The plant is perennial and caespitose with 20-57 centimetres (7.9-22.4 in) long culms and smooth internodes. The ligule is going around the eciliate membrane. Leaf sheaths have an erect and obtuse auricle and are open with hairy surface while the leaf-blades are conduplicate, elliptic, glaucous, filiform, pruinose and are 0.5-1.1 millimetres (0.020-0.043 in) broad. The panicle is open, inflorescenced, and 9-12 centimetres (3.5-4.7 in) long with smooth main branches which are spreading. Spikelets are oblong, solitary, 6.2-7.5 millimetres (0.24-0.30 in) long, and carry fertile ones that are pedicelled. Fertile florets are diminished at the apex and have 3-8 fertile florets. The glumes are chartaceous, lanceolate and keelless while the apexes and size are different. The upper glume is 0.8-0.9 millimetres (0.031-0.035 in) long and have an acuminate apex while the lower glume apex is acute with absent lateral veins. Fertile lemma is 3.4-4.9 millimetres (0.13-0.19 in) long and is also glaucous, ovate, and is as chartaceous and keelless as the glumes. The main lemma is carrying one awn that is 0.5-1 millimetre (0.020-0.039 in) long and also have an acuminated apex.
