470 pages, 462 illustrations, 8vo, cloth; postpaid $4.22 
This work is a revised and enlarged edition of the book 
brought out by Professors Coulter and Chamberlain in 1go1. 
Each of the seven great groups is here presented in detail, 
and a final chapter discusses the problem of phylogeny and points 
out the evolutionary tendencies. The extinct groups, notably 
the primitive ‘“‘seed-ferns,’’ are now included for the first time; 
and vascular anatomy is fully recognized as a morphological 
subject of first importance. The entire presentation is thoroughly 
and systematically organized and arranged with a view to the 
greatest possible clearness. The illustrations are numerous and 
in large part original.
