Digitizing at the speed of light...
The New York Botanical Garden recently added the three-millionth plant specimen to the Virtual Herbarium, part of an ambitious project to digitize the 7.8 million dried plant specimens in its William and Lynda Steere Herbarium, the largest herbarium in the Western hemisphere. Of all specimens digitized, most are vascular plants, but brophytes, algae, fungi and lichens are the focus of many of our digitization projects.
