Echinocereus coccineus flower

Here are flowers of Echinocereus coccinneus species. They are smaller then hybrid blooms, and the color is pure  crimson red, with throat that lacks pigment, and sometimes green. This is gioious-male plant with lots of pollen produced.
Nice thing about E. coccinneus, usually inherited by it's hybrids, is a long flowering duration. Flowers do not close for night and blooms stay open for about a week.
