Fibrous Tissue. — This is composed of elongated, thick-walled, and generally fusiform fibres (Fig. 16), whose walls are usually marked with simple or sometimes bor dered pits. These fibres in cross-section are rarely square or round, but most generally three- to many-sided. They are found in, or in connection with, the woody bundles of ferns and flowering plants, and give strength and hardness to their stems and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bessey, Charles E.
