Joseph F. Rock Herbarium (HAW)
Founded in 1908, the Joseph F. Rock Herbarium (HAW) serves as the official university repository for botanical plant specimens. It is the result of decades of plant exploration by some of the leading researchers in the Pacific basin and collections continue to expand.The herbarium comprises approximately 50,000 dried preserved plant specimens.
The mission of the herbarium is to maintain and expand the collection to provide a thorough representation of Hawaiian and Pacific Island flora, with particular emphasis on vascular plants. For more than 100 years, the herbarium has been a focal point for teaching, training, and education on the flora of Hawai’i and the Pacific.
The Joseph F. Rock Herbarium houses and maintains voucher specimens of plants that reflect the teaching, research, and project efforts of faculty, staff, and students at UH Manoa. The Lyon Arboretum herbarium (HLA), which included more than 8000 specimens of cultivated plants was merged with HAW in 2005 as part of an NSF award. The Lyon Arboretum collection includes native Hawaiian flora and introduced accessions collected on the grounds of Lyon Arboretum.
