Echinocereus russanthus is a species of cactus native to Texas and Mexico.^[2]

Description[edit]

Echinocereus russanthus typically grows solitary or branches from the base. Its upright, cylindrical stems are 7.5 to 25 cm long and 5 to 7.5 cm 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 long, and 30 to 45 reddish to brownish radial spines, up to 1.8 cm 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 long and wide. The green, spherical fruits are heavily thorny.^[3]^[4]

Distribution[edit]

Echinocereus russanthus is native to the Big Bend region of southern Texas, USA, and the neighboring Mexican state of Chihuahua.

Taxonomy[edit]

First described by Del Weniger in 1969, the specific epithet "russanthus" comes from the Latin "russus" (reddish) and the Greek "anthos" (flower), referring to the flower's color.^[5]
