ADIANTUM (Maidenhair) is one of the most important genera 

 of ferns, as it contains several of our most popular decorative plants. 

 There are nearly a hundred known species; many of these are in 

 cultivation, besides numerous varieties and forms. There is great 

 diversity of form in the fronds of different species. A. renijorme is 

 simple and kidney shaped. Among others A. macro phyllum and 

 A. perimianum have the fronds simply pinnate. In the greater 

 number of species the fronds are much branched. Where large col- 

 lections of ferns are grown it would be a difficult task to select the 

 most beautiful and interesting kinds, as this genus above all others 

 does not possess a single species but what is worthy of a place in
