124 FLORIDA GEOLOGICAL SURVEY I3TH ANNUAL REPORT 



an estimate of its area, for the region has scarcely been touched b}i 

 soil surveys yet.* In Marion County, northeast of Silver Springs, 

 are some clayey flatwoods, of unknown extent, which probably 

 belong to this region. The occurrence of marl and peat in low 

 places has been mentioned above under the head of geology. Some 

 of the low hammocks seem to contain gypsum deposits, as in the 

 Gulf hammock region. 



Vegetation. The prevailing vegetation type on the uplands js 

 high pine land, very similar to that in the lime-sink region. (Fig. 19, 

 tliough intended for a different purpose, shows it pretty well). 

 Scrub (fig. 38) occurs in 'all sorts of situations topographically; 

 usually not far from lakes, but often on uplands remote from any 

 body of water. The level flatwoods bear the vegetation character- 

 istic of such places, and peat prairies and saw-grass marshes border 

 the larger lakes or completely fill small basins. Sandy shores of 

 lakes have cjuite a characteristic growth of sedges and other con?- 

 paratively small and wiry plants (as do similar places in New Eng- 

 land), merging gradually into that of peat prairies in many places. 

 Peninsulas jutting out into lakes are commonly occupied by sandy 

 hammocks, and marly low places by low hammocks, much like those 

 in the Gulf hammock region. Small and non-calcareous streams 

 are usually bordered by non-alluvial swamps or bays, containing a 

 large portion of evergreens. 



The commonest plants in the lake region seem to be as follows :
