In the center of the stele and between the bundles is conjunctive tissue. Highly magnified.—After Sachs the center, or the center of the stele may be occupied by a pith (fig. 53). The number of vascular strands constituting the stele is various, being as few as four or as many as forty. The ordinary number, however, is from eight to twenty. (See fig- 53-) 76. 3. The cortex generally consists of large thin-walled cells which have become partially separated from one another, leaving larger or smaller intercellular spaces (fig. 53)..
