Plant tissue in which the primary cell walls are thickened, especially at the cell corners. Acts as a supporting tissue in growing shoots, leaves and petioles. Often arranged in cortical "ribs", as seen prominently in celery and rhubarb petioles. Lignin and secondary walls are absent; the cells are living and able to grow.
