Evidentiary scope

The accession rests on two sources: the department's printed inventory entry for plant introduction 3667 (Inventory No. 8, p. 32) and the entry for PI 3667 in GRIN-Global, the database of the National Plant Germplasm System, as it stood on 27 October 2026. The inventory names the city the seed came from and the man it came through, 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-TUR-IST-0018990001 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 3667.

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.
TUR is the ISO code for Turkey.
IST stands for Istanbul Province.
Month 00: the date the seed was gathered is not known.
Year 1899 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 inventory names the city the seed came from and says nothing of the crop or of who grew it, so the accession is classified Unknown.

Collectors and donors

GRIN-Global lists Walter Tennyson Swingle as its source; the printed inventory says the seed was received through him, under his number 136. Neither source says he gathered it, so the infobox gives no collector.

Location and georeferencing

The inventory names Constantinople and nothing finer. The point 41.02, 28.95 is the point OpenStreetMap gives for Fatih, the historic peninsula of Istanbul (relation 1766104), a locality georeference for the place the source names, not a collection point. Basis: settlement point. Uncertainty: about 8 km, taking in the city of 1899 on both sides of the Golden Horn. The province is the one GRIN-Global gives.

Dates

The date the seed was gathered is not known, so the collection date is empty. The inventory gives the month of receipt, July 1899. GRIN-Global gives 7 July 1899, which agrees with it and is used as the lot's received date. The identifier therefore carries month 00 and the year of receipt.
