Echinopsis formosa is a species of the genus Echinopsis in the cactus family(Cactaceae). The specific epithet formosa is derived from the Latin word formosus for 'stately' and refers to the appearance of plants.
description
Echinopsis formosa initially grows individually, later occasionally branching out from the base and then forming groups. The spherical to cylindrical, light green to blue-green shoots reach heights of up to 1.5 meters with diameters of 25 to 50 centimeters. There are 27 to 50 rounded ribs that are clearly notched and tubercular. The dark areoles on them are up to 1 centimeter apart. From them arise needle-like, yellowish to reddish brown thorns . The two to nine central spines are 3 to 20 centimeters long. The nine to 15 radial spines are spread out, straight or slightly curved and have a length of up to 3 centimeters.
The broad, funnel-shaped, red to orange-red to yellow flowers appear near the apex of the shoots and are open during the day. They are 6 to 9 inches long and have the same diameter. The broad, spherical, green fruits are up to 3 centimeters long and 4 centimeters in diameter.

Echinopsis formosa is widespread in the Bolivian department of Tarija , in the Argentine provinces of Salta , Tucumán , Catamarca , La Rioja , San Juan and Mendoza as well as in the adjacent northeast of Chile in the high altitudes of the Andes of up to over 4000 meters.
