There are fewer disc florets than in Nodding Bur-Marigold, but these too have dark stripes on them. Note the tiny barbs on the disc florets, but most Bur-Marigolds have this feature.


Not to be semantically confused with : Branched Bur-Reed or Un-branched Bur-Reed nor with Burdocks such as Lesser Burdock (Arctium minus) nor with any of the Burnets such as Great Burnet (Sanguisorba officinalis) nor Bur Chervil (Anthriscus caucalis) or Pirri-pirri-bur (Acaena novae-zelandiae) [plants with similar names from different families]

No relation to : Branched Bur-Reed nor with Un-branched Bur-Reed. And although they are in the Same Daisy Family, neither are they related to Marigolds such as Common Marigold which is in a differing Genus. [plants with similar names]. [plants with similar names].

This is much less widespread than is Nodding Bur-Marigold but neither are ubiquitous. London Bur-Marigold has a presence on the Grand Union canal, and spread northwards up the canal from London. It is not found elsewhere.
