The Massey Herbarium (VPI) at Virginia Tech is an active and growing collection that seeks to represent the floristic diversity of the central Appalachian and Mid-Atlantic regions. Growing from a small teaching collection, the herbarium was established as a state repository in 1927. As of 2022, accessioned vascular plant specimens numbered 111,000. It is estimated that about 65% are from Virginia, the balance from all parts of North American. Groups particularly well represented are ferns (especially Isoetes), Poaceae, Cyperaceae (especially Carex), and Asteraceae (Eupatorium, Packera, Solidago).
