How many pinnules does a fern have?

The number of pinnules on a fern varies significantly depending on the species. Generally, a single fern frond can have anywhere from a few to several dozen pinnules. Some ferns, like those in the Pteridaceae family, can have deeply dissected fronds with many small pinnules, while others may have broader fronds with fewer, larger pinnules. Ultimately, the specific count is determined by the type of fern.
