Evidentiary scope

The article rests on the RSC listing for Malawi Gold, the Kwik Seeds listing of the same line and RSC's Heirlooms category page. Kwik Seeds is the shop RSC calls its other site (RSC, Hemp & Multipurpose). The listings give the sourcing as Afropips, via the collector community, and date the original collection only as "several decades ago". They name no collection site, collector or farmer, and place the variety at Nkhotakota through the genetics line rather than through a documented collection. The account of Afropips, of Jim and of the Malberry cross is RSC's and has not been checked against other sources; the article attributes it. The description quoted from Afropips is quoted as RSC quotes it. Éloise 03:55, 18 September 2026 (+07)

Georeferencing

The listings name Nkhotakota in the genetics line and as the region the best Malawi landraces are associated with, and give a latitude of about 13° S. So that the accession appears on the map, the coordinate is the midpoint of Nkhotakota district's extent along 13.00° S in OpenStreetMap (relation 7343221, full polygon; 33.93° E to 34.33° E), rounded to two decimal places: −13.00, 34.13. OpenStreetMap places the point inside that district. It is an inference from the listings, not a collection site. Éloise 03:55, 18 September 2026 (+07)

Editorial treatment

• Accession ID. RSC-MWI-CEN-0120190001 uses MWI, the ISO 3166-1 code for Malawi, and CEN from the Central Region, which contains Nkhotakota district. The month digits are 01.
• Year. The listings never date the collection. The ID and the descriptive name use 2019, the first year in which the listing is attested with this seed, its earliest archived version being 19 August 2019. The collection date field is left blank. Ruled on 17 September 2026: the first attested year stands, which is what the batch does wherever a collection year is missing. A collection year found later means a page move.
• Province. Central Region, Malawi's first-level unit, which contains Nkhotakota district, entered with its type word as Madagascar's Diana Region and Anosy Region are. A qualified title such as "Central Region, Malawi" cannot be entered here, because the infobox splits a comma in this field into two links, which would mint a bare Central Region link and a stray Malawi one. The name is ambiguous across countries, so the page may need a qualified title and a move later; that is Éloïse's call.
• Name and type. Malawi Gold 2019 IBL, with classification Landrace IBL, accession type Reproduction and sourcing type Multi-generation reproduction, as on the Cretan and Arcadian heirlooms, from "an IBL of a classic tropical Sativa landrace", "maintained ex-situ for decades" and "reproduced from seeds kindly donated".
• Collector. Left blank: the listings name Afropips and a collector community, not a collector.
• Flowering time. 14 to 16 weeks, the indoor range RSC gives.
• Height. 2 to 4 m, the union of RSC's "up to 4 metres" and the 2 to 4 metres that Kwik Seeds and the RSC listing until July 2024 give.
• Photoperiod. Short-day, the corpus convention; RSC states only that the variety requires a tropical light cycle outdoors.
• Conservation priority. Low: an inbred line maintained ex situ for decades and circulated through the collector community, as on Arcadian, the other ex situ heirloom with a rating. RSC's own description of the line as increasingly rare is about pristine heirlooms in general. The ratings follow the accession definitions in authored/planning/DESIGN.md: Critical rare, from a single farmer or micro-population; High limited population, few sources; Medium moderate population, multiple sources known; Low common, broadly available within its range.
• Lineage. RSC describes a line descended from seed collected in Malawi several decades ago and maintained ex situ for decades by Jim of Afropips, and calls it an IBL and a heirloom; the description read "reproduced from seeds kindly donated" from August 2019 to July 2024 and "maintained ex-situ" with the Malberry F1 from December 2024. The lineage convention staged in authored/tasks/Accession_Lineage_2026-09-17/ treats a collection and a reproduction of it as separate accessions. There is nothing to separate here: the listings neither date nor place the original collection beyond Malawi, so no accession for it can be written, and the holder of this line is Afropips rather than the collector. The wording is recorded so the lineage pass can check it.
• Not entered. Chemotype, because the THCV attribution is Afropips' and gives no ratio; culling and selection type, because the listings describe no selection method.
• Links. Malawi, Nkhotakota District and the Central Region are linked as committed future pages. Afropips, Jim, Malberry, Blueberry, Skunk and Northern Lights are left unlinked, as suppliers and hybrid names are in the other batches.
• Conventions. Photoperiod Short-day and introgression Minimal follow the other RSC accessions; neither listing states them. Éloise 03:55, 18 September 2026 (+07)

Source discrepancies

• Purpose. RSC: "Ganja (bud)". Kwik Seeds: "Ganja (seedless or semi-seeded flowering tops)", RSC's line in 2019.
• Lead. RSC: "an IBL of a classic tropical Sativa landrace". Kwik Seeds: "collected in Malawi several decades ago and reproduced from seeds kindly donated by a landrace collector", RSC's line from August 2020 to July 2024.
• Height. RSC: "Up to 4 metres". Kwik Seeds: "2 – 4 metres outdoors", RSC's figure until July 2024.
• Characteristics. Kwik Seeds keeps "Long-flowering", which RSC dropped after 2019.
• Only on RSC. Jim of Afropips, the Malberry cross, the note that the line has never been outcrossed, the tropical light cycle and the indoor flowering times.

The listings do not explain the differences. The article uses both and attributes each. Éloise 03:55, 18 September 2026 (+07)

Archived versions

The Wayback Machine holds 25 versions of the RSC listing, from August 2019 to April 2026, and all were read. No version dates the collection, and all describe the same Afropips line, so all of them describe this accession.

• Sourcing. "Afropips, via community" in August 2019 and "Afropips, via collector community" since October 2019.
• Lead. "Reproduced from seeds kindly donated by a landrace collector" from August 2019 to July 2024; "collected in Malawi several decades ago" added in August 2020; the present lead, with Jim of Afropips and the Malberry cross, from December 2024; "an IBL of a classic tropical Sativa landrace" from August 2025.
• Height. "2 – 4 metres" until July 2024 and "Up to 4 metres" from December 2024. The article cites the version of 5 August 2020.
• Classification. "C. sativa subsp. indica var. indica" from August 2020 to March 2025. The article cites the versions of 5 August 2020 and 26 March 2025.
• Growing notes. The tropical light cycle and the indoor flowering times first appear in August 2025.
• Photographs. The Afropips photograph has been on the listing since August 2019 and the Malawi cob since August 2020; the 2019 versions captioned both (see below). The three field photographs first appear in December 2024, with the note that they show plants from this accession at 40° N in mid-July. Éloise 03:55, 18 September 2026 (+07)

Photographs

The infobox image and the gallery are the five photographs on the RSC listing, uploaded under fair use at reduced resolution. RSC states that "The field shots show plants from this accession at 40° N in mid July" and that "The historic photo shows a Malawi cob from the 1980s", so those captions follow the listing; the field photographs have a face masked out. The August to December 2019 versions (Wayback Machine) captioned two photographs, hosted on kwikseeds.com and the same images as the files the listing shows now: the flower top as Afropips' photograph of its Malawi landrace, whose leaflets RSC says show stress from overwatering or overfeeding, and the cob as a Malawi cob of the 1980s. The field photographs first appear in December 2024. Éloise 03:55, 18 September 2026 (+07)
