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]

Taxonomy

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]

As of October 2023, Plants of the World Online accepted the following species:[1]
