Robert E. Preston & Margriet Wetherwax


Annual to perennial herb, generally glabrous. Stem: erect, simple or branched at base. Leaf: generally opposite or whorled (or distal alternate), sessile, linear to ovate, generally wider on non-flowering shoots, entire to dentate, pinnately veined. Inflorescence: spike or raceme, terminal; bracts reduced, alternate. Flower: sepals 5, free to near base, lobes ± equal; corolla 5-lobed, 2-lipped, lower lip >= upper, lower side of tube spurred at base, lower side of throat swollen, ± hairy, ± closing corolla below lips; stamens 4, in 2 pairs, included; stigma small, lobes 0 or 2, flat. Fruit: opening by slits into chambers near tip, ± spheric. Seed: many, flat and winged or pyramid-shaped and 0–3-ridged.
± 100 species: Europe, Asia, northern Africa; many cultivated. (Latin: flax, from flax-like leaves of some) [Sutton 1988 Revision tribe Antirrhineae. Oxford Univ Press] Corolla length includes spur. Linaria supina (L.) Chaz. mistakenly reported for California in TJM (1993). Linaria canadensis moved to Nuttallanthus.
