Hordeum bulbosum is a perennial, outbreeding relative of the cultivated barley, with a swollen, bulb-like culm base. It is widespread in the Mediterranean region and SW Asia, with diploids in the west and tetraploids in the east, the border following more or less the Pindos mountains. Fairly common at low and moderate altitudes, it may be gregarious along roads.

This species comprises diploids in the W & C Mediterranean area to W Greece and tetraploids from C Greece eastwards to Afghanistan, the border following the Pindos mountains. However, the two cytotypes cannot be distinguished morphologically and a taxonomic subdivision of the species is not recommended (Jørgensen 1982).
