description
Austrocylindropuntia lagopus grows in very dense, large cushions with a diameter of up to 1 meter and a height of 60 centimeters. The humped and densely hairy shoot sections are short, cylindrical and up to 25 centimeters and more long. Occasionally they are shorter and more spherical. Very fine hairs up to 2 centimeters long arise from the areoles on them and are arranged in only one row. The white, slightly sloping glochids are only sparsely available and 1 to 1.5 centimeters in length. The up to 7 millimeters long leaf rudiments are hidden between the hair. The single yellow thorn is 2 to 2.5 inches long.
The golden yellow flowers are 2 to 3 inches long. The pericarpel is hairy towards the tip. The egg-shaped, thin-walled fruits are light yellow-green before ripening and then turn light pink.
Distribution, systematics and endangerment
Austrocylindropuntia lagopus is widespread in the highlands of the Peruvian region of Puno and Bolivia in the La Paz department at altitudes of about 4100 to 4700 meters.

Friedrich Ritter placed the species in the genus Austrocylindropuntia in 1981 , but did not give a direct page number on the description of the basionyma . In 2003 Ivor Crook , John Arnold and Martin Lowry validated Ritter's species names. Further nomenclature synonyms are Tephrocactus lagopus (K.Schum.) Backeb. (1936), Tephrocactus floccosus var. Lagopus (K.Schum.) F.Ritter (1958, nom. Inval. ICBN -Article 33.3), Andinopuntia lagopus (K.Schum.) Guiggi (2011) and Punotia lagopus (K.Schum .) DRHunt (2011).
