Coincya monensis subsp. monensis
subspecies of plant
Coincya monensis subsp. monensis, the Isle of Man cabbage, is a species of plant in the family Brassicaceae that is found in coastal habitats on the west of the island of Great Britain (from north Devon to Kintyre) and around the coasts of the Isle of Man.
Conservation status
The subspecies is thought to naturally occur in only 22 localities and is endemic to the British Isles. It is listed as a nationally scarce British species and is in serious risk of extinction. The species was once abundant on the Isle of Man, hence its name, however, for an unknown reason its population has collapsed to only a few individual and isolated plants. On the Isle of Man, the Manx Wildlife Trust began propagating the species in their greenhouses in 2006. It is hoped that this will halt the decline of the species and prevent its extinction. In 2022 it was added to the Isle of Man’s red-list of plants of conservation concern.
Habitat
The plant prefers light (sandy), medium (loamy) and heavy (clay) soils, which must be well-drained yet moist. The plant can grow in acidic, neutral and alkaline soils, in semi-shade (light woodland) or no shade.
Begin with the source’s own compact description: “Coincya monensis subsp. monensis” is subspecies of plant. The dossier treats that line as a proposition to test through Coincya, monensis and subsp, not as a finished interpretation.
Why this record matters
The phrase “subspecies of plant” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Apr 21, 2026. The linked authority identifier is Q5141590. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2006 and 2022.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
