Contents

Elsewhere this plant is commonly considered a weed.

Description

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. [4]
