Evidentiary scope

The accession rests on two herbarium sheets of plants grown in a greenhouse at Indiana University, Bloomington, from seed whose label gives Thailand as its country of origin. They show that seed recorded as Thai was grown there in 1996; they do not show where in Thailand the seed was gathered, when, or by whom. No surviving seed of the lot has been traced. The page therefore carries no locality, coordinates, classification or conservation priority.

Identifier

The identifier IUB-THA-UNK-0019960003 follows the wiki's seed-accession grammar: holder, ISO 3166-1 alpha-3 country, province segment, month, year, sequence.

  • IUB stands for Indiana University, Bloomington, which grew the plants and whose herbarium holds the sheets. The herbarium's Index Herbariorum acronym is IND; it is not used in the identifier because IND is also the code for India.
  • 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 1996 is the year of the sheets. The seed had reached Indiana University by then; the year is not a collection date.

Lineage

Th-4 is Hillig's parallel code for the lot, and 91-172.8 the source code under which HortaPharm B.V. supplied the seed. The page reproduces both codes and does not interpret them. The two sheets share the parallel code, the source code and the season, so they are one accession; the label calls one rep. 1 and the other rep. 2, which the page reproduces without interpreting. No label gives a generation, so the sourcing type is Unknown provenance. No parent accession is set.

Georeferencing

No point is given. The plants were grown in a greenhouse in Bloomington, Indiana, and the label records Thailand as the seed's country of origin without naming any place within it. The country field carries that origin; no province is set and the map is off.

Label reading

The sheets were read from the herbarium's photographs on 12 October 2026. The typed label agrees with the transcription in the Consortium of Midwest Herbaria portal, which lists the university number as the catalogue number. The portal records no determiner; the name on the page is the printed label's. The portal's Source cod& on IND-0149685 is a transcription slip; the sheet reads as printed above. The portal's Germ, date is a slip for the label's Germ. date. What the photographs show is described here and not in the article: IND-0149685 shows a flowering branch that appears pistillate and a separate stem segment pencilled node 3. IND-0149687 shows a flowering branch that appears pistillate and a separate stem segment pencilled node 3.


The infobox gives the maximum height as 2.60 m, the label's 260 cm tall on IND-0149685 converted to metres. IND-0149687 gives no height. The label's vegetative stem aroma names a characteristic but describes no scent, so the aroma field is left blank. The label's weak branching is quoted in the article; the branching field is left blank because its allowed values (Minimal, Moderate, Extensive, Apical dominant) are not the label's grades.

Sources not yet read

The passport data and accession codes of Hillig's collection were published in his paper Genetic evidence for speciation in Cannabis (Cannabaceae), Genetic Resources and Crop Evolution 52 (2005): 161–180 (doi:10.1007/s10722-003-4452-y), which may explain the source and parallel codes. It has not been read for this page, nor has K. W. Hillig and P. G. Mahlberg's 2004 paper on cannabinoid variation in the American Journal of Botany, nor Hillig's 2005 dissertation. Nothing here depends on them. No published paper is cited for the morphometric analysis that the labels name.
