anatomical characters for the lemmas and pleas for the studied genera .
