habitat-groups, and scattered through the summaries. The 

 figures in the first column represent the percentage of the whole 

 area of the Altamaha Grit region supposed to be occupied by 

 each habitat ; and those in the second the percentage of the total 

 native flora included in each. Columns 3 to 5 show the relative 

 proportions of trees, shrubs, and herbs among the species of

vascular plants. (The three cases where these figures add up 

 more than 100 are where one species occurs both as a tree and 

 a shrub.) Columns 6 to 8 show the number of families, genera, 

 and species of vascular plants. Column 9 gives the percentage 

 of monocotyledons among the angiosperms, and the tenth and 

 last column the average duration of the flowering period, in 

 days. 



The accuracy of the figures for each group is of course approxi- 

 mately proportional to the number of species included. The 

 figures for flowering period are omitted in three cases where the
