description
Echinopsis tiegeliana usually grows individually. The dwarf, depressed spherical to spherical, shiny green shoots reach a diameter of up to 6 centimeters. There are 17 to 20 sharp-edged and spirally arranged ribs , which are divided into cusps. The areoles on them are white and up to 1.5 centimeters apart. From them arise reddish to horn-colored, awlish thorns that turn gray with age. The up to three central spines are directed downwards and up to 5 centimeters long. The eight to ten radial spines have a length of 4 by 6 centimeters.
The shiny purple-pink flowers , yellow in the flaviflora variety , appear near the apex of the shoot and open during the day. They are up to 2.5 inches long and 4.3 inches in diameter. The spherical to egg-shaped, semi-dry fruits tear open.
