Herbarium of Cultivated Plants Statistics
As of January 2016, the Herbarium of Cultivated Plants comprised 129,199 specimens. This collection contains vouchers collected from non-Arnold Arboretum (AA) sources, as well as accessions that grow or once grew in the living collections (Table 1).
Currently, 48,204 voucher specimens (37% of total) document the historic as well as extant living collections. And, of 10,506 extant accessions in the living collection, nearly half (5,090) are supported by at least 1 voucher specimen. Approximately five hundred vouchers are added to the collection annually with a current focus placed on Plant Collections Network genera.
Management of the collection is guided by the Cultivated Herbarium Collections Policy [pdf].
