Snow Flower (Sarcodes sanguinea). A parasitic plant that lacks chlorophyll. It derives its sustenance and nutrients from a fungi that attach to roots of trees. Image taken with a Nikon D3x camera and 45 mm f/2.8 PC-E lens (ISO 100, 45 mm, f/8, 1/13 sec).
I noticed something bright red in the woods when driving into Yosemite National Park. I had never seen these before, and initially thought they were some type of mushroom. The flowers however gave it away as a plant.
