If you gaze long into a forest ... the forest also gazes into you. With apologies to Nietzsche, we found these eye-like objects staring back up at us from a rich northern hardwood forest floor in Thetford, Vermont. What are they?
Answer
These are the upturned, fertilized flowers of ghost pipe (Monotropa uniflora), also called Indian pipe, a non-photosynthesizing plant that draws its sustenance from mycorrhizal fungi, which in turn pull nutrients from trees. Once ghost pipe flowers have been pollinated, they turn upright, and the entire plant begins to darken. You can learn more about them in this Outside Story essay by Edna Greig.
