32. The Willow-herb Group. 



Amongst the Willow-herb group or Onagraceae are 

 placed the exotic Fuchsias, which have become so 

 well acclimatised to this country that in the Isle of 

 Man, South and West of Ireland, Cornwall and the 

 Scilly Islands they grow in the open and attain the 

 size of hedgerow shrubs, being often used in gardens 

 for a fence. They are natives of Central and South 

 America, and New Zealand, or the Southern Hemi- 

 sphere. It is noteworthy that many plants of Great 

 Britain and other countries in the Northern Hemi- 

 sphere are found in the Southern Hemisphere, as in 

 New Zealand and the Falkland Islands, the two 

 zones of vegetation being largely similar in main types, 

 though less so in the component species. 



Save for this genus the Willow-herb group is 

 characteristic of the Northern Hemisphere. There 

 are about four hundred and seventy species and thirty- 

 six genera. 



These plants are mainly perennial. A few exotic 

 types are shrubs or trees. The Willow-herbs are 

 propagated vegetatively by stolons forming rosettes.
