404 PENNELL: STUDIES IN THE AGALINANAE 
Florida. Distribution notes are made as definite as practicable.* 
All localities from which specimens have been seen are listed, and 
in the case of specimens of my own collecting numbers are given. 
Of course many specimens have been seen with data too vague 
for such classification. In the fuller revision of this group upon 
which the writer is working it is intended more fully to index 
specimens seen. 
In prosecuting this study I have been most deeply indebted 
to the following three gentlemen: to Mr. Roberts Le Boutillier, 
of Wayne, Pa., whose generosity enabled me to accomplish the 
field-work required, to Dr. Roland M. Harper whose knowledge 
of the flora of the Southeast, most generously imparted, has made 
my search far more successful than it otherwise could have been, 
and to Dr. John M. Macfarlane, under whose direction and con- 
stant support this study has been made.
