Echinocereus brandegeei

Echinocereus brandegeei grows with multiple shoots, forming large, loose clumps up to 2 meters in diameter. The light green, cylindrical shoots vary in size, creeping at their base with upright tips. They can reach up to 100 cm (39 in) in length and 6 cm (2.4 in) in diameter. Each shoot has eight to ten sharply angular ribs and is densely covered with thorns ranging in color from white to black. The four central spines, arranged crosswise, are flattened, stiff, and sword-like, measuring 3 to 13 cm (1.2 to 5.1 in) long. The ten to 18 radial spines are rounded, stiff, and up to 2 cm (0.79 in) long.

The broadly funnel-shaped flowers are light purple-lavender to light pink with a bright red throat. They appear along the entire shoot, measuring 5.5 to 9.5 cm (2.2 to 3.7 in) in length and 4 to 8.3 cm (1.6 to 3.3 in) in diameter. The spherical fruits are red.^[3]
