Echinopsis pampana, synonyms including Lobivia pampana, is a species of Echinopsis found in Peru. [3] [4]
Echinopsis pampana usually grows singly and rarely sprouts. The spherical, blue-green to gray-green shoots reach a diameter of 10 centimeters and a height of up to 7.5 centimeters. They have a large taproot. There are 18 to 30 wide, sharp-edged, wavy ribs at its base, which are arranged in a spiral and have humps with obliquely offset cusps. The areoles on them are 1 to 2 centimeters apart. The needle-like to elastic thorns arising from them are yellowish pink to brown to blackish. The one or two upwardly curved central spines are up to 7 centimeters long. The nine to ten slightly curved marginal spines are 1 centimeter long.
The short, funnel-shaped flowers are open during the day. They are pink-beige to orange-red to yellow in color. The flowers are 3 to 5 centimeters (rarely up to 7 centimeters) long and have the same diameter. The egg-shaped to spherical fruits are juicy and reach a diameter of 2 centimeters. [5]
The species was first described by Nathaniel Lord Britton and Joseph Nelson Rose in 1922 as Lobivia pampana. [3] [6] The specific epithet pampana refers to the occurrence of the species in the Peruvian Pampa de Arrieros.[ citation needed ] In 1991, David R. Hunt transferred the species to Echinopsis, the placement accepted by Plants of the World Online as of November 2025 [update] . [3]
Echinopsis pampana is widespread in the Peruvian regions of Arequipa and Moquegua at altitudes of 3500 to 4100 meters.[ citation needed ]
