Evidentiary scope

The accession rests on two sources: the department's printed inventory entry for plant introduction 42166 (Inventory No. 46 (1919), p. 59) and the entry for PI 42166 in GRIN-Global, the database of the National Plant Germplasm System, as it stood on 27 October 2026. The inventory names the nursery and the channel, and prints two notes on the hemp: one by S. Iida on its growing and its use, and one by L. H. Dewey. 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-JPN-TOC-0019160001 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 42166.

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.
JPN is the ISO code for Japan.
TOC stands for Tochigi Prefecture.
Month 00: the date the seed was gathered is not known.
Year 1916 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

Iida's note describes Tochigi hemp as a crop grown by farmers for their own local needs, from which seed was scarce, so the accession is classified Landrace.

Collectors and donors

GRIN-Global lists the Yokohama Nursery Company Limited among its sources; the printed inventory says the seed was procured from the company through Dewey. No one is said to have gathered it, so the infobox gives no collector. S. Iida, who wrote the first note, is not identified further in the inventory.

Location and georeferencing

The notes name the province of Tochigi and nothing finer, and the inventory heads the lot "From Yokohama, Japan", the nursery's city. The prefecture is the finest place of production named. Province-level points are not yet in use, so the page has no point and the map is off. GRIN-Global gives Kanagawa, the nursery's prefecture; the province entered is the one the notes name.

Dates

The date the seed was gathered is not known, so the collection date is empty. Both sources give 18 March 1916 as the date of receipt, the lot's received date. The identifier therefore carries month 00 and the year of receipt.
