Page scope

UMS-THA-UNK-0019700001 is an Accession — the atomic unit of documentation representing a specific collection event. All scientific data lives here.

Evidentiary scope

The accession rests on four herbarium sheets of plants grown in Mississippi from seed whose labels give Thailand as its origin. They show that seed said to be Thai was grown there; they do not show where in Thailand 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-THA-UNK-0019700001 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.
THA is the ISO code for Thailand, the recorded seed origin.
UNK: no province is recorded.
Month 00: the date the seed was gathered is unknown.
Year 1970 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

The four sheets carry two codes, MS-SM and MS-SO, and are one accession because every label carries the same seed note: Thailand Marihuana Seed, 17 January 1970, reference 65471. The two codes may mark two sowings of that seed; the labels do not say. Neither label gives a generation, so the sourcing type is Unknown provenance. No label explains the date or the reference letters QCD (transcribed QDC on sheet 01005560), and the page does not interpret them. No parent accession is set.

Location and georeferencing

The country field gives the recorded seed origin, Thailand, 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 Thai seed, and no place in Thailand is recorded.

Dates

The collection date is left empty because the date the seed was gathered is unknown. The sheets are dated 12 August, 19 September and 11 October 1970, so the sample harvest date is stored as the year. 17 January 1970, the date in the seed note, is not entered as a collection date: the label does not say what it marks.

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.

No sheet carries a collector number.
The sheets give the vernacular names hemp, Indian hemp, fimble, gallow grass, grass marihuana, marihuana, hanf, chanvre, and others, a general list that says nothing of Thai usage, so it is not entered as a local name.
Harvard's botanist index lists the collector as Quimby, Mayhard Ward (born 1905), also known as M. W. Quimby. His 1973 paper in Economic Botany gives his first name as Maynard.

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.
