Grant Expands Access

Accession Card

As part of a grant from the Institute of Museum and Library Services, all historic accession cards, from Abeliophyllum to Zizyphus, have been reviewed and incorporated into BG-BASE, resulting in almost 70,000 new and over 100,000 edited records. In addition, 1,700 map documents (ca. 1937–1988) representing 1,982 locations have been digitized and georeferenced.

Legacy Collection Statistics

As of August 2014, the legacy (dead) collections comprised 65,195 accessions representing 17,462 taxa. Of these, 63,874 individual plants (including nursery holdings) belonging to 43,102 accessions representing 13,632 taxa were inventoried within the living collections before perishing. Taken together, the collections are considered to be one of the largest (Table 1) and best documented (Table 2) woody plant collections in North America and the world. Many of these accessions or accession lineages are of historical and botanical importance, representing the original North American introductions of Eastern Asian plants collected by Arboretum staff and affiliates such as Charles Sprague Sargent, Ernest H. Wilson [pdf], John G. Jack [pdf], Joseph Rock [pdf], and William Purdom [pdf].
