Bridges' cliffbrake (scientific name: Pellaea bridgesii) is a type of fern. It gets its common name from growing on cliffs. This fern is found in the western United States. You can see it from northern California all the way to Idaho. It likes to grow on rocky cliffs and slopes, especially those made of granite.
About Bridges' Cliffbrake
Bridges' cliffbrake grows from a special underground stem called a rhizome. This rhizome is brown and branches out, helping the fern spread. Each leaf of the fern can grow quite long, up to 30 or 35 centimeters (about 12 to 14 inches).
What the Leaves Look Like
The leaves of this fern have a straight, brown main stem called a rachis. Along this stem, you'll find many small, leathery leaflets. These leaflets are a pretty blue-green color and are spaced out. They are usually round or oval, and sometimes they look like they are folded over.
A cool thing about Bridges' cliffbrake is how its leaflets are. Unlike some other ferns, the edges of these leaflets do not curl under. This means they don't cover the tiny cases called sporangia that are found on the underside of the leaves. Sporangia hold the fern's spores, which are like tiny seeds that help the fern reproduce.
