been done in comparing the lime-sink and lake regions.* The spe- 

 cies that are commoner in the western division are more charac- 

 teristic of drier or more calcareous or more phosphatic soils, and 

 nearly all of them grow in Georgia if not farther north; while 

 those commoner eastward are more characteristic of cypress ponds, 

 bays, scrub, and sour soils generally, and are of somewhat tropical 

 affinities, some of them being confined to Florida and others nearly 

 so. The former list includes more trees, vines, oaks, and legumi- 

 nous plants, and the latter more evergreens, pines, palms, and Eri- 

 caceae. In fact this plant list resembles that for the lake region 

 about as much as it does that for the western division of the flat- 

 woods. 



Fig. 28. Nearly treeless prairie in Brevard County about 7^ miles west 

 of Melbourne and four miles from the St. John's River, looking northwest. 

 The few scattered slash pines (Pinus Caribaea) are the outposts of the pine 

 forests which extend eastward to the Indian River. Between this point and 

 the St. John's River there are practically no trees. Feb. 5, 1915.
