University of New Mexico Herbarium (UNM-Vascular Plants)

Bionomia dataset badge
The Museum of Southwestern Biology houses New Mexico’s largest herbarium. Our focus is mainly to document and preserve a record of the flora of the state. We have 130,000 specimens; most are from New Mexico and the southwestern U.S. Our primary international holdings are from Mexico. As the fifth largest state we are relatively unexplored and species new to science are still being discovered, documented, and described. Our specimens represent over 7700 species and serve as a reference for what’s been documented within our region.
