Bryophytes at the Natural History Museum, University of Oslo.

The bryophyte herbarium at the Botanical Museum, the University of Oslo, comprises a Norwegian herbarium (ca. 185,000 specimens, of which ca. 100,000 mosses, ca. 15,000 peat mosses and ca. 35,000 hepatics), a general herbarium (ca. 80,000), a type herbarium with ca. 100 types and a collection of older exsiccata (ca. 5,000 specimens).

The herbarium contains important material among others from Norway, the Arctic, Macaronesia and Tristan da Cunha. Important collectors are Matthias Numsen Blytt (1789-1862), Søren Christian Sommerfelt (1794-1838), Christian Kaurin (1831-1898), Frantz Caspar Kiær (1835-1893), Nils Gregers Ingvald Wulfsberg (1847-1888), Elling Ryan (1849-1905), Baard Bastian Larsen Kaalaas (1851-1917), Ingebrigt Severin Hagen (1852-1917; in part), Nils Bryhn (1854-1916; in part), Eugen Honoratius Jørgensen (1862-1938; in part), Johannes Lid (1886-1971) and Per Størmer (1907-1991).
