Page scope

UMS-VNM-UNK-0019720002 is an Accession — the atomic unit of documentation representing a specific collection event. All scientific data lives here.

Evidentiary scope

The accession rests on 5 herbarium sheets of plants grown in Mississippi from seed whose labels give Vietnam as its origin. They show that seed said to be Vietnamese was grown there; they do not show where in Vietnam 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-VNM-UNK-0019720002 follows the wiki's seed-accession grammar: holder, ISO 3166-1 alpha-3 country, province segment, month, year, sequence.

UMS stands for the University of Mississippi, which grew the lot.
VNM is the ISO code for Vietnam, the recorded seed origin.
UNK: no province is recorded.
Month 00: the date the seed was gathered is unknown.
Year 1972 is the year of the earliest dated sheet of the lot. The seed had reached the university by then; the year is not a collection date.

Lineage

One label calls V B the original sample, which reads as seed grown as received, without an intervening generation in Mississippi. The seed's own history before it reached the university is unknown, so the sourcing type is Unknown provenance. No parent accession is set.

Location and georeferencing

The country field gives the recorded seed origin, Vietnam, 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 Vietnamese seed, and no place in Vietnam 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. The planting date, 21 March 1972, comes from the labels.

Plant numbers

Each 1972 sheet of the lot carries a number of the form 85 A: a figure shared by every sheet of the lot, then a letter 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.

Label reading

The sheets have not been seen. The label text above is Harvard's transcription in its specimen index (read on 8 October 2026), where the lot code is in the remarks field. Harvard has published no image of any sheet of the lot.

Plant 85 C has three sheets, 86 G and 86 I two each.
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.

M. W. Quimby, N. J. Doorenbos, C. E. Turner and A. Masoud described the cultivation and the morphological variation of Mississippi-grown cannabis in Economic Botany 27 (1973): 117–127 (doi:10.1007/BF02862224). The paper may identify the seed sources and explain the lot codes. It has not been read for this page, and nothing here depends on it.
