Berlandier's Hedgehog Cactus

Echinocereus berlandieri grows with many shoots and forms groups up to 1 meter in diameter. The dark green to somewhat purple-green, cylindrical shoots that taper towards their base are prostrate or have upright tips. They are 5 to 60 cm (2.0 to 23.6 in) long and reach a diameter of 1.5 to 3 cm (0.59 to 1.18 in). There are five to seven ribs with barely any hint of humps. The one to three strong, outward-facing, yellowish to dark brown central spines are 2.5 to 5 cm (0.98 to 1.97 in) long. The six to nine whitish marginal spines are 1 to 2.5 cm (0.39 to 0.98 in) long. The broadly funnel-shaped flowers are pink to reddish purple and appear below the tips of the shoots. They are 7 to 8 cm (2.8 to 3.1 in) long and reach a diameter of up to 7 cm (2.8 in). The egg-shaped, green fruits are 2 to 2.5 cm (0.79 to 0.98 in) long. The thorns on it fall off.

Echinocereus berlandieri is widespread in the United States in the south of Texas and in the neighboring Mexican states of Nuevo León and Tamaulipas at altitudes of up to 600 meters.
