Matucana is a genus of cacti (family Cactaceae), containing approximately 20 species of mostly globular plants.[1] The genus is only known from Peru,[2] mostly along the Marañón River.

The first species was discovered near the town of Matucana and described as Echinocactus haynii by Otto in 1849. Matucana was erected by Britton & Rose in 1922.[2] The genus Eomatucana F.Ritter has been brought into synonymy with this genus.

Some species are endangered due to collection for the specialist market.

Description[edit]

Low, globose or shortly cylindrical bodies, either solitary or clustering. The flowers are subapical, usually more or less zygomorphic, diurnal, in various colours, but mainly red, yellow or pink.[3] However, a few species, notably M. oreodoxa and M. madisoniorum have actinomorphic flowers and were placed in a separate genus - Eomatucana - by F. Ritter. They are reported to flower easily at a young age.[4]

Cultivation[edit]

All members of the genus cannot tolerate too much moisture and must be watered only during their growing season and when the substrate is dry.[2] They must also be kept warm through the winter or risk losing their roots.[2] Members of Matucana grow quickly and may be grown from seed.[2]
