False Brome, Slender False Brome or Wood False Brome, (Brachypodium sylvaticum), is a perennial grass native to Europe, Asia and north Africa.
A tall tufted perennial bunchgrass growing up to about a 0.9 m high, it is most commonly found in forests and woodlands,(preferring the shaded canopy), but may grow in open areas. It prefers well drained neutral and calcerous soils, and avoids wet conditions.
It has drooping narrow long spikelets of flowers on very short pedicels and drooping leaves. Its awns are straight and 6 to 18 mm long, projecting out of the end of the spikelets. The flower head is 6 to 20cm long, the plant flowering in July and August
The leaf blade of the plant is dark green, or bright-yellow green, flat and up to 12 mm wide with a fringe of hairs surrounding the edge of the leaf. The leaves do not have auricles. The leaf blade is joined to the hollow culm by the leaf sheath. This hairy sheath is open and surrounds the culm. The culm is pilose (long, soft, hairy), and typically has 4 to 5 nodes.
The ligules are blunt, 1 to 6 mm long.
Its seeds can be dispersed by wildlife and humans. The caterpillars of some Lepidoptera use it as a foodplant, e.g. the Chequered Skipper (Carterocephalus palaemon) and the Essex Skipper (Thymelicus lineola).
