description

Echinopsis mataranensis grows individually. The spherical, glauken shoots reach heights of 12 to 13 centimeters with diameters of 18 to 20 centimeters. There are eleven to 25 sharp-edged ribs that are notched and humped. The crooked areoles on them are light brown and are 2 to 3 centimeters apart. The eleven to thirteen spines arising from them cannot be divided into central and radial spines. They are somewhat comb-like, spread out or lie on the surface of the shoot. The 1 to 5 centimeters long, curved thorns are gray and swollen at their base.

The funnel-shaped, white flowers appear on the side of the shoots and open at night. They are 16 to 18 inches long and up to 8 inches in diameter. Their pericarpels and the flower tube are covered with tufts of black hair .
