In honor of Father's Day, here's a hirsute tree that goes by the name Old Man Palm (Coccothrinax crinita). Covered in long fibers (crinita means hairy in Latin) that resemble a tremendous beard, the rare species is a favorite among palm collectors. The tree is also known as the "Old Man from Cuba," where it is native and endemic. I know what you're thinking—a beard under the Cuban sun? Why, it's a palm for Ernest Hemingway.
