Pachycereeae
Buxb. 1958

Etymology: Tribe of plants that resemble Pachycereus
Place of Origin: Primarily in Mexico, though it also has some presence in neighboring countries.

Primarily columnar in form, many of them large and robust due to their high-strength woody structure. However, they also include small globular or even creeping species. They are generally not segmented but feature well-defined ribs. They possess a highly resilient epidermis and cuticle, adapted to both intense sun exposure and water loss, enabling them to survive in extremely arid environments. The flowers are large, nocturnal, funnel-shaped, and covered with scales, spines, or fibers depending on the species. The fruit is fleshy and typically edible. These plants produce a large quantity of seeds, usually small with a hard seed coat, which aids in their dispersal and survival in arid environments.
