A "bead fern" is a type of plant, specifically a fern, that is found in eastern North America and eastern Asia. This fern has beautiful, spreading leaves (called fronds) that can fold slightly when you touch them. The small parts of the leaves, called pinnules, have groups of spore cases (called sori) that look like little beads.
