Common name: In Venezuela “cacto dato”, in Colombia: “cardón”, “cardón guajiro”, "yosú", "panameña", and “iguaraya” (fruit).

Phenology: flowers and fruits are produced over the year, but the peak of production lasts from November to April.

Habitat: S. griseus grows in tropical deciduous forest and xerophytic scrub alongside with Cereus spp. , Prosopis juliflora , Bulnesia arborea , Ceiba sp. and Haematoxylum sp. From sea level to 1200 meters above sea level.

Discussion: S. griseus is the sole species of the genus Stenocereus to occur in South America. This name was actually a homonym comprising a previously undescribed northern Mexico species ( S. huastecorum ) and a second one from northern South America, which shall conserve the name S. griseus by priority principle.

Distribution: Departments of Boyacá, Huila, La Guajira, Magdalena, and Santander in Colombia; States of Falcón, Lara, Mérida, Sucre, Táchira, Vargas, and Zulia in Venezuela, it is also found in Aruba, Bonaire, and Curaçao islands.
