Description

Soehrensia formosa grows singly 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 centimeters. There are 27 to 50 rounded ribs that are clearly notched and tuberous. The dark areoles located on them are up to 1 centimeter apart. Needle-like, yellowish to reddish-brown thorns emerge from them. 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 top of the shoot and are open during the day. They are 6 to 9 centimeters long and have the same diameter. The broad, spherical, green fruits are up to 3 centimeters long and 4 centimeters in diameter. [3]

Taxonomy

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 .
