Lysichiton americanus reported in the ‘Massif du Mont Pilat’ (France)
In a paper by Delaigue (2001) describing the first discovery in France of Tanacetum macrophyllum (Asteraceae – a non-invasive plant) in the ‘Massif du Mont Pilat’ (Massif Central), the presence of Lysichiton americanus (Araceae - EPPO Action List) is also mentioned. According to the EPPO Secretariat, this is the first documented record of L. americanus in France. In this paper, L. americanus is considered as an example of an exotic plant which has escaped from cultivation, but no reference is made to its potential invasive behaviour. The plant was observed in July 1999 in the “Haute Vallée du Furan” (Mont du Pilat, Massif Central). More data would be needed on the current situation of the population found in 1999, in particular to know whether it has expanded or not.
