I wanted to mention a great website for people interested in plants, particularly of the U.S. Southeast. It's called NameThatPlant.net, and it is "a clearinghouse of information about native and naturalized plants of the Carolinas and Georgia." Of course, many of the plants on the site have ranges outside of those states, so it's a resource worth knowing about. I recently contributed a bunch of photos of ferns, as well as audio files of about a hundred plant name pronunciations, so if you explore a bit you might come across me reciting the name of, say, Asplenium trichomanes ssp. trichomanes. It's a fun site, go visit.
