Cross-Section Through an Internodium of a
Xanthium strumarium (Burweed) Shoot

Below the epidermis is a ring of small collenchyma cells (K). The largest part of the shoot is made up from large parenchyma cells with thin walls (P). The vascular bundles (L) are arranged in a peripherous ring (p Phloem with small cells, x Xylem with large lumina). Fascicular (fK) and interfascicular (iK) cambium are present. The central cylinder (Z) is enclosed by the cambium (K). (J. E. SLIWINSKI, F. B. SALISBURY, 1984).
