- For the bird genus, see Passerina (as originally described by Bartram in 1791) or Carduelis (as invalidly established by Bechstein in 1802).
Linaria is a genus of 150 species of herbaceous annuals and perennials and the largest genus in the Antirrhineae tribe of the Plantaginaceae family.
Contents
Taxonomy[edit]
Linaria was traditionally placed in the figwort family Scrophulariaceae. Phylogenetic analysis has now placed it in the vastly expanded family Plantaginaceae.
Closely related genera include the Nuttallanthus (American toadflaxes, recently split from Linaria), Antirrhinum (snapdragons) and Cymbalaria (Ivy-leaved toadflaxes).
Species[edit]
Some of the more familiar Linaria include:
- Common toadflax or butter-and-eggs (Linaria vulgaris), a European species which is widely introduced elsewhere and grows as a common weed in some areas.
- Broomleaf toadflax or Dalmatian toadflax (Linaria genistifolia, syn. L. dalmatica), a native of southeast Europe that has become a weed in parts of North America.[1]
- Purple toadflax (Linaria purpurea), a species native to the Mediterranean region grown as a garden plant for its dark purple or pink flowers.
- Pale toadflax (Linaria repens), a species from western Europe similar to L. purpurea, but with paler flowers.
Etymology[edit]
The members of this genus are known in English as toadflax, a name shared with several related genera. The scientific name Linaria means "resembling Linum" (flax), which the foliage of some species superficially resembles.
Distribution and habitat[edit]
The genus is native to temperate regions of Europe, northern Africa and Asia, with the highest species diversity in the Mediterranean region.
Ecology[edit]
Some Linaria are regarded as noxious weeds. They are likely toxic to livestock, but ruminants generally avoid them.[2]
Uses[edit]
Toadflaxes are used as food plants by the larvae of some Lepidoptera species, including the Mouse Moth (Amphipyra tragopoginis) and the Common Buckeye (Junonia coenia). L. vulgaris has been used as a medicinal herb for the treatment of many illnesses and conditions, including cancer, hepatitis, hemorrhoids, scrofula, and scurvy. It has been used as an astringent, an emollient, and a laxative.[3]
