Welcome Autumn with ... 
A FIELD GUIDE TO WILDFLOWERS 
of Northeastern and North-Central North America 
by ROGER TORY PETERSON 
and MARGARET McKENNY 
The Peterson Field Guide system, which revolutionized the identi- 
fication of species, has now been brought to bear on wildflowers. 
Unlike conventional botanies, arranged in the traditional order of 
plant relationships, this “Field Guide” provides shortcuts to identi- 
fication that makes it easy to recognize flowers by sight. 
Almost 1300 species of herbaceous plants are represented. Im- 
mediate reference is by color. The family to which each belongs 
is recognized at a glance by means of a symbol. At the front of the 
book each symbol is linked to a brief nontechnical description of 
each of the 84 families included. 1334 illustrations; 23 color plates. 
— Price $4.95, plus 50c for sales tax & postage — 
“Librarians have been poised to order this invaluable addition to 
the ‘Field Guide’ series ... The ‘Wildflowers’ identification system 
makes things very easy for the laymen—it’s by color, though families 
of flowers are also described. The book is divided into six main 
sections, tabbed with color corners ... Peterson’s books and his 
identification systems for birds are known over the world. Margaret 
McKenny, a native of the State of Washington, is an author of several 
books, photographer, and lecturer. Expect orders to pour in for 
this.” —’’Publishers’ Weekly”
