Echinocereus barthelowianus is a species of cactus native to Mexico.[2]
Echinocereus barthelowianus often forms clusters up to 80 cm (31 in) in diameter.[3] Its cylindrical, upright shoots grow up to 30 cm (12 in) long and 3.5 to 5 cm (1.4 to 2.0 in) in diameter, mostly covered by dense thorns. It has eight to ten slightly tuberous ribs with large areoles.[3] The thorns, pink to red when young, darken to black with age.[3] The five to nine strong, straight central spines can reach up to 7 cm (2.8 in) long, and the 18 marginal spines are 1 to 2 cm (0.39 to 0.79 in) long.[3]
The broad, funnel-shaped flowers are lavender and appear from the shoot tips to the base. They grow up to 5 cm (2.0 in) long and 4 to 6 cm (1.6 to 2.4 in) in diameter.[3]
