Soehrensia walteri explained

Soehrensia walteri is a species of Soehrensia found in Argentina.^[1]

Description

Soehrensia walteri typically forms groups of spherical, green shoots, each up to 16 cm in diameter and height. It has about eleven ribs, each 1.5 to 2.5 cm wide, with whitish areoles. From these areoles, 5 to 15 flexible, needle-like yellow spines emerge, each 1 to 2.5 cm long.

The bell-shaped, yellow flowers are slightly fragrant and appear from the youngest areoles near the shoot apex, opening during the day. They are 7.5 to 9 cm long and up to 9 cm in diameter. The spherical, greenish-yellow fruits are 1.7 to 2 cm long and 2 to 2.5 cm in diameter.^[2]

Distribution

Soehrensia walteri is found in the Argentine province of Salta, specifically in the Quebrada de Escoipe, at altitudes of 2000 to 2500 meters.

Taxonomy

First described as Lobivia walteri by Roberto Kiesling in 1976, the species name honors Austrian cactus specialist Walter Rausch.^[3] Boris O. Schlumpberger reclassified it into the genus Soehrensia in 2012.^[4]
