Origin: Introduced

selected vouchers: WTU

Notes: FNA24: "Lolium multiflorum, a European species, now grows in most of the Flora region. It is planted as a cover crop, as a temporary lawn grass, for roadside restoration, and for soil or forage enrichment; it often escapes from cultivation, becoming established in disturbed sites.

Lolium multiflorum and L. perenne are interfertile and intergrade. Lolium multiflorum differs from L. perenne in being a taller, shorter-lived perennial or annual with wider leaves that are rolled, rather than folded, in the bud. Hybrids between the two species are called Lolium ×hybridum Hausskn. Lolium multiflorum also hybridizes with L. rigidum; those hybrids are called Lolium ×hubbardii Jansen & Wacht. ex B.K. Simon."
