caption: The image shows a drawing of three fern leaves on a white background. The leaves are of a marginal wood fern, with each leaf having a unique shape and texture. The veins of the leaves are visible, and the veins are a deep green color. The fronds are arranged in a triangular formation, with the largest leaf in the center and two smaller leaves on either side. The background is a bright white, providing a stark contrast to the vibrant green of the fern.
