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, will interest those more technically inclined. There 
are other ways, of course, than those of studying the fossil record 
by which one may investigate the evolution of plants, but the 
latter probably gives the most accurate data.
