Page scope

UMS-THA-UNK-0019710001 is an Accession — the atomic unit of documentation representing a specific collection event. All scientific data lives here.

Evidentiary scope

The accession rests on one herbarium sheet of plants grown in Mississippi from seed whose label gives 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-0019710001 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 1971 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 label gives the code Ti D1 and no generation. On the three 1972 sheets coded Ti D1 (UMS-THA-UNK-0019720003) the same code is glossed as the first generation of the fourth Thai seed lot. This sheet is kept as its own accession: it comes from an earlier season, and its label does not say whether the 1971 plants grew from the same seed as the 1972 ones. Because the label itself states no generation, the sourcing type is Unknown provenance. 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. 14 October 1971, the date of the sheet, is entered as the sample harvest date.

Label reading

The sheet has 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.

The sheet carries no collector number.
The sheet gives 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.
