GEOGRAPHY OF CENTRAL FLORIDA

swamp, and loamy sand. Scrnl), or white sand, under the various 

 designations of "Norfolk sand with scrub oak vegetation," "Leon 

 fine sand, scrub phase," "St. Lucie sand," and "Leon fine sand, 

 rolling phase," makes up about 2% of the total. A few mechanica? 

 analyses are given in the general chapter on soils, but no relialjle 

 chemical analyses seem to be available yet. 



Vegetation. High pine land, with or without a lower story of 

 black-jack or turkey oak or both, makes up at least three-fourths of 

 the total native vegetation. (See figs. 9, I'o.) The oaks seem to 

 increase, in numbers wherever the pines are cut off, perhaps chiefly 

 because that allows the ground to dry out a little more and they 

 prefer the driest soils. There are a good many hammocks, mostly 

 along rivers and on lake peninsulas and islands, and a few patches 

 of scrub (fig. 11), ranging in size from a few acres to several 

 square miles. 



As there is more high pine land than all other vegetation com- 

 bined, a census of plants, especially herbs, for the whole region 

 bears considerable resemblance to that for high pine land in the 

 "Ocala area," published in the 7th Annual Report (pages 166-167). 

 The commonest species seem to be as follows, except that herbs 

 that bloom in late summer and fall are probably not represented 

 as well as they should be, for lack of observations at that time of 

 year. The first tree listed is, or was originally, probably at least 

 fifty times as abundant as its nearest competitor.
