    Identification difficulty
    ID guidance

    The panicle is branched. Each spikelet contains only one floret usually completely enclosed by its glumes. The inflorescence branches close together after flowering, and have closely spaced spikelets which are not awned. It is in a different genus from Creeping Bent, with even more crowded spikelets that sometimes lead to the description that the panicle is lobed.
