Common in damp grassy places

Flower-spike c 5 mm wide (excluding anthers).  Spikelets c 3 mm long excluding awn.  Anthers c 2 mm long.

ID: Told from Meadow Foxtail, which can also root at lowest nodes, by spikelets being < 3.3 mm long rather than > 4 mm (excluding awn).  Ligule on Marsh is up to 5 mm; max 2.5 mm on Meadow.  Told from Timothy by flower-spikes tapering at each end rather than abruptly rounding off, and by hairs on edges of spikelet ascending rather than horizontal.

Other features: Generally a small low grass, whose stems start off along the ground, rooting at nodes, then curve upwards.
