Lobivia tiegeliana

Lobivia tiegeliana, is a species of Lobivia found in Argentina and Bolivia.

Description
Lobivia 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 are up to 1.5 centimeters apart. Reddish to horn-colored, prickly thorns emerge from them and turn gray with age. The up to three central spines are directed downwards and up to 5 centimeters long. The eight to ten marginal spines are 4 by 6 centimeters long.

The shiny violet-pink flowers, yellow in the flaviflora variety, appear near the top of the shoot and open during the day. They are up to 2.5 centimeters long and have a diameter of 4.3 centimeters. The spherical to egg-shaped, semi-dry fruits tear open.

Distribution
Lobivia tiegeliana is widespread in the Bolivian department of Tarija and the Argentine province of Salta at altitudes of 1900 to 3300 meters.
