This is a vintage botanical illustration featuring different types of lichen. The background is a creamy, off-white color. At the top, there's a large, irregularly shaped lichen with a greenish-gray hue. It has a slightly textured surface and a central, brownish-orange depression. To the right of it, there's a similar lichen, but with a more vibrant green color and a more defined central depression. Below these two larger lichens, there are two smaller illustrations. One depicts a bright green, branching lichen resembling a miniature coral. The other shows a dense, brownish-red, moss-like lichen. The illustration is detailed and appears to be hand-colored. There's a number '97' in the upper right corner. At the bottom, there's a text line that reads 'Plate 2. 1864. Published by J.S. Waring, London.'
