Whether Maihueniopsis mandragora should be regarded as a synonym – see there.
The species was described in 1935 by Backeberg as Tephrocactus minutus. Backeberg gives “N-Argentinien (Los Andes)” as finding place. The plants that R. Kiesling later mentioned from the finding place “AR Jujuy, Humahuaca, Palca de Aparzo” are most probably those plants that nowadays are called Maihueniopsis molfinoi.
Recently plants from west of Fiambala, Catamarca, AR are regarded as Maihueniopsis minuta. We want to show some of them here.
