Pachycereus (A.Berger) Britton & Rose

Pachycereus is a genus of 9–12 species of large cacti native to Mexico and just into southern Arizona, USA. They form large shrubs or small trees up to 5–15 m or more tall, with stout stems up to 1 m diameter.

Pachycereus comes from the ancient Greek "pakhus" meaning "thick" and the Latin "cereus" meaning "torch".
