This is a vintage botanical illustration of a cactus, specifically a Mammillaria dolichocephala. The cactus is a rounded, globular shape, densely covered in numerous spines. The spines are thin and dark, giving the cactus a textured appearance. At the top of the cactus, there are several small, pink flowers blooming. The flowers have a delicate, petal-like structure. The cactus is depicted in a simple, neutral-toned pot. The illustration is rendered in a detailed, realistic style, with careful attention to the texture of the spines and the delicate structure of the flowers. The background is a soft, off-white color. Below the illustration, there is text in French identifying the plant as 'Mammillaire à Longues Epines' and 'Mammillaria Dolichocephala'.
