Printable list of seed bank holdings (55 pages pdf file)
Small samples of seeds from these accessions are offered free of charge to individuals and organizations involved in plant breeding, research, conservation, and seed exchange. Where stocks are adequate, these samples will contain 25-100 seeds. We ask that you restrict your requests to about 20 samples a year, although some exceptions may be made. For some of our accessions, we have detailed collection information; for others, we have little beyond what is listed below; if you want accession information, please request it with your order. When requesting seeds, please list both taxa and accession numbers, unless there are several accessions with apparently identical information; in the latter case, allow us to choose the particular accession.
Many of our accessions are very small, and we have been unable to evaluate viability; to the degree feasible, please let us know how the seeds perform, and about your experience with the plants.
On a compensated or cooperative basis, we can provide larger quantities of seeds either by grow-out in our fields or greenhouses, or by wild collection. We solicit your suggestions on how we might further develop our seed bank to serve your needs.
While seeds are provided free of charge, DELEP subsists on varied, limited, and uncertain funding. Financial contributions towards supporting our efforts are greatly appreciated. When possible, we ask that you provide us with a FedEx or UPS shipping number to use to cover shipping costs, or you are welcome to send a contribution to cover this expense. We welcome contributions of seeds of taxa of arid and semi-arid region Fabaceae that are not well-represented in the collection. If you are interested in collecting seeds for DELEP on a volunteer basis in areas remote from southern Arizona, please contact us.
International Seed Requests: For shipments of seeds to destinations outside of the U.S., please provide us with full details of shipping instructions and regulations, and any import permits to accompany seed shipments if required by your government. Please note that due to limited resources, DELEP is unable to provide a phytosanitary certificate for seed shipments. If your government requires a phytosanitary certificate, please direct your seed request through USDA-GRIN as they can provide this service.

TAXA: Taxa are listed alphabetically by genus, species and infraspecific taxon. While we endeavor to ensure accuracy, we cannot guarantee that seed accessions are correctly identified. Attribution of seeds is believed to be generally accurate, but some accessions have been received without voucher material, and we lack herbarium resources for the identification of many exotic species. Please let us know if any material you receive appears to be misidentified.
DELEP ACCESSION NUMBERS: Accession numbers are assigned sequentially by year. A suffix "D" indicates seeds collected from plants grown from banked seeds by DELEP in Arizona; in some cases, the parent material has been exhausted, and an entry is provided for information purposes only.
A: Available in adequate quantities for distribution.
B: Available in limited quantities.
C: Available in very limited quantities (usually 2 – 5 seeds). Inquire; in some cases we may have received our stock by exchange or purchase from other distributors, and we may be able to refer you to our sources.
*: An "*" following the letter code for availability indicates that the seeds are subject to the following restriction. Although United States has not ratified the Convention on Biological Diversity (CBD), it is the policy of DELEP that seeds of plants obtained from outside of United States after 31 December 1993 are subject to the provisions of the CBD. Distribution of such seeds will be contingent upon the prior receipt of a waiver of noncommercialization.
