258 FLORIDA GEOLOGICAL SURVEY SIXTH ANNUAL REPORT. 



the average of the three percentages, on account of the difference in 

 size of the three divisions. For the same reason the order of 

 abundance is not exactly the same as that of the sums of the per- 

 centages). Thus in the case of a species preceded by a + mark 

 some one, or occasionally even two, of the percentages may fall be- 

 low the average of that species for northern Florida ; and vice ver- 

 sa. Where two + marks are used the highest figure of course in- 

 dicates the division in which the species is more abundant than it is 

 anywhere else; and in the other two divisions it may possibly be 

 below the northern Florida average.
