California Snow Flower
I've photographed a number of parasitic flowers that have a symbiotic relationship with a photosynthesizing host but had only heard rumor of the plant kingdom's ménage à trois, up until now. This snow flower is one of those threesomes. It taps into a symbiotic fungus that relies on a photosynthesizing plant and becomes a third party or "mycorrhizal cheater". Although the description doesn't sound flattering, they are quite the wonder to stumble upon. Northern California, USA.
