Equally to the rest of the members of this family, each leaf contains a sheath that surrounds the petiole and protects the meristem or growing area and the the blade, that presents parallel nerves.

Flores in spikes. Each spike consisting of a main axis or rachis from whom the spikelets laterally spring. Spikelets consist of a main axis bearing some filaments finished by the glumes that contain the flowers until they begin to mature. Besides the glumes, the flowers are protected by other two bracts: the interior, called palea and the external one, called lemma. This last one finishes with a enlongated filament that confers the spike their feathery aspect.

Not very showy flowers without petals neither sepals. Female flowers with a single ovary from which two styles springing out, ending in two sticky feathery stigmas each one. Male flowers with three stamens golden, green or violet.
