description
Echinopsis leucantha usually grows individually, but occasionally forms small groups. The spherical to short cylindrical, gray-green shoots reach heights of up to 35 centimeters (rarely up to 80 centimeters) with a diameter of 12 centimeters. There are twelve to 14 blunt ribs that are slightly notched. The elongated areoles located on them are yellowish white and 1 to 1.5 centimeters apart. The single thick, brown central spine is curved upwards and 5 to 10 centimeters long. The eight to ten yellowish brown radial spines are curved and somewhat twisted. They have a length of up to 2.5 centimeters.
The long funnel-shaped, white, occasionally slightly pinkish tinged flowers appear on the upper parts of the shoot and open at night. They are up to eight inches long. The spherical to elongated, fleshy fruits are greenish red to deep red.
