Several, see text Stenocereus (from Ancient Greek στενός (stenós) 'narrow' and Latin cereus 'candle') is a genus of columnar or tree-like cacti from the Baja California Peninsula and other parts of Mexico, Arizona in the United States, Colombia, Costa Rica, Guatemala, Venezuela and the West Indies.

[1] Stenocereus thurberi (the organ pipe cactus) is a well-known member of this genus and is widely distributed in Arizona and northern Mexico.

Those of Stenocereus gummosus, acidic and very refreshing, are highly favored by the Seris of northwestern Mexico[2] who call the cactus ziix is ccapxl[3] – "thing whose fruit is sour".

S. griseus (dagger cactus) fruits, locally known as iguaraya, are relished by the Wayuu people from the Guajira Peninsula of Colombia.

[4] Stenocereus are often used as ornamental plants in hot and arid regions, and as noted above, some species can double as a fruit crop.
