(and about 17 others seen only once) 
About half the woody plants of this list are evergreen. There 
is only one representative of the Ericaceae, Vactinium nitidum, and 
the Leguminosae seem to be entirely absent. The vegetation bears 
considerable resemblance to that in and around small lakes in the 
lake region,f but it includes also a few species believed to be lime- 
loving, most of them, however, too rare to be listed above. 
About the only use made of this vegetation is as pasturage, for 
which it serves very well. 
2. SCRUB THICKETS. 
(figure 59.) 
Some of the prairie areas pass abruptly at their edges into high 
or low pine land, and some are bordered by hammocks. Many of 
the arms of Lake Tsala Apopka have a narrow fringe of evergreen 
shrubs, consisting mostly of the following species : Ilex glabra (gall- 
berry), Pieris nit id a, Bejaria racemosa, and Pycnothymus rigidus. 
On some of the peninsulas of the same lake this fringe passes 
into a more extensive type of vegetation, covering several acres, 
which might be called scrub thicket, for want of a better name. It 
consists mostly of evergreen shrubs and small trees from five to ten 
feet in height, with no tall trees and few herbs. The soil is sandy 
and sterile, but contains a few burrows of some animal about two 
inches thick which has not been seen or identified. Fire is in¬ 
frequent.
