SYSTEMATIC BoTANY 
By H. K. SvENson 
Astor Expedition Plants—Work on the collection of plants of 
the Astor Expedition to the Galapagos and Cocos Islands (1930) 
is practically completed. It is expected that the report will be 
published in the spring of 1933. 
Eleocharis —Progress is being made on monographic studies on 
the genus Eleocharis. Photographs of type-specimens have been 
received from several botanical institutions (Prague, Berlin, and 
Paris), and through the courtesy of the National Herbarium, 
Washington, and the California Academy of Sciences, San Fran- 
cisco, | have been able to study large representations of the genus 
from these institutions. Mr. C. C. Deam, State Forester of 
Indiana, and Mr. J. B. McFarlin, of the University of Michigan, 
have sent me extensive material from Indiana and Florida, re- 
spectively. A second contribution centering on the American 
species, Eleocharis capitata, was published as Brooklyn Botanic 
Garden Contributions, No. 65. 
GENETICS 
By Ratew C. BENEDICT 
Nephrolepis 
During the past year three lines of activity have been carried on 
with the Nephrolepis material. (1) The living plants have been 
maintained in their several divisions in the Experimental House 
No. 1, in a special exhibition set in House No. 3, and in the gen- 
eral collection in Houses No. 8 and 9. (2) A special collection of 
thirty plants was prepared and exhibited at the International 
Genetics Congress at Ithaca, August 24-31. (3) The photo- 
graphic material accumulated since the inception of this work at 
the Botanic Garden was assembled and reorganized and mounted 
in a special album with copious explanatory legends. 
was also exhibited at the Genetics Congress in Ithaca. 
Further, it may be noted that a set of about thirty varieties was 
sent to Prof. F. E. Lloyd, McGill University, Montreal, Canada.
