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.[1]
The genus was established by Curt Backeberg in 1938.[1]
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.[2]
Studies in the 1970s and 1980s resulted in several formerly separate genera being absorbed into Echinopsis, including Soehrensia and Helianthocereus,[3] until it was re-assessed to be a separate genus.[4] [5]
