This is an opportunity for attendees to familiarise themselves with some of the rapidly increasing community of Mediterranean ecosystem plants that are establishing in our cities. Species such as Sisymbrium irio (London-rocket), Polycarpon tetraphyllum (Four-leaved Allseed), Urtica membranacea (Mediterranean Nettle) and Laphangium [Gnaphalium] luteoalbum (Jersey Cudweed) are locally frequent. Other, more unusual species such as Genista aetenensis (Mount Aeta Broom), Eriobotrya japonica (Loquat), Calocedrus decurrens (Californian Incense-cedar) and Persea americana (Avocado) will also be seen. This meeting is suitable for beginners and for more experienced botanists. Please bring a packed lunch.

Meet at 11:00am outside the entrance of Farringdon Underground, Cowcross Street, Clerkenwell (TQ31598183).
