Linaria hirta (L.) Moench (Iberian Peninsula) – A very rare and ephemeral alien. Recorded in 1999 and 2000 as grain alien on a disused railway yard in the Ghent port area, along with numerous additional interesting grain aliens (Verloove 2003).
This species somehow looks like Linaria supina but has wider leaves, seeds that are not winged and larger corollas (Sáez & Bernal 2009).
