The inner parts thus form a ring of wood and the outer parts form the inner bark or bast. A new ring of wood or bast is formed on stems of di- cotyledons each year, and the age of a cut stem is easily determined. When cross-sections of monocotyledonous and di- cotyledonous bundles are examined under the mi- croscope, it is readily seen.
