Description

A sturdy grass with dense but interrupted panicles of pale green to purplish flowers, with one floret per spikelet, the glumes and lemma without awns. The branches are very crowded. Trailing stems, 60 to100 cm, rooting at nodes. Ligule is oblong with a lobed membrane.

Creeping Bent, Agrostis stolonifera

Identification difficulty
ID checklist (your specimen should have all of these features)

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.
