Soehrensia

Soehrensia is a genus of cacti native to South America.

It is native to northern Argentina, Bolivia, northern Chile, Paraguay and Peru, and has been introduced elsewhere, including Mexico, southern Africa and Spain.

Taxonomy
The genus was established by Curt Backeberg in 1938.

The genus name of Soehrensia is in honour of Johannes Soehrens (died 1934), who was a Dutch botanist and Professor and Director of the Botanical Garden in Santiago de Chile. He was an authority on cacti.

Studies in the 1970s and 1980s resulted in several formerly separate genera being absorbed into Echinopsis, including Soehrensia and Helianthocereus, until it was re-assessed to be a separate genus.
