My girlfriend Jane (who's made of awesome) took the Plant Identification Challenge. She thinks it's "probably a parasitic/saprophytic plant. Of the available choices, I think by far the most likely is the saprophytic orchid Corallorhiza maculata, spotted coralroot. http://en.wikipedia.org/wiki/Corallorhiza_maculata"

She suggests this website: "http://www.botany.org/Parasitic_Plants/ for some other choices (but this site does not have a link to this orchid)."

She concludes: "Thanks honey, that was fun!"
