Evidentiary scope

The accession rests on one herbarium sheet of a plant grown in a greenhouse at Bloomington, Indiana, from seed whose label gives its origin as Thailand (Sakon Nokhon) and its source as HortaPharm B.V. of Amsterdam. It shows that seed said to come from Sakon Nakhon was grown to flowering in 1995; it does not show who gathered the seed, where in Sakon Nakhon, from what kind of plant, when or how it reached HortaPharm. 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-SAK-0019950001 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 plant and whose herbarium holds the sheet. The herbarium's Index Herbariorum acronym is IND; it is not used here because IND is also the ISO code for India.
  • THA is the ISO code for Thailand, the recorded seed origin.
  • SAK is the first three letters of Sakon Nakhon.
  • Month 00: the date the seed was gathered is unknown.
  • Year 1995 is the year of the sheet. The seed had reached Indiana by then; the year is not a collection date.

Lineage

The label gives two codes. Th-2, the parallel code, is the code under which the sheets of this lot are grouped: it is on this sheet and on both sheets of the 1996 season (IUB-THA-SAK-0019960001), although those carry two different source codes. The source codes, 91-170.22 here and 91-170.20 and 91-170.22 in 1996, are reproduced as written and not interpreted. The 1995 and 1996 seasons are separate accessions. Neither label gives a generation, so the sourcing type is Unknown provenance. No parent accession is set.

Georeferencing

No point is given. The plant was grown in a greenhouse at Bloomington, Indiana, so the page is a grow-out and its population's place is the seed's origin, which the label gives only as Thailand (Sakon Nokhon). That may name the province or its capital, the town of Sakon Nakhon; the province field carries the province. The herbarium's catalogue records the greenhouse as the locality and does not georeference the specimen. The map is off.

Dates

The collection date is left empty because the date the seed was gathered is unknown. The sample harvest date is the label's collection date, 12/7/95, which is 7 December 1995: the label writes dates month first, as the catalogue's reading of the same date (1995-12-07) shows. The germination date, 6/3/95, is therefore 3 June 1995.

Label reading

The sheet was read from the herbarium's photograph on 12 October 2026 (IND-0149681, 4,354 × 6,681 pixels). The typed label reads, line by line: Cannabis indica Lam. / Narrow-leaflet drug biotype / Country of origin: Thailand (Sakon Nokhon) / Seed source: HortaPharm B.V., Amsterdam, Holland / Source code: 91-170.22 / Parallel code: Th-2 / Greenhouse grown. Indiana Univ., Bloomington, IN / Used for morphometric analysis in 1995, rep. 4 / 312 cm tall, strong branching, vegetative stem aroma / Germ. date: 6/3/95; Collection date: 12/7/95 / K. W. Hillig Collection number: 00126.

  • The stamp reads 148943 (Herbarium of Indiana University), which the catalogue gives as the secondary catalogue number.
  • The plant is a pistillate branch with dense inflorescences. The label does not give the sex.
  • Sakon Nokhon is the label's spelling, quoted as written. The page uses Sakon Nakhon.
  • The catalogue names no determiner. The name in the infobox is the printed label's.


The infobox gives the maximum height as 3.12 m, the label's 312 cm tall on IND-0149681 converted to metres. The label's vegetative stem aroma names a characteristic but describes no scent, so the aroma field is left blank. The label's strong 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

Hillig's 2004 paper in Biochemical Systematics and Ecology (read) lists no accessions: for their codes and passport data it refers to his paper "Genetic evidence for speciation in Cannabis (Cannabaceae)", Genetic Resources and Crop Evolution 52 (2005): 161–180, which has not been read. So whether Th-2 was among the six Thai accessions the 2004 paper analysed is not established. Also not read: K. W. Hillig and P. G. Mahlberg, "A chemotaxonomic analysis of cannabinoid variation in Cannabis (Cannabaceae)", American Journal of Botany 91 (2004): 966–975 and Hillig's 2005 dissertation. The morphometric work named on the label (Used for morphometric analysis in 1995) has not been traced to a publication. Nothing on this page depends on these sources.
