Strombocactus disciformis is a rare species of cacti and the only species of the genus Strombocactus. The plant originates from Central and Northeast Mexico.
Strombocactus is a monotypic genus with a strong turnip-like root, a small, sunken, roughly spherical stem covered with spirally arranged overlapping tubercles, each with a spine-bearing areole at its tip. Flowers come from new growth at the crown, and the cactus's small seeds are difficult to see with the naked eye.
The species has several forms and subspecies:
Both subspecies are classified as Vulnerable on the IUCN Red List, which states that it has a limited range and "is experiencing a decline in mature individuals due to illegal overcollection". Both sub-species are also contained in Appendix 1 of CITES species (Convention on International Trade in Endangered species) as at June 2013.
