It is (there is no better way to put this) a dead-plant library.Not a library of books about dead plants—though there are books here, and photos and oil paintings—but of plants themselves. They lie in wait on big, stiff sheets of yellowed paper, wrapped gingerly in envelopes and stacked on top of each other, before being inserted into dozens and dozens of cabinets. This is the fifth-largest dead-plant archive in the country, and you can turn a corner and see yards and yards of these cabinets. It is a menagerie of dead plants.
