The Blaschka exhibit was the one part of the museum I didn't take pictures of (I was rushing at that point), and boy am I sorry! A lot of the pieces on display were actually of diseased plants, and I found it fascinating. I have a book of the Harvard Glass Flowers, but there aren't many of the sick plants shown, or the greatly magnified versions of plant parts. The sheer numbers of these amazing sculptures is incredible, and they're big! You can see how they would be excellent teaching tools.
