Area: A very common and variable plant with numerous varieties which 
in a later time shall probably partly at least prove as well defined species. It 
grows in forests on mountains from the Concan to Ceylon and from the Khasia 
Mountains to Tenasserim; I found it also among the collections from German 
New Guinea.
