The panicle itself is dense, open, linear, and is 4– long by wide. The nodes are whorled and are 3– long. Fertile spikelets are comprised out of 1 fertile floret which is diminished at the apex. They are also pediceled, the pedicels of which are 1– long with spikelerts themselves being oblong and long.[1]

Both the lower and upper glumes are oblong, keelless, membranous, have erosed apexes, and are 5-veined. Their size is different though; Lower glume is 2– long, while the upper one is 5– long.
