Description
Echinopsis tarijensis initially grows individually, later becoming a shrub with few side branches and reaching heights of growth of up to 5 m (16 ft). The strong, cylindrical, dark green shoots reach a diameter of up to 35 cm (14 in). There are 15 to 21 ribs. The large, clear areoles located on them are covered with gray felt and are close together. Light brown to whitish, unequal spines emerges from them. The stiff, stinging spines are slightly curved and thickened at their base. They have a length of 1 to 8 cm (0.4 to 3.1 in). One to four central spines and 50 or more radial spines are formed.[citation needed]
The funnel-shaped flowers are red to pink to creamy white. They appear near the top of the shoot. The flowers are up to 12 cm (5 in) long and have a diameter of 9 cm (3.5 in). The egg-shaped, green fruits are 3.5 to 5 cm (1.4 to 2.0 in) long and have a diameter of 2 to 3 cm (0.8 to 1.2 in).[citation needed]

Taxonomy
The first description as Cereus tarijensis by Friedrich Vaupel was published in 1916.[3] The specific epithet tarijensis refers to the occurrence of the species near Tarija in the Bolivian Department of Tarija. Spanish common names are "poco", "poco-poco", "achuma" and "cardón". The fruits are called "pasacana".[citation needed] In 1974, it was transferred to the genus Echinopsis. Boris O. Schlumpberger placed the species in the genus Soehrensia in 2012. As of February 2026[update], this placement was not accepted by Plants of the World Online, which retained it in Echinopsis.[2]
