Page 22 – Vascular boundary between cortex and stele
Fig. 19 . Vascular boundary between cortex and stele. Radial sections of the medial portion of the stem of a 6-months-old plant to show the cortical region (right) and the stelar region (left) separated by a cascular system, bundles of which are shown cut in cross section (at xx), and in longitudinal section (at l). Notice the tracheids in the latter. In B, a leaf trace is seen within the stelar region, cut in longitudinal section. Black specks in the ground tissue cells are starch grains. c, cortex; en, endodermis; lt, leaf trace; per, pericycle; tl, tracheids cut in longitudinal section; tx, tracheids cut in cross section. X50.
