Description

Polypogon monspeliensis is an annual tufted grass, usually 20–80 cm tall, with erect or ascending culms arising from a fibrous root system. Stems are slender, cylindrical, smooth, and often branched from the base. Leaves are linear, flat, and soft, usually 5–25 cm long and 2–8 mm wide. Leaf blades are green, sometimes slightly rough on the margins. Leaf sheaths are smooth, and the ligule is membranous and prominent. The inflorescence is a dense cylindrical or spike-like panicle, usually 3–15 cm long, resembling a soft brush or rabbit tail. Spikelets are densely crowded along short branches. Each spikelet contains a single floret, and the lemma bears fine awns that give the inflorescence a hairy appearance. The fruit is a small caryopsis enclosed by persistent floral bracts.
