A Cuban vine "communicates" with bat pollinators by emitting an echo through its acoustically-designed leaves. Scientists say the plant is the nocturnal analog of bright flowers that attract visually-oriented pollinators.
In honor of Father's Day, here's a unique 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 and a Cuban native. Along with rum and The Old Man and the Sea, it's a fantastic island export.
