14) Frond

This is a picture of a Boston fern. Each leaf on a fern is called a frond. A frond is composed of a stalk called the petiole supporting a flattened blade called a lamina. When a fern is growing the fronds are rolled up into small ball shapes. As the plant grows the fronds unroll which is called unferling. There are 3 different types of fronds: simple, pinnatifid, and pinnate.
