This is a vintage botanical illustration on a pale yellow background. It features a detailed depiction of a plant, likely a type of gall or growth on a tree. At the top is a large, irregular, bulbous structure with a crystalline, geometric core in shades of blue and white. This core is surrounded by a dense, fibrous, and textured outer layer, rendered with fine, swirling lines. The top of the structure is covered in small, green, clustered growths, resembling tiny fruits or seeds. Below this main structure are four circular depictions of the plant's fruit or seed. Two of these are larger and show a cross-section revealing a textured interior. The other two are smaller, one showing a full view and the other a smaller cross-section. At the very bottom is a depiction of a stem with small, green, clustered growths similar to those on the main structure. The illustration is rendered in a detailed, scientific style, with fine lines and shading. The overall impression is one of a meticulous botanical study. At the bottom of the image is text that reads: “Oct. 1. 1811. Published by W. Curry, London.”
