The image is a detailed, black and white diagram of a cross-section of a wheat stem, likely a botanical illustration. It's presented as a circular shape, representing the stem's cross-section. The most prominent feature is the arrangement of vascular bundles, which appear as small, dark, oval-shaped clusters scattered around the periphery of the circle. These bundles are evenly spaced and define the outer ring of the stem section. Towards the center of the circle, there's a large area of ground tissue, composed of numerous small, polygonal cells (parenchyma cells). These cells are lighter in tone and create a honeycomb-like pattern. The central pith area is relatively uniform in texture. Around the outer edge of the circle, there's a thin, dark line representing the epidermis, the outer protective layer of the stem. Below the image, there's text indicating that it's 'Fig. 33. SECTION OF WHEAT-STEM.' and a magnification factor of 'x 15'. There's also a note '[to face page 110.]'. The overall impression is a scientific illustration intended to showcase the internal structure of a wheat stem at a magnified level.
