Lobivia tiegeliana, is a species of Lobivia found in Argentina and Bolivia.[1]
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.[2]
Lobivia tiegeliana is widespread in the Bolivian department of Tarija and the Argentine province of Salta at altitudes of 1900 to 3300 meters.
The first description by Wilhelm Wessner was published in 1974. The specific epithet tiegeliana honors the German cactus lover and mammalian specialist Ernst Tiegel (1879–1936). Nomenclature synonyms are Hymenorebutia tiegeliana (Wessner) F.Ritter (1980) and Echinopsis tiegeliana (Wessner) D.R.Hunt (1991).
