Wide Fat Round Grass Leaf

[Don Schaeffer]

This grass attracted my interest because the leaf is fat and round. It seemed to have some girth and thickness. It would like the body-builder of grass. The cells are large and shapely. I tried to narrow down the name of the species but I'm just not able to. Lovely but humble plant though.
