Pteris multifida

Pteris multifida Poiret (E-As.) – A very rare garden escape, known at least since 2001 from the basement (ruins) of the former Military Hospital in Berchem (Antwerpen). Here well established and more or less naturalised. From 2005 onwards found on several nearby basement walls (Zurenborg-quarter). Similar records from neighbouring countries are available for the British Isles (Edgington 2006, Crouch & Rumsey 2007), Germany (Radkowitsch 2008) and the Netherlands (Verloove & al. 2007).
