Evidentiary scope

The accession rests on two sources: the department's printed inventory entry for plant introduction 10979 (Inventory No. 11 (1907), p. 43) and the entry for PI 10979 in GRIN-Global, the database of the National Plant Germplasm System, as it stood on 27 October 2026. The inventory names the city, the donor and the exchange, and nothing more. GRIN-Global states that the lot "no longer exists and can not be requested", so the page gives the lot as gone. No conservation priority is assigned.

Identifier

The identifier NPG-CHN-SNX-0019040001 follows the wiki's seed-accession grammar: holder, ISO 3166-1 alpha-3 country, province segment, month, year, sequence. The department's own number for the lot is PI 10979.

NPG stands for the National Plant Germplasm System of the United States Department of Agriculture, whose database, GRIN-Global, carries the department's plant introductions.
CHN is the ISO code for China.
SNX stands for Shaanxi.
Month 00: the date the seed was gathered is not known.
Year 1904 is the year the department received the lot.
0001 is the lot's place, in plant-introduction order, among the holder's lots from the same country, province, month and year.

Classification

The seed came in an exchange of seeds from a city, and neither source says where it was grown or by whom, so the accession is classified Unknown.

Collectors and donors

GRIN-Global lists W. W. Simpson as its source; the printed inventory says he presented the seed in exchange for American vegetable seed. No one is said to have gathered it, so the infobox gives no collector.

Location and georeferencing

The inventory names Hsi-an, today's Xi'an, and nothing finer. The point 34.26, 108.94 is the point OpenStreetMap gives for the city of Xi'an (relation 3226004), a locality georeference for the place the source names, not a collection point. Basis: settlement point. Uncertainty: about 10 km, the radius of today's central city, larger than the walled city of 1904. The province is the one GRIN-Global gives.

Dates

The date the seed was gathered is not known, so the collection date is empty. Both sources give 23 May 1904 as the date of receipt, the lot's received date. The identifier therefore carries month 00 and the year of receipt.
