Even grasses make shade leaves. However, this Costa Rican grass (Olyra latifolia, Poaceae) from tropical dry forest lives only in dry forest understory and it always has a few large leaves (it lacks the ability to make thin grasssy leaves when put in the sun). It looks like some dicotyledonous angiosperm. Here it is bathed in a passing sunfleck, but normally it lives in the full shade (and does very well there, so this moment in the sun is probably pure Hell). Compare these leaves with those of a sun-loving grass in image DHJanzen100347.jpg above.
