Abstract
Xylem rays (wood rays) are sheets of parenchyma (sometimes sclerosed) extending radially inward from the cambium. In most woody plants, a few primary rays are extended by the cambium as secondary rays, while numerous other secondary rays are added by the cambium. In some herbs or woody herblike plants, many of the primary rays may be extended by the cambium with few modifications and only a small number of wood rays added by the cambium.
