Gymnocalycium nidulans

It is a dwarf cactus with a globular body of an olive-green color. From the areoles, present on each tubercle of the rib, long and rigid gray-pink spines emerge, which, intertwining, form a kind of bird's nest, hence the name 'G. nidulans'. The flowers bloom at the apex of the stem and have a beautiful pink-white color.
