The writer continued his general curatorial duties in 
connection with the public exhibits and the study collections 
and devoted available time to monographic work on North 
American Flora. 
In continuation of the exploration of southern Florida, 
I visited for the most part either little-known or heretofore 
botanically unknown sections, both on the mainland and 
on the reef. An account of one trip was published in the 
Journal for November, and a report on the rest of the work 
is in preparation. In connection with the exploration 
referred to, two special collecting trips for cacti were made 
into northern Florida and into eastern South Carolina. As 
a culmination of some of our special investigations in 
southern Florida, a short history of Royal Palm Hammock 
was written and printed in the Journal for October. This 
aper was used in connection with the public dedicatory 
exercises of Royal Palm State Park in November. 
Respectfully submitted, 
. K. SMatt, 
Head Curator of the Museums and Herbarium.
