    • n valerianella A genus of gamopetalous plants, of the order Valerianeæ, chiefly distinguished from Valeriana by its toothed, lobed, awned, or horned, but never pappous calyx. There are about 55 species, annual herbs, dichotomously branched, with entire, dentate, or pinnatifid leaves, and cymes of white, paleblue, or pink flowers. The genus is chiefly confined to the Mediterranean region, extending into central Europe, but occurs in North America, and a few species are widely naturalized. Several species produce tender foliage, eaten as lettuce. V. olitoria, a species with pale-green leaves and small slate-colored flowers, widely diffused in Europe, North Africa, and Asia, formerly known as white pot-herb and lamb's-lettuce, and latterly as corn-salad, is now often cultivated under glass as an early salad under the name of fetticus. (See cut under dichotomy.) Twelve species, formerly classed under the related monotypic genus Fedia, are natives of the United States; four species of Oregon are peculiar in their spurred corollas. V. Woodsiana, with roundish, and V. chenopodifolia (Fedia Fagopyrum), with somewhat triangular fruit, extend from the south into New York.
