What in the World is a Herbarium?

We Googled it: it's a collection of dried plants. That may not sound too exciting, but the New York Botanical Garden's William and Lynda Steere Herbarium is also the center of the Garden's research program. Visit this exhibition to see how scientists are using the 7.8 million specimens in the Steere Herbarium to learn how to sustain plants in the face of global environmental change.
