Kinds of Sori
The sori on a given species of fern always takes on the same characteristics. They are usually arranged on the underside of a fertile frond, sometimes in straight lines, sometimes in curved lines, sometimes in circular clumps, and sometimes in kidney-shaped clumps. Because there are a variety of arrangements of the sori, and because the arrangement on each species is somewhat fixed, this characteristic is often used to identify the fern.
