There are some commercial fibers produced by plants of the dicotyledonous kind. Manila hemp is from a species of banana, and sisal hemp, from an agave, one of the century plant group; these fibers are derived from the entire bundle, both xylem and phloem, and this origin probably accounts for their stiffness and hardness and their resistance to abrasion. inateflowers (in clusters called catkins) at B; pistil- late flowers, each with two stigmas, at Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability -
