Antirrhinum litigiosum

Antirrhinum barrelieri is a species of perennial flowering plant in the genus Antirrhinum (common snapdragons) in the family Plantaginaceae. Native to northeastern Spain, the species is a subshrub that favors subtropical conditions. A. barrelieri produce stems of between 30 cm (12 in) and 75 cm (30 in) tall, on which narrow leaves and 8 to 20 pink or purplish tubular flowers grow. Flowering and fruiting generally occurs between March and September within the species's native range. In 1855, the botanist Alexandre Boreau was the first to describe the species with its current name, which Boreau gave the species in honor of the 17th-century biologist Jacques Barrelier. A. barrelieri has been reassigned or synonymized to other Antirrhinum, though genetic evidence has supported its placement as a discrete species. After 1896 descriptions by the botanist Carlos Pau y Español, the name A. barrelieri was applied to southern Iberian Antirrhinum; since a 2020 typification, these populations are now accepted as Antirrhinum controversum. Conversely, the name A. barrelieri has been restored to its original meaning in reference to plants native to northeastern Spain, replacing the Pau's synonym of Antirrhinum litigiosum.
