Abstract
Abstract: A solitary plant of the putative intercladal cross Echinopsis (Leucostele) atacamensis subsp. atacamensis × Echinopsis (Soehrensia) formosa was observed in the contact zone of the mostly allopatric populations of the parent species in the Salar de Atacama region in the Chilean Andes. The plant is intermediate between the parents in its characters. It was found to be sterile, despite normal-looking anthers (with abundant pollen) and stigma. In addition, an apparently typical individual of E. atacamensis with yellow flowers has been found, but it remains unknown whether this is merely a flower colour variant, or whether hybridization could be involved.
