It appears from the foregoing that the sparkleberry (Batodendron) is the 

 commonest Ericaceous plant in northern Florida, and that three others grow in 

 ten or more of the twenty regions. Kuhnistera pinnata is the only leguminous 

 plant listed from as many as ten regions, and 'nearly half the Leguminosae are 

 listed from only one region each.* 



It has already been shown in the statistical summary that regions 12 and 

 14 contain the largest quantity of Ericaceae, proportionately, and regions 14 and 

 17 the most Leguminosae. But statistics based on number of species, regardless 

 of relative abundance, naturally do not give exactly the same results. Regions 

 7 and ID seem to contain the most species of Ericaceae, and 12, 13 and 14 the 

 most species of Leguminosae. 



It is interesting to note that none of the Ericaceae are weeds, and none of 

 the Leguminosae are evergreen. 



*In the Altamaha Grit region of South Georgia, which corresponds to re- 

 gion 7 of this report, it has been estimated that the average Ericaceous plant 

 grows in 2.87 different habitats, and the average leguminous plant in 1.56. (See 

 Ann. N. Y. Acad. Sci. 17:326. 1906.)
