Registered but not published
Sanko holds further sources that do not meet its export conditions. They are listed here because an omission that nobody can see is not a provenance claim.
| Source | Status | Why it is excluded |
|---|---|---|
| Sanko plant_lookup_v1 legacy mappings | legacy_unverified | Original citations, language labels, and collection locations were not retained in the flat runtime file. These mappings remain available for backwards compatibility but require source review. |
| Which Plants for What Ailments: A Quantitative Analysis of Medicinal Ethnobotany of Ile-Ife, Osun State, Southwestern Nigeria | quarantined | The published tables are retained in surveys/quarantine for auditability, but excluded from all generated mappings because the publisher retracted the article. |
| Ethnobotanical uses of plants in Nigeria: an analysis of current research trends and patterns | discovery_only | Table 2 is retained as a catalogue of 79 original studies to acquire. Table 3 is retained as secondary review evidence only and cannot produce runtime mappings. |
| Medicinal Plants in Tropical West Africa | reference_only | Retained for botanical, synonym, pharmacology, and bibliographic checking. The book does not provide a structured language-labelled vernacular index, so no local-name mappings were inferred from its prose. |
| Handbook of African Medicinal Plants, Second Edition | staged_review | Only concise mapping facts and page locators are staged. Runtime export is blocked because most vernacular labels lack a row-specific country or locality and have not been reviewed by language practitioners. |
| Europe PMC and Crossref primary-source discovery | discovery_only | Written by scripts/discover-sources.js. A ranked list of Nigerian ethnobotanical sources to acquire, and the resolution of the 79 original studies catalogued in anumudu-2025-nigeria-review to DOIs, licences and full texts. Candidates are citations, not data: no row here produces a vernacular mapping, and an acquired source only becomes ingestable when it is registered in this file in its own right. |
| Wikidata taxon labels in Nigerian languages | discovery_only | Written by scripts/import-wikidata-vernaculars.js. Labels are crowd-sourced and unsourced — no locality, no collector, no citation — and a large share of those returned in an African language are the botanical or English name filed in the wrong language. They are candidates for review, never mappings. A candidate reaches the runtime index only through practitioner confirmation, attributed to the reviewer who confirmed it and carrying the candidate source it came from. |
