Description

Echinopsis aurea grows singly or in groups. The spherical to short cylindrical, dark green shoots reach heights of growth of 5 to 10 centimeters with a diameter of 4 to 6 centimeters. There are 14 to 15 sharp, distinct ridges separated by deep furrows. The brownish areoles on it are up to 1 centimeter apart. Brownish thorns or black thorns towards the base of the shoots emerge from them, which have yellowish tips. The usually four strong, often flattened central spines are 2 to 3 centimeters long. The eight to ten spread radial spines have a length of up to 1 centimeter.

The mostly shiny lemon yellow, rarely white or red flowers appear in groups on the side of the shoots and open during the day. They are up to 9 centimeters long and reach a diameter of 8 centimeters. The egg-shaped fruits are semi-dry and tear open.
