Description

Echinocereus acanthosetus grows solitary almost spherical to spherical, green to stems reach height of 3.9 to 6.2 mm (0.15 to 0.24 in) a diameter of 12.1 to 25.5 mm (0.48 to 1.00 in). There are eight to ten low and wide ribs. There are 5-9 radial spines that are 2 to 7 mm (0.079 to 0.276 in) long growing on elliptical areoles. The short, funnel-shaped flowers are magenta to cream white and appear near the tips or sides of the shoots. They are 31.6 to 48 mm (1.24 to 1.89 in) long and reach a diameter of 41.8 to 46.6 mm (1.65 to 1.83 in).
