Endothecium:Characteristic The fibrous bands.Arise chiefly along the inner tangential walls.Extend outward and upwards terminating near the outer tangential wall. In Trochodendron aralioides,the fibrous thickenings appear to continue along the outer tangential walls as well resulting in complete annular or ring-like bands. 24

● Endothecium o The endothecial thickenings are made up of a-cellulose,small amount of pectin and lignin as well. o The endothecium brings about the dehiscence of anthers. 25
