 are often propagated by suckers, which, are thrown up in large 

 quantities, or by seeds. 



C. humilis is a valuable and highly decorative European 

 species, very largely grown. It presents a very attractive sight 

 as an isolated plant in sub-tropical gardens. Trie stem, which is 

 straight, is covered with rough fibres, and also by the base of
