Linaria

a genus of plants of the family Scrophulariaceae. They are perennial or, less frequently, annual grasses with numerous slender alternate or verticillate leaves. The flowers are bilabiate and gathered in racemose or spicate inflorescences. The fruit is a capsule. There are approximately 150 species, distributed in the northern hemisphere outside of tropical regions, primarily in the Mediterranean region. More than 60 species are found in the USSR, mainly in the Caucasus and Middle Asia. Common toadflax, or devil’s-flax (Linaria vulgaris), is a common weed that grows among crop plants; it also grows in sandy areas along roads and forest edges, in pine forests, and on slopes. Toadflaxes are nectar-bearing plants. Some species of Linaria, such as L. bipartita, are grown as ornamentals.

(2010) that Linaria alpina retains its viability in the soil for 5 years as estimated by artificial burial experiments, can be called into question because the soil environment may not enable adequate burial and subsequent avoidance of disturbance to maintain the conditions generated in their experiment.

En las areas mas favorables para la acumulacion de la nieve la vegetacion consiste en formaciones herbaceas y abiertas de especies quionofilas --como Sedum candollei, Digitalis thapsi, Paronychia poligonifolia, Criptogama crispa y Linaria saxatilis-- y plantas tolerantes a una larga duracion de la nieve --como Agrostis truncatula, Leucantemopsis pallida, Sedum brevifolium y Senecio pyrenaicus-- (Fernandez-Gonzalez 1991, Palacios y Garcia 1997).
