[AS.] A plant about two or three feet in height, with small pointed leaves and blue flowers. The stems are hollow, and covered with fibrous material. The flowers grow in clusters at the top of the stalks, and are succeeded by round seed-vessels the size of a pea. Each seed vessel contains ten flat seeds of a brown color. It thrives in a rich, moist soil. The leaves drop off when the plants are ripe, and the stems turn yellow. The stalks are pulled up and tied in bundles to dry. They are then steeped in water until softened, so that the fibres of the outside covering or bark can be separated. The fibre . of flax is spun and woven by machinery into linen, and then bleached by chloride of lime. Flax is grown in Europe and the United States, where it was introduced from England in 1629. Linen, lawn, and damask cloth are woven from flax-thread, and linseed oil is made from its seeds.
