FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets lanceolate; dorsally compressed; 12 mm long; falling entire; deciduous with accessory branch structures; readily shedding fertile florets.
GLUMES Glumes similar; exceeding apex of florets. Lower glume linear; 12 mm long; 1 length of upper glume; coriaceous; without keels; 3 -veined. Lower glume surface scabrous. Lower glume apex attenuate. Upper glume linear; 12 mm long; coriaceous; without keels; 3 -veined. Upper glume surface scabrous. Upper glume apex attenuate.
FLORETS Fertile lemma elliptic; 5–7 mm long; coriaceous; without keel; 5 -veined. Lemma surface scabrous; villous; hairy above. Lemma apex attenuate; awned; 1 -awned. Principal lemma awn 5–7 mm long overall; limb scabrous. Palea 2 -veined. Palea keels ciliate. Apical sterile florets 1 in number; barren; linear; 3 mm long.
FLOWER Ovary pubescent on apex.
