This layer consistsof more or less sclerenchymatized cells with wavy outline. The radialwalls are, in some parts, moderately thickened, in others so thick thatthere is but a narrow lumen. All the walls are porous. 2. Spongy Parenchyma (hy). One or more layers of colorless cells,usually with numerous circular intercellular spaces, form a hypodermal
