I have been reading a bunch of gardening books so I can write something about them in my blog so that my blog can be utilized in filling our e-newsletter. This is about the one I just finished.
Oliver Sacks writes about a fern "field trip" the American Fern Society took to Oaxaca in 2000. The book is delightfully written and is more about the members of the fern society which meets in NYC than about esoteric ferns but it does sound like Oaxaca is full of ferns. Dr. Sacks is a neurologist from NYC--also a well known aurthor-- who started going to the meetings of the AFS as an amateur fern enthusiast, and then went on their field trip.
