GEOGRAPI1Y OF CENTRAL FLORIDA 99'

 swamp, and loamy sand. Scrub, 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 mechanical analyses are given in the general chapter on soils, but no reliable 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, ro.) 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. ii), ranging in size from a few acres to several square miles.
 As there is more high pine land than all other vegetation combined, 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.
