332 BOTANICAL GAZETTE [NOVEMBER 
In Lower Florida wilds 
A volume by Srmpson,? described as a naturalist’s observations on the 
eology, geography, and life of the more tropical part of the state, presents 
much scientific information in an attractive popular manner, well illustrated 
with plates from good photographs. Two chapters should be of particular 
interest to plant ecologists, since the one outlines the plant succession from the 
pine lands to the ‘‘hammocks,”’ while the other gives a picture of the primeval 
forest of semitropical type. The author’s opinion that the broad level ever- 
green forest of the “hammock” is the true climax vegetation seems well 
founded, while his emphasis upon the destructive and retrogressive effect of 
fire appears to furnish a part, at least, of the explanation why such vegetation 
has not dominated a larger portion of the peninsula. 
The tale of the evolution of the land is attractively told, and seems as 
scientifically accurate as the story of the succession in the forests.—
