The Ferns of Washington 



t. c. frye and mabel mcmurry jackson" 



Introduction 



This work was begun in the fall of 1909, at the opening 

 of Mrs. Jackson's senior year at the University of Wash- 

 ington. The drawings are original and the descriptions 

 were checked with the plants. Nothing new is claimed 

 for the work, but it is hoped that it will enable even 

 those who know very little about botany to recognize 

 the ferns of our State with certainty. The division of 

 the labor was as follows: 



Mabel McMurry Jackson — All drawings except one; 



the writing of the first draft of the keys and descriptions. 



T. C. Frye — Revision of the keys and descriptions; 

 origin of generic names; uses of the plants. 



S. M. Zeller — The photographs. 



Bess Cowley — One drawing of Adiantum. 



y iterial of several species was furnished by Mr. W. 

 N. Suksdorf and Mr. John B. Flett.
