Down in Mexico, it made the news that about 30 years ago scientists looked into a village which grew corn 20 feet high. It was of interest to them, because it seemed to have figured out how to fertilize itself. It's a wild story.

It's totally plausible that cultivars and species are in some crazy rural pocket and not well known. I'm coming to appreciate the idea that despite everyone being connected to a global computer network with a camera device, not everything has found its way into the realm of scientific knowledge. What other plants and animals might be out there?
