Wood False-Brome is a species of no value agriculturally and is generally considered undesirable in grassland.
Tor Grass, Brachypodium pinnatum (Linn.) P. Beauv., differs from Brachypodium sylvaticum by having a shorter awn shorter than the lemma, glabrous sheaths and culms and a rhizomatous habit. Although it is reported from Pakistan (R.R. Stewart 8732 det. Swallen in Stewart, Ann. Cat. Vasc. Pl. W. Pak. 138) this is probably an error as the species is otherwise unknown east of Iran. The Stewart specimen in question, which incidentally is at Kew despite Stewart's statement in his catalogue, although having short-awned glabrous spikelets is tufted and has hairy sheaths and leaves; it is thus better regarded as a form of Brachypodium sylvaticum.

This species is the most widespread in the genus and is extremely polymorphic throughout its range. This has resulted in the description of many infraspecific variants. These are usually based on differences in pubescence of the vegetative parts and spikelets, but these characters are extremely plastic. The relative size of the spikelet parts is also variable and of doubtful taxonomic significance.
The name Brachypodium sylvaticum var. kelungense is based on specimens from Taiwan with mucronate glumes, but these are found throughout the range of the species. Spikelets with acute and mucronate glumes may even occur in the same raceme. The name B. sylvaticum var. gracile has been applied to small forms in China, but it is based on a type from Germany, and such specimens are probably only depauperate. Thus, while phenotypic variants may appear very different, the characters on which they are based occur in all combinations throughout the range of the species, making the recognition of infraspecific taxa very uncertain. No detailed comparison has ever been made between the European and E Asian populations.
In tropical SE Asia Brachypodium sylvaticum occurs only on mountains.

Brachypodium sylvaticum
provided by wikipedia EN
Brachypodium sylvaticum, commonly known as false-brome,[1] slender false brome[2] or wood false brome, is a perennial grass native to Europe, Asia and Africa. It has a broad native range stretching from North Africa to Eurasia.[3]
The bunchgrass 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.
Description
Brachypodium sylvaticum is a tall tufted perennial bunchgrass that grows up to about a 0.9 metres (3.0 ft) high.
The drooping 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.[4] The ligules are blunt, 1–6 millimetres (0.039–0.236 in) long.
The grass has drooping narrow long spikelets of flowers on very short pedicels. The flower head is 6–20 centimetres (2.4–7.9 in) long, the plant flowering in July and August. Its awns are straight and 6–18 millimetres (0.24–0.71 in) long, projecting out of the end of the spikelets.
Wildlife value
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).
Invasive species in North America
The grass is an introduced species in North America. Brachypodium sylvaticum is an invasive species colonizing new areas and outcompeting native plants. As this species has spread to the Pacific Northwest of the U.S. it has demonstrated a capability of dominating forest understories and open grasslands to the exclusion of all other flora found in those areas.
Recent observations suggest that populations at the leading edge of the expanding range undergo an establishment phase before they can contribute to the local invasion, perhaps because newly colonized populations are suffering from inbreeding depression.
- Oregon
Brachypodium sylvaticum is a newly invasive brome species in Oregon that is rapidly expanding in the Pacific Northwest. Although B. sylvaticum appears to be in the early phases of invasion in North America, it has become a noxious weed throughout the Willamette Valley area of Oregon since the late 1980s.[5] It is most likely that B. sylvaticum was first introduced to Oregon in range experiments when accessions from the native range were planted near Eugene and Corvallis in the Willamette Valley using seed obtained from the USDA Office of Foreign Seed and Plant Introduction anywhere between 70 and 80 years ago.[6]
