Strombocactus disciformis is a rare species of cacti and the only species of the genus Strombocactus. The plant originates from Central and Northeast Mexico.

Description[]

Strombocactus is a monotypic genus with a strong turnip-like root, a small, depressed, 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.[2]

Taxonomy[]

The species has several forms and subspecies:

  • Strombocactus disciformis f. cristata
  • Strombocactus disciformis ssp. esperanzae

Conservation status[]

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". The species is listed in Appendix 1 of the Convention on International Trade in Endangered Species meaning commercial international trade is prohibited and non-commercial international trade is regulated.[1]
