The flax-fiber, from the inner bark of the flax- '^' ■ , . stem, 5, fig. 31, is a tube of thicker walls and smaller bore than the cotton-fiber, and hence is more durable than cot- ton. It is very flexible, and even when crushed or bent short, "retains much of its original tenacity. Hemp-fiber closely resemble...s flax-fiber in appearance. . Xhickening of tlie Cell-lMiein'braiie. — The growth of the cell, which, when young, always has a very delicate outer membrane, often results in the thickening of its walls by the Interior deposition of cellu- lose and lignin. This thickening may take place regularly and uniform- ly, or interruptedly. The flax-fiber, 6, fig. 31, is an example of nearly uniform thickening. The irregular deposition of cellulose is shown in fig. 33, which exhibits a section from the seeds (cotyledons) of the com- mon nasturtium, ( Tropoeolum r/iajus).
