Currently, 46,672 voucher specimens (35% of total) document the historic as well as extant living collections.  And, of 10,257 extant accessions in the living collection, half (5,187) are supported by at least 1 voucher specimen.  Approximately five hundred vouchers are added to the collection annually with a current focus placed on NAPCC genera (Table 2).
