Rebutia kariusiana Wessner

Regarded by some as a bright green form of Rebutia marsoneri with pale pink flowers. Plants in cultivation come from a single collection together with R. marsoneri, but not subsequently refound in the wild. Found to be distinctive enough to be given specific status by Mosti & Papini (2011).
