This is the largest herbarium at NTNU University Museum, containing specimens mainly from Norway and the Nordic countries. Most of the specimens are collected in Central Norway. In addition, the vascular plant herbarium contains around 30 000 specimens from the rest of the world.

One of the oldest parts of the collection consist of the herbarium after bishop Gunnerus (1718-1773), which laid the foundation for the first national flora “Flora Norvegica” published by Gunnerus in 1766.

Another significant part of the collection is the Arctic collection from Alaska and Canada by Professor Olav Gjærevoll consisting of about 6 000 specimens.

Among the main bulk of specimens from central Norway the Dovrefjell Mountain region is especially well represented. You also find a focus on documentation of the expansion of non-native species in the flora especially by the collections by Eli Fremstad.

The collection includes more than100 type specimens.
