Perhaps no British Fern is so universally admired as the 

 'Oak Fern.' Its rapid and elegant growth, and the vivid green 

 of its fronds render it a charming addition to our hardy Fernery. 



It is a native of England, Scotland, Wales, Ireland, Lapland, 

 Sweden, Russia, North Cape, Germany, Hungary, Croatia, 

 France, Switzerland, Italy, Spain, Siberia, Gibraltar, Kamt- 

 schatka, Asia, Africa, Labrador, Greenland, Newfoundland, 

 United States of North America, the Rocky Mountains, Columbia 

 River, etc. It has thus a very extensive geographical range. 

 Singular enough it has not been found in Greece or Turkey.
