Information about  Brachypodium distachyon from other sources

[Wikipedia] Europe, Africa, Asia native: Brachypodium distachyon, commonly called purple false brome[1] or stiff brome,[2] is a grass species native to southern Europe, northern Africa and southwestern Asia east to India. (contributed by Mary Ann Machi)

[Cal-IPC] Invasive: Brachypodium distachyon (annual false-brome, false-brome, purple false-brome) is a winter annual grass (family Poaceae) that is locally abundant in drier regions of California. Its native range is Eurasia with a primary distribution center in the Mediterranean. Annual false-brome has been introduced and become problematic across several other regions of the world. This grass can be distinguished from other invasive grasses by having a flattened and compact inflorescence, a relatively short stature, culms that may be angled, and nodes that are hairy. Leaves are greenish blue with stiffened hairs; plants feel rough to the touch. Brachypodium distachyon occurs primarily in dry, open, or disturbed sites and flowers later than most other annual grasses. It can outcompete native plants and leaves a persistent thatch that increases fuel load and impacts native seed germination. Cal-IPC Rating: Moderate (contributed by Mary Ann Machi)
