Echinopsis huascha, synonym Soehrensia huascha, is a species of Echinopsis in the family Cactaceae, found in north western Argentina. ^[2]

Description

The plants usually branch at the base and form low groups with heights of up to 1 m (3.3 ft). The cylindrical, fresh green, upright or creeping trunks with an erect shoot tip have 14 to 17 ribs and reach about 5 cm (2.0 in) in diameter. The areoles, from which the yellowish to brownish, needle-like spines arise, reach a diameter of up to 1 cm (0.39 in). The 1 to 3 central spines are slightly thicker than the radial spines and are 2 to 7 cm (0.79 to 2.76 in) long. The 9 to 11 radial spines are up to 1.5 in long.

The funnel-shaped to bell-shaped flowers that appear near the apex are very variable. They open during the day and are up to 10 cm (3.9 in) long and up to 7 cm (2.8 in) in diameter. The olive green, 4.5 cm (1.8 in) long flower cup is covered with 4 to 6 mm (0.16 to 0.24 in) long, brownish to black hair.

The spherical to egg-shaped fruits are yellowish green or reddish and reach a diameter of up to 3 cm (1.2 in). ^[5]

Taxonomy

The first description of the species was as Cereus huascha in 1893 by Frédéric Albert Constantin Weber. ^[6] The specific epithet huascha is derived from a local Argentine word meaning 'orphan'.^{[ citation needed ]} It was transferred to the genus Echinopsis in 1974. ^[2] Boris O. Schlumpberger placed the species in the genus Soehrensia in 2013. ^[7] As of February 2026 ^[update] , this placement was not accepted by Plants of the World Online, which retained it in Echinopsis. ^[2]

Subspecies

It has 2 accepted subspecies: ^[2]

• Echinopsis huascha subsp. huascha
• Echinopsis huascha subsp. robusta(Rausch) Schlumpb.

Distribution

Echinopsis huascha is widespread in the northwest of Argentina in the provinces of Catamarca and La Rioja and grows at altitudes of 500 to 2,000 m (1,600 to 6,600 ft).^{[ citation needed ]}
