About Echinocereus russanthus D.Weniger
Echinocereus russanthus D.Weniger typically grows either alone or branches from its base. It has upright, cylindrical stems that measure 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, and these stems are covered in thorns. This cactus has 10 to 18 distinctly tuberculated ribs. It produces 7 to 12 spreading central spines, which can be red, cream, or brownish and grow up to 3 cm (1.2 in) long. It also has 30 to 45 reddish to brownish radial spines that reach up to 1.8 cm (0.71 in) long. Its short, funnel-shaped flowers range from light to bright red, and often grow in clumps on the sides of stems; the flowers sometimes do not open fully. Each flower measures 2.5 to 3 cm (0.98 to 1.18 in) in both length and width. The fruits of Echinocereus russanthus are green and spherical, and they are heavily covered in thorns. This species is native to the Big Bend region of southern Texas in the United States, as well as the adjacent Mexican state of Chihuahua.
