ARCTIC PLANTS NOT YET FOUND IN BRITAIN 



35 



Gentiana aurea L., G. tenella Rottb., Pediciilaris lapponica L., Veronica longifolia L., 

 Pinguicula villosa L., Galium trifidum L., G. triflorum Michx., Petasites frigidus (L.) 

 Fries, and Taraxacum lapponicum Kihim. Of all the accepted native arctic species not yet 

 found in Britain, these are the 50 whose continental European (especially Scandinavian) 

 ranges, v/ith some other considerations, seem to allow them the best chance of occurring 

 in the British Isles. What a delightful holiday sport to hunt for them in the' lesser-known 

 parts of Scotland or the accompanying isles !
