'''''Linaria''''' is a genus of about 100 species of [[herb]]aceous [[Annual plant|annuals]] and [[perennial]]s that was traditionally placed in the [[foxglove]] family [[Scrophulariaceae]]. Due to new genetic research, it has now been placed in the vastly expanded family [[Plantaginaceae]]. The genus is native to temperate regions of [[Europe]], northern [[Africa]] and [[Asia]], with the highest species diversity in the [[Mediterranean region]].
The members of this genus are known in English as [[toadflax]], a name shared with several related genera. The scientific name means "resembling ''Linum''" ([[flax]]), which the foliage of some species superficially resembles.
Closely related genera include the ''[[Nuttallanthus]]'' (American toadflaxes, recently split from ''Linaria''), ''[[Antirrhinum]]'' (snapdragons) and ''[[Cymbalaria]]'' (Ivy-leaved toadflaxes).

'''Common Toadflax''' (''Linaria vulgaris'') is a [[Europe]]an species which is widely introduced elsewhere. The yellow and orange [[flower]]s are seen in many waste places. The species is also know
n in some areas as "[[butter-and-eggs]]".
'''Broomleaf Toadflax''' or '''Dalmatian Toadflax''' (''Linaria genistifolia'', syn. ''L. dalmatica'') is a native of southeast Europe that has become a weed in parts of [[North America]].
'''Purple Toadflax''' (''Linaria purpurea'') is native to the [[Mediterranean]] region, and is a popular [[garden]] plant, with erect stems up to 1 m tall when fully mature, with numerous dark purple or pink flowers.
'''Pale Toadflax''' (''Linaria repens'') from west Europe is similar to ''L. purpurea'', but has more pale colored flowers.
Since ''Linaria'' species are [[toxic]] to livestock, the plants are regarded as [[noxious weed]]s. However, toadflaxes are used as food plants by the [[larva]]e of some [[Lepidoptera]] species, including the [[Mouse Moth]], and the [[common buckeye]].
