Cleome brachycarpa Vahl. Figs. 13, 14, 19, 20, 21. Herbaceous. Front cavity of stomata on a level with the surface. Guard-cells a little above the plane of the surrounding cells. Mesophyll isobilateral. Some of the palisade cells with tanniniferous contents. Middle tissue of the mesophyll formed of large colourless parenchymatous cells. Veins provided with colourless sheaths. Glandular hairs multicellular and capitate. Outer walls of the epidermal cells of the axis granulated. Axis ribbed. Pericycle formed of large thin groups of stone-cells. Assimilatory tissue in the axis consisting of chlorenchyma. Wood composite. Soft bast forming a continuous ring. Pith formed of thin-walled cells.

Cleome viscosa L. Figs. 15, 16, 28. Herbaceous. Epidermis of the leaf formed of thin-walled cells. Guard-cells elevated a little above the plane of the surrounding cells. Front cavity of the stomata in a level with the surface. Mesophyll formed of palisade tissue on the adaxial side and of arm-palisade tissue on the abaxial side. Internal glands absent. Glandular hairs multicellular and capitate. Veins not provided with sheaths. Stone-cell groups of the pericycle triangular. Assimilatory tissue of the axis formed of chlorenchyma. Wood composite. Soft bast forming groups. Pith formed of thin-walled cells.

Gynandropsis pentaphylla DC. Figs. 22, 23, 24, 25, 26, 29. Herbaceous. Guard-cells a little elevated above the plane of the surrounding cells. Mesophyll formed of palisade tissue on the adaxial side and of spongy tissue on the abaxial side. Internal glands absent,
