Here is another Echinocereus hybrid. One parent is definitely has coccinneus line in it, as you can see by a flower shape. It is also clearly dioious-female plant with no pollen produced. Cross-pollination with the white hybrid resulted in a fruit with lots of seed.
I do not know what species were crossed to make this hybrid, as I bought it as a plant. In any case, I'm curious to see the flowers of the next generation of plants.
