Its former species are [[Native species|native]] to northern [[Argentina]], [[Bolivia]], northern [[Chile]], [[Paraguay]] and [[Peru]], and have been introduced elsewhere, including Mexico, southern Africa and Spain.
==Taxonomy== The genus was established by [[Curt Backeberg]] in 1938.<ref name=IPNI_295134-2>{{IPNI|taxon=''Soehrensia'' |authority=Backeb..|id=295134-2|access-date=2025-11-22|mode=cs1}}</ref> The genus name ''Soehrensia'' is in honour of Johannes Soehrens (died 1934), who was a Dutch [[botanist]] and Professor and Director of the Botanical Garden in [[Santiago|Santiago de Chile]].
