Notes: The fruits of Geum urbanum have burrs, which are used for dispersal by getting caught in the fur of animals or clothes of people. Geum urbanum hybridises fairly regularly with Geum rivale (Water Avens), as they are closely related and occur together (Geum x intermedium). Geum urbanum is on the Belgium Red List of vascular plants classified as ´at the moment not threatened´. In the Sierra Nevada in southern Spain, apart from Geum urbanum three other Geum species can be found: Geum heterocarpum, Geum rivale and Geum sylvaticum.
