This annual, tufted grass has geniculately ascending
culms reaching 15 to 45 cm in length. The
leaf sheaths feature ciliate oral hairs and
falcate auricles, while the
ligule is a membranous structure without cilia. The
leaf blades, which are either flat or involute, grow between 5 to 10 cm long and 2 to 2.5 mm wide, with a smooth, hairless surface.
Flowers The plant produces a single, linear
raceme, measuring 5 to 8 cm long, with 12 to 16 fertile
spikelets arranged bilaterally along its length. The
rachis is fragile at the
nodes, with oblong
internodes that are about half the length of a fertile spikelet and detach along with the spikelet above
Spikelets The fertile spikelets are elliptic, laterally compressed, and range from 5.5 to 8.5 mm in length. Each consists of one or two fertile
florets, with diminished florets present at the tip. The spikelets detach as a whole, along with accessory branch structures. A rudimentary sterile spikelet is present at the base, numbering one per raceme. ==References==
