Creeping Bent

Can be mistaken for

Red Fescue, which has a very short ligule.

Characteristics

Early stages
The vernation is convolute. The leaves are long, slender and with distinct ribs. No dentation. The ligule is long, up to approx. 5 mm.

Mature plant
Creeping Bent is a low-growing grass with 20-60 cm long, ascending to erect stems. The very small, one-flowered and awnless spikelets (approx. 1.5-3.5 mm long) are grouped in a panicle. The panicle is open during flowering, but closed after flowering has ceased. The species forms above-ground, rooting stems.

Seed
Elliptical to spindle-shaped without rachilla in the ventral furrow. No awn, but a short awn may occur. Domed to keeled bract with cellophane-like, often frayed tuft. The basal edge is encircled by fine bristles. Shelled seeds are common. Thousand grain weight approx. 0.1 g.

Biology

Propagation and dispersal
Through seeds and above-ground bolters.

Habit
Perennial.

Importance

The species is often found in permanent meadows on wet soil throughout Denmark. It is sometimes also found locally in annual crops. Creeping Bent has no appreciable significance as a weed.
