Plants within this genus may be identified by the distinctive structure of their fruits, which are marked by vertical splits that release their seeds upon maturity. The overall body shape, spination, offset production, and preferred habitat exhibit considerable variability, mirroring the diverse nature of the flowers within the genus. Species of Matucana have low, globose or shortly cylindrical bodies, either solitary or clustering. The flowers are subapical, usually more or less zygomorphic, diurnal, of various colours, but usually red, yellow or pink.[4] However, a few species, notably M. oreodoxa, have actinomorphic flowers and were placed in a separate genus - Eomatucana - by F. Ritter. They are reported to flower at a young age.[5][6]
The first species was discovered near the town of Matucana and described as Echinocactus haynii by Christoph Friedrich Otto in 1849. The genus Matucana was erected by Nathaniel Lord Britton and Joseph Nelson Rose in 1922 to differentiate it from the diverse Echinocactus genus.[3]
As of October 2023[update], the following species were accepted:[1][7]

All members of the genus cannot tolerate too much moisture so that it is recommended that they be watered only during their growing season and when the substrate is dry. They risk losing their roots if they are not kept warm through the winter. Members of Matucana grow quickly and may be grown from seed.[3]
