REPORT OF THE RESIDENT - INVEST IGATOR 
(FERNS) FOR 1941 
To THE DIRECTOR: 
I submit herewith my report for the year ending December 31, 
1941. 
A report of the year’s work on variation in the Boston Fern 
(Nephrolepis exaltata var. bostoniensis) and certain native fern 
species may be found on pages 104-105. 
Membership on the editorial staff of the American Fern Journal 
and on a special Membership Committee of the American Fern 
Society has involved a large amount of correspondence and con- 
ference relative to these two activities. In addition, during Dr. 
Svenson’s absence in South America, I was designated as ‘‘Act- 
ing Treasurer” of the Fern Society and served from the end of 
January until his return. 
By way of results, it may be noted that under Dr. W. R. 
Maxon’s work as editor-in-chief, the Fern Journal has completed 
its thirty-first volume with the largest pagination in its history. 
Furthermore, the back issues of the Journal, which were out of 
print or nearly so, have been re-issued, and the Fern Journal 1s 
now available in complete sets at the Botanic Garden. In the 
way of membership, the Fern Socicty has passed the four hund- 
red mark for the first time in its history.
