Soehrensia is a large genus of cacti native to South America.
It is found in Peru, Bolivia, Chile, Paraguay and northern Argentina.[1]
The genus was circumscribed by Curt Backeberg in Blätt. Kakteenf. vol.5 (6) on page 7 in 1938.[1]
The genus name of Soehrensia is in honour of Johannes Soehrens (he 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]
