This annual grass is commonly 50-80 cm tall. The leaf blades have dark stem-clasping bases and a membranous tongue (ligule) between the blade and sheath. The purplish green inflorescence is fairly loose with large drooping spikelets. Each spikelet is 1-3 cm long with 3 florets, but only the upper one is fertile.
Fleabanes are annual herbs with a basal rosette of entire or toothed leaves and an erect, often greyish, leafy flowering stem. The small flower heads are cream to white and do not have the radiating petal-like florets seen in many daisies. Instead there are several slender tubular florets. Tiny fruits are topped by a ring of bristles.
