Echinopsis lageniformis

The plant has a light greenish to bluish color grows shrubby to tree-shaped somewhat branching and usually has four to eight ribs. It can grow tall with stems of up to in diameter. The areoles on them are large and are apart. The two to six spines that emerge from them are unequal. Spines can range in coloration from honey-coloured to brown. These spines can grow up to 0.1–7 cm in length and in fully grown plants are spaced evenly on the ribs, 2.5 to 3 cm apart. The long, funnel-shaped, long white fragrant flowers open at night. They are long. The spherical fruits are hairy and are long. ==Distribution==

The plant comes from departments of La Paz, Cochabamba, Tarija and Chuquisaca Bolivia at altitudes of 1000 to 3300 meters. Among the native populations of Bolivia it is sometimes called achuma or wachuma, although these names are also applied to related species, such as Echinopsis pachanoi, which also have hallucinogenic effects. This does not occur in places where it is the dominant species, such as in the area of La Paz, Bolivia. ==Cultivars==

Several varieties of this species are highly prized by ornamental cactus collectors. These include a cristate variety, two variants of monstrose growth, and the more recently developed clone Trichocereus bridgesii monstrose crested that exhibits both monstrose and cristate growth. These all tend to be slower growing than the standard form of the species, but owing to their highly unusual shapes, they are sought after by cactus collectors. The monstrose form of Echinopsis lageniformis is known as the penis plant or penis cactus. Contrary to the typical columnar habit of the species, this cultivar displays short stem sections that branch avidly, forming a low spiny bush. The upper part of each stem segment is smooth and spineless, resembling a penis. The lower part is spiny and shows a tendency to form ribs. The plant is light green. The German name for this cultivar, Frauenglück, more euphemistic than its English equivalent, translates as "women's joy". Other highly valued cultivars are called Alko, Ben, Crown of Thorns, Experiment, Fahim`s Bridgesii #1, Fields Bridge, Foolsbreath, Rita, Jiimz Twin Spine, Nimbin, and Urban Tribes 2. ==Psychoactivity==

Like other species related to it, it has an ancient shamanic use in its place of origin. The plant contains a number of psychoactive alkaloids, in particular the well-studied chemical mescaline, typically at levels more consistent than Echinopsis pachanoi. The concentrations for specimens from various locations vary considerably and E. lageniformis may often contain higher mescaline content than E. pachanoi. However, a level of 0.56% mescaline content by dry weight was reported for some weaker E. lageniformis, while more than 2% for some extraordinary cultivars of E. pachanoi. Outside of its native habitat, it is one of the lesser known of the Trichocereus cacti for ornamental uses. This is not true in areas where it is the dominant species, for example, the La Paz area of Bolivia. As with related species, it seems to have long shamanic tradition of use throughout its native habitat. ==Gallery==
