Discocactus is a genus of tropical cacti. Discocactus plants are endemic to southern Brazil, eastern Bolivia, and northern Paraguay. These species are in the risk of extinction in the wild.
==Description== The species of the genus Discocactus are depressed spherical to spherical and usually solitary plants, with mostly numerous, at the base somewhat broadened ribs and well-developed warts. The areoles are usually covered by strong thorns. At the apex of the adult plants, there is a wooly cephalium, white or shaded with yellow or grey. The terminal cephalium, up to 4 centimeters high, is slightly depressed. It consists of white, yellowish to grayish white wool and may have bristly spines.
