76 ALIEN FLORA OF BRITAIN 



[Ribes alpinum, L. Doubtless native in Northern 

 England, but in its numerous other Scotch and English 

 stations an escape from garden culture.] 



[Ribes Grossiilaria, L. An undoubted native of 

 most of Europe, reaching the northern shores of the 

 Continent. It is doubtless also indigenous in England^ 

 but the extensive cultivation of the gooseberry and the 

 readiness with which it can be bird-sown has thrown 

 doubt upon it in many localities. There is nothing 

 in the geographical range of the species to make its 

 nativity improbable, and it is common in damp woods 

 in perfectly natural surroundings in England, just as it 

 is throughout the rest of its range.] 



[Ribes nigrum, L. This species grows in Britain 

 and the greater part of the rest of Europe under 

 exactly the same circumstances as Ribes Grossularia^ 

 and should probably be admitted as a native for 

 similar reasons. It seems inadmissible to suppose that 

 a species growing here amid natural surroundings^ 

 independently of cultivation, and native on the adjacent 

 parts of the Continent, is not a native. It appears 

 strange that British botanists, with a few exceptions^ 

 have excluded the species from the British Flora.] 



[Ribes rubrum, L. A native of England and the rest 

 of Northern Europe, growing in similar situations 

 to the last two, and for the same reasons admitted 

 as indigenous. It has been frequently classed as an 

 introduction by local botanists, but less often so than 

 the last-named species.] 



[Saxifraga Geum, L. Native of Western Europe,.
