Water Bent plants

Native to the Mediterranean region.
Perennial grass with stolons (above-ground, trailing stems that root at their nodes). Erect stems to 100 cm high with hairless but rather rough, flat leaves to 15 cm long and 5 mm wide. Flower-heads are rather dense panicles to 12 cm long and 4 cm wide with a somewhat lobed appearance due to clustering of the spikelets towards the base of the branches. Spikelets are single flowered, each floret about 1 mm long, without hairs or awns.
Occasional across southern Victoria, on damp to wet sites, including roadside drains and irrigation ditches.
This species has always been difficult to place taxonomically as it has the general appearance of a Bent Grass (Agrostis) but the seed dispersal of a Beard-grass (Polypogon). Like Annual Beard-grass (Polypogon monspeliensis), the spikelets of Water-bent fall as a whole when mature, whereas the flower-heads of the Bent Grasses discard the florets only, leaving the glumes behind. Water Bent is most similar to Creeping Bent (Agrostis stolonifera) which differs in having a more open flower-head and slightly larger florets.
