Hojas numerosas, caulinares; vainas redondeadas, ciliadas, con tricomas auriculares conspicuos; lígula 0.2-0.4 mm; láminas 3-14 cm x 2-5 mm, en su mayoría dobladas, glabras en el envés, escabrosas y a veces esparcidamente papiloso-pelosas en el haz. Panícula 2-9 cm x 3-10 mm, densa, cilíndrica; eje oculto; ramas en su mayoría solitarias, erectas, densifloras hasta la base. Espiguillas 2-3.3 mm, grisáceas o pajizas, adpresas; gluma inferior 1.7-2.4 mm, 1-nervia, acuminada; gluma superior 2-3.1 mm, 1-nervia, acuminada; lema 1.9-2.5 mm; anteras 3, 0.8-1.6 mm.
