Named in honor of Mr.- W. T. Swingle, Director of the Sub- 
Tropical Laboratory at Eustis, to whom I wish to extend my 
thanks for the many favors shown me. His knowledge of the 
country and flora, which were freely imparted, enabled me to make 
much more valuable and extensive collections than would have 
otherwise been possible.
