About Echinopsis lageniformis (C.F.Först.) H.Friedrich & G.D.Rowley
Echinopsis lageniformis ranges in color from light greenish to bluish. It grows in a shrubby to tree-shaped form, is somewhat branching, and typically has four to eight ribs. Mature plants reach heights of 2 to 5 metres (6.6 to 16.4 ft), with stems growing up to 15 to 20 centimetres (5.9 to 7.9 in) in diameter. The areoles on the stems are large and spaced 1.5 to 3 cm (0.59 to 1.18 in) apart. Two to six unequal spines emerge from each areole; these spines vary in color from honey-coloured to brown, and can reach lengths of 0.1 to 7 cm. On fully grown plants, spines are evenly spaced on the ribs at intervals of 2.5 to 3 cm. This species produces long, funnel-shaped white fragrant flowers that are 15 to 18 cm (5.9 to 7.1 in) long, open at night, and measure 16 to 20 cm (6.3 to 7.9 in) across. The fruits are spherical, hairy, and 4 to 6 cm (1.6 to 2.4 in) long. It is native to the La Paz, Cochabamba, Tarija, and Chuquisaca departments of Bolivia, where it grows at altitudes between 1000 and 3300 meters. Native Bolivian populations sometimes call it achuma or wachuma, though these common names are also used for related hallucinogenic species such as Echinopsis pachanoi. Echinopsis lageniformis is not the dominant species in areas where it occurs, except in the region around La Paz, Bolivia.
