Summary
The thick-walled lignified, pitted cells found in the stem and leaf ofAvicennia may be placed under the category of “Brachysclereids” or “stone-cells” of Tschrich (1885) and Foster (1949). These are transformed parenchyma cells in the stem, a hypodermal or mesophyll cell in the petiole and lamina of the leaf. They are formed by the “secondary sclerosis” of these parenchyma cells.
