Frailea buenekeri

Among the other specimens of its family, it turns out to be one of the smallest. In fact, it has a small globose or slightly elongated stem that usually does not exceed 2 cm in diameter, of a reddish brown color. It is covered with dense oval areoles, under which small “purple moons” can be seen. This greater or lesser evident feature makes it a highly sought-after plant. Its tiny spines are combed and white in color. In the flowering season, it produces huge flowers of a beautiful bright yellow color at the apex.
