The appearance of Schimper's and Goebel's 



published works on the epiphytes created an interest 



in this group of plants among other Europeeui 



■botanists.Loew (15) studied the "epiphytes" inhabiting 



the willows of North Germany and found that fifty three 



percent of the "epiphytes" were brought to the tree by 



the agency of the wind due to the lightness of their 



seeds. Twenty three percent of the "epiphytes" originated 



from seeds brought by animals .The remainder of the 



"epiphytes" found their way to their supporting trees 



by unknown means .As a result of his study of the 



"epiphytes" he concludes that those plants which assume 



the epiphytic mode of life become associated with 



mycorhiza on the tree which they inhabit, This is merely 



£in assumption, for he presents no evidence in support 



of his view, He regards plants which are able to secure 



substances from humus by means of mycorhiza as better 



fitted to live as epiphytes than those v/hich do not 



have that ability.lt is probable that Loew's interest 



in this problem was inspired by Goebel's work rather 



than by Schimper's, 



Loew's view on the mycorhizal association in 



epiphytes was later disputed by other v/orkers. Willis 



that 

 and Burkill (32) pointed out a mycorhizal association 



is not necessary for epiphytic development. They found 



"epiphytes" occurring on the pollard willows near 



Cambridge, Englad, in old and fully decayed humus
