I don’t feature nearly enough plants on this site, and that’s because I was trained as a zoologist and don’t know much about botany.
But here’s a nice specimen. It’s the beautiful snow plant (Sarcodes sanguinia), a plant without chlorophyll. It’s a saprophyte, which means it lives on dead or decaying organic mater, and steals nutrients from the roots of pine trees via a shared underground fungus.
Let the rangers of California’s Yosemite National Park explain it to you:
By the way, my collections of fruit flies in America’s national parks taught me that the rangers, and especially the ranger-naturalists, are a tremendous resource for the visitor interested in science. By all means take advantage of their expertise if you visit the parks. They love to answer questions about geology and biology, which are a welcome break from inquiries like “where are the restrooms?” and “can we bring guns here?”
