Echinopsis huascha

A clumping, columnar to sprawling cactus (also known as Trichocereus huascha) from Catamarca and La Rioja in northwest Argentina, at 500–2,000 m. It bears large funnel-shaped day flowers. The measured climate here comes from an Australian record of a plant that is almost certainly cultivated or naturalised, so it does not describe the native habitat.
