Loncomelos narbonense (L.) Raf. (syn.: Ornithogalum narbonense L.) (Medit., SW-As.) – An exceptional and ephemeral alien. Recorded once with certainty as a grain alien in the port of Antwerp in 2001 (Verloove 2006). A single plant, recorded between cobble stones in the city of Antwerp in 2011, probably also belongs to this species.
