Unusual greenish brown Mexican cactus with many pronounced, crowded, pointy tubercles that resemble leaves (thus the common name). White flowers appear at the apex in summer. Hefty tap root. 3-4 spines at the tip of the tubercles. Found exclusively in the Jaumave Valley, Tamauplias. Endangered and threatened by collecting. This monotypic genus has been associated with Ariocarpus and Strombocactus, but may be closer to Lophophora.
