After reading this Leaflet, if one is interested enough to 
read a more extended popular account, either D. H. Scott’s 
‘‘The Evolution of Plants” or Seward’s ‘‘Links with the Past in 
the Plant World” will be found very entertaining. ‘‘Hypothetical 
ancestral trees” have a tendency to promote dogmatism in the 
casual reader, but, if one is interested, several of the latest, em- 
bodying the views of America’s most eminent authorities, may 
be found in chapters 36-38, C. S. Gager’s ‘‘ Fundamentals of 
Botany.” ‘‘Outlines of Geological History,” by Willis and 
Salisbury, and ‘‘The Evolution of the Earth and Its Inhab- 
itants,” edited by R. S. Lull, will interest those more profoundly 
inclined. There are other ways, of course, than those of study- 
ing the fossil record by which one may investigate the evolution 
of plants, but the latter probably gives the most accurate data.
