Herbarium Pacificum (BISH)
Founded in 1889, Herbarium Pacificum holds specimens of all of the native, alien, and cultivated plants in Hawai‘i — including many “last-known” collections of the 89 Hawaiian species pushed to extinction in the last two centuries — alongside a reference collection of over 125,000 specimens from around the world. In 1992, the Hawai‘i State Legislature designated the herbarium as the primary repository for plant vouchers in the State.
The collections include angiosperms (381,400), algae (82,200), ferns (45,900), mosses (13,600), fungi (8,300), liverworts (5,800), gymnosperms (2,700), lichens (2,400), wood, and fossils. Among the earliest collections ever made in Hawai‘i are those of David Nelson, naturalist on Captain Cook’s third voyage, and the Tanager, Mangareva, and Whitney expeditions.

Research
A working herbarium
The herbarium is not just a place to preserve plant specimens — it is a place of active research. Museum botanists study the evolution, ecology, and ethnobotany of Pacific plant life, assist state and federal agencies with plant identification, and have produced foundational works from the Manual of the Flowering Plants of Hawai‘i to Isabella Aiona Abbott’s La‘au Hawai‘i and the marine algal floras of the Hawaiian Islands. It is equally likely the herbarium holds unidentified specimens representing species currently unknown to science.
