Common names: Mediterranean barley; seaside barley
Hordeum marinum (Mediterranean barley) is a low-statured annual grass (family Poaceae) that is native to the Mediterranean and is commonly found in disturbed sites. It can outcompete other low-statured native plants and leaves behind a persistent thatch. Mediterranean barley occupies slightly wetter, more saline, and alkaline habitats than Hordeum murinum (hare barley). It can be distinguished from H. murinum by having generally shorter leaves with more hairy leaf sheathes, and shorter lemmas and awns on spikelets.Cal-IPC Rating: Moderate?
