Soehrensia huascha, is a species of Soehrensia in the Cactaceae family, found in north western Argentina. ^[2] First published in Cactaceae Syst. Init. 29: 5 in 2013. ^[2]

Was formerly thought to be a species of Echinopsis . ^[3]

Description

The plants usually branch at the base and form low groups with heights of up to 1 meter. The cylindrical, fresh green, upright or creeping trunks with an erect shoot tip have 14 - 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 - 3 central spines are slightly thicker than the radial spines and are between 2 and 7 cm (2.8 in) long. The 9 to 11 radial spines are up to 1.5 inches 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). ^[4]

Taxonomy

The first description as Cereus huascha was published in 1893 by Frédéric Albert Constantin Weber. ^[5] The specific epithet huascha is derived from a local Argentine word meaning orphan. Boris O. Schlumpberger placed the species in the genus Soehrensia in 2013. ^[6] Further nomenclature synonyms are Trichocereus huascha (F.A.C.Weber) Britton & Rose (1920), Lobivia huascha (F.A.C.Weber) W.T.Marshall (1938), Helianthocereus huascha (F.A.C.Weber) Backeb. (1951), Salpingolobivia huascha (F.A.C.Weber) Y.Itô (1957) and Echinopsis huascha (F.A.C.Weber) H.Friedrich & G.D.Rowley (1974). There are numerous other synonyms.
