filicology

[prettygoodword]

filicology (fil-uh-KOL-oh-jee) - n., the botanical study of ferns.



Thanks, WikiMedia!

Better known as pteridology, the difference being this is from Latin filix, fern, instead of Ancient Greek ptéris, fern. Since -ology is from Ancient Greek too, I suppose pteridology is the more well-formed word, but I still like this one better.
