Soehrensia formosa, is a species of Echinopsis found in South America. In north-western Argentina, Bolivia and northern Chile.[2] First published in Cactac.: Handb. Kakteenk. 3: 1678 in 1959.[2]
Description
[edit]Soehrensia formosa grows solitary at first, later occasionally branching out from the base and then forming groups. The spherical to cylindrical, light green to blue-green shoots reach heights of growth of up to 1.5 meters with a diameter of 25 to 50 cm (9.8 to 19.7 in). There are 27 to 50 rounded ribs that are clearly notched and tuberous. The dark areoles located on them are up to 1 cm (0.39 in) apart. Needle-like, yellowish to reddish-brown thorns emerge from them. The two to nine central spines are 3 to 20 cm (1.2 to 7.9 in) long. The nine to 15 radial spines are spread out, straight or slightly curved and have a length of up to 3 cm (1.2 in).
The broad, funnel-shaped, red to orange-red to yellow flowers appear near the top of the shoot and are open during the day. They are 6 to 9 cm (2.4 to 3.5 in) long and have the same diameter. The broad, spherical, green fruits are up to 3 cm (1.2 in) long and 4 cm (1.6 in) in diameter.[3]
Subspecies
[edit]Has 5 Accepted subspecies;[2]
- Soehrensia formosa subsp. formosa
- Soehrensia formosa subsp. kieslingii (Rausch) Schlumpb.
- Soehrensia formosa subsp. korethroides (Werderm.) Schlumpb.

Distribution
[edit]Soehrensia 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.
Taxonomy
[edit]The first description as Echinocactus formosus by Ludwig Georg Karl Pfeiffe was published in 1837.[4] The specific epithet formosa is derived from the Latin word formosus for 'stately' and refers to the appearance of the plants. Boris O. Schlumpberger placed the species in the genus Soehrensia in 2012.[5] Further nomenclature synonyms are Echinopsis formosa (Pfeiff.) Jacobi ex Salm-Dyck (1850), Acanthocalycium formosum (Pfeiff.) Backeb. (1936), Lobivia formosa (Pfeiff.) Dodds (1937) and Trichocereus formosus (Pfeiff.) F.Ritter (1980). Was once thought to be a species of Echinopsis.
