Pteridophytes of Wisconsin: Ferns and Fern Allies

This web site is provided for those interested in the ferns and fern allies or "pteridophytes"of Wisconsin. The fern allies include horsetails, club mosses, spikemosses, and quillworts. The goal is to provide a key to all native Wisconsin pteridophytes with photos and descriptions to help with their identification.

For the beginning student of the pteridophytes it may be best to begin at the introduction to the basic anatomy of pteridophytes and the terminology commonly used in referring to them. The reader may then go to the key to pteridophytes to identify an unknown plant, or go directly to a list of Wisconsin's pteridophytes with links to pages for the individual species. Each species has a page containing photos of important features and some basic information regarding habitat and distribution. A separate glossary of pteridophyte terms is also provided. This is a work in progress and editing and expansion of the sections will continue indefinitely. Feedback on omissions, typos, and the usefulness of the site are appreciated.
