(from l-r) Jon Sholle takes a picture and Hozan Alan Senauke and Laurie Senauke look at a plant specimen collected during the Lewis and Clark Expedition (1804) while Nicole Tarnowsky, Herbarium Curator, describes some of the finer points of the collection. With over 7 million specimens, the William and Lynda Steere Herbarium at The New York Botanical Garden is the largest herbarium in the Western Hemisphere. Amazing herbarium. Wonderful group of people.
