description

Echinopsis arboricola grows shrubby, is initially upright and later becomes pendulous. The slender cylindrical, dark green shoots are up to 120 centimeters and more long. They have a diameter of 2.5 to 4 centimeters and form aerial roots . There are nine to eleven laterally compressed ribs on which there are almost cube-shaped or almost conical cusps up to 3 millimeters high. The areoles on the tips of the cusps are woolly white. From them arise nine to 15 radiating, needle-like and piercing thorns . One of the yellowish to brownish thorns, 0.1 to 2.3 centimeters long, is longer than the others.

The bell-shaped, white flowers appear near the tip of the shoot and open at night. They are 12 to 13 centimeters long and 13 to 15 centimeters in diameter.
