Evidentiary scope
The accession rests on fifteen herbarium sheets of plants grown in Mississippi from seed whose labels give Afghanistan as its origin. They show that seed said to be Afghan was grown there; they do not show where in Afghanistan the seed was gathered, who supplied it or how it reached the university. No surviving seed of the lot has been traced. The page therefore carries no locality, coordinates, classification or conservation priority.
Identifier
The identifier UMS-AFG-UNK-0019720001-R1 follows the wiki's seed-accession grammar: holder, ISO 3166-1 alpha-3 country, province segment, month, year, sequence, reproduction suffix.
UMSstands for the University of Mississippi, which grew the lot.AFGis the ISO code for Afghanistan, the recorded seed origin.UNK: no province is recorded.- Month
00: the date the seed was gathered is unknown. - Year 1972 and the sequence are those of Af A (UMS-AFG-UNK-0019720001): a reproduction takes its parent line's identifier.
-R1: the generation the labels state.
Lineage
The labels call Af A1 the first generation of the first seed lot. That lot is Af A, so the accession takes Af A's identifier with the suffix -R1 and Af A as its parent. The labels do not name the parent plants or say in which year the Af A1 seed was harvested. The sourcing type follows the labels' first generation.
Sheet 00947796 (plant 66 B) reads AF a 1 Afghanistan, planted 5 May 1972, with no seed-lot or generation words. It is placed here by the code written on it. Its number differs from the other sheets', which are numbered 51 or carry no number. A second sheet numbered 66, 01564236 (66 A), reads af Afghanistan. planted 5 May 1972 and names no lot; it is not placed on this page.
One sheet coded Af A, 00947916 (plant 52 L), also reads first generation; it stays on Af A (see that page's Talk).
Location and georeferencing
The country field gives the recorded seed origin, Afghanistan, not the place where the plants grew. The grow-out at University, Mississippi, is stated in the article. No coordinate is given and the map is off: a point in Mississippi would misplace Afghan seed, and no place in Afghanistan is recorded.
Dates
The collection date is left empty because the date the seed was gathered is unknown. The sheets are dated 31 July to 1 August 1972, a range across two months, so the sample harvest date is stored as the year. Only one label gives a planting date: 5 May 1972, on sheet 00947796 (plant 66 B). The other labels give none, and the page does not extend that date to them.
Plant numbers
Each numbered 1972 sheet of the lot carries a number of the form 51 A: a figure (51 and 66) shared by groups of sheets of the lot, then one or two letters for the plant. The figure may be a plot or row number, but no label says so, and the article does not call it one.
- Four plant numbers have two sheets each: 51 B, 51 E, 51 H and 51 J.
- Sheet 00947915 has no plant number.
- Harvard credits three sheets (01564235, 01564239 and 01564238; plants 51 B, 51 H and 51 d) to J. F. Maxwell alone, with the same date and garden locality as the rest. The collector field lists him after the three 1972 collectors. The page does not identify him further.
Label reading
The sheets have not been seen. The label text above is Harvard's transcription in its specimen index (read on 12 October 2026), where the lot code is in the remarks field. Harvard has published no image of any sheet of the lot.
- Harvard transcribes the code as AF a 1, AF a1 and af a1; the page writes Af A1.
- The collector field lists the three collectors as Harvard credits them. T. E. Lockwood is Tommie Earl Lockwood (1941–1975) in Harvard's botanist index.
- Harvard dates Small's determination of 01564241 16 February 1986, ten years after the others in the series. The page reports the date as transcribed.
