To the wandering bird, bee, or insect, a flower is both a billboard and a wayfinding sign—its colors and patterning have evolved to attract pollinators and direct them towards the plant's pollen and nectar. There's one prerequisite: the visual cues require a diurnal pollinator to find the flower. What about bats, then? How do nocturnal, echolocating pollinators navigate a floral terrain? According to an article in Science, they may use acoustics.
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.
