Table P presents an analysis of the Dicotyledonous floras of various 
legions of the frigid, temperate, and tropical zones. The first column 
of figures on the left gives the total number of Dicotyledons, exclusive 
of aquatic, parasitic, and leafless forms, in the flora of each region. 
The three succeeding columns record the percentages of trees, shrubs 
(all ligneous forms except arborescent species) and herbs that occur 
in these floras; and in the last three columns are tabulated the per- 
centages of the trees, of the shrubs, and of the herbs that have leaves 
or leaflets with entire margins.
