Echinocereus russanthus is a species of cactus native to Texas and Mexico.[2]
Echinocereus russanthus typically grows solitary or branches from the base. Its upright, cylindrical stems are 7.5 to 25 cm (3.0 to 9.8 in) long and 5 to 7.5 cm (2.0 to 3.0 in) in diameter, covered by thorns. The plant has 10 to 18 ribs that are distinctly tuberculated. It features 7 to 12 spreading central spines that are red, cream, or brownish, up to 3 cm (1.2 in) long, and 30 to 45 reddish to brownish radial spines, up to 1.8 cm (0.71 in) long.
The short, funnel-shaped flowers are light to bright red and often appear in clumps on the sides of the shoots, sometimes not fully opening. The flowers are 2.5 to 3 cm (0.98 to 1.18 in) long and wide. The green, spherical fruits are heavily thorny.[3][4]
