Ligule is very short and truncate.

Inflorescence is a spike-like panicle, up to 45 cm long, consisting of irregularly and distantly placed spiciform racemes that up to 15 cm long with spikelets are in 2 rows. The 9-13 mm long spikelets are ovate-lance-shaped, very short stalk, with 1 bisexual floret, which is having lower glume with a size of 3.5-4.5 mm long and 5-veined. The upper glume is 5-6.5 mm long and 5-7-veined. The lemma is 6-7 mm long and 7-9-veined while the palea is 5-6 mm long and strongly 2-veined.
