Kroenleinia grusonii (Hildm.) Lodé , also known in horticulture under its synonym name:; Echinocactus grusonii Hildm. has usually a single slowly growing globe-shaped stem that became elongated (barrel-shaped) in maturity, up to 90 cm (180 cm) in height and spread. It may offset with advanced age and a few multiples occur even at small sizes. Older specimens take on an oblong shape with age. They also tend to lean to the south or southwest so that the spines can better protect the body of the plant from the harsh desert sun. In fact, desert travellers can use the plant as a compass.
