Occasionally the rambler will find the Flax in cornfields and wastes, by oil-mills and in the neighbourhood of railway stations. Wherever it may be found it is an escape from cultivation. As a truly wild plant the "most used" flax is not known: in cultivation, as the parent of linen garments, it has been known from the infancy of the human race. To-day the exports of flax and linen from the United Kingdom are worth about &pound;5,500,000 per annum. It is therefore a plant that would be entitled to respectful consideration when we meet it, even if it had no grace or beauty to commend it to us. Common Flax is an annual plant, with erect slender stems about a foot and a half high. Its narrow lance-shaped leaves are arranged alternately and at a distance from each other. The flowers are large, and purplish-blue in colour. Five is the number dominating the structure of the flower: sepals, petals, stamens, glands, ovary (5 cells), styles all in fives. It flowers in June and July. There are three other species that are truly wild in Britain:&mdash;

III. Narrow-leaved Flax (L. angustifolium). Leaves alternate, as narrow as in the last species, but smaller and not so plentiful. Flowers smaller and paler, petals smaller in proportion to the calyx. Flowers May to September. Sandy and chalky pastures, not farther north than Lancashire.}}
