* Orders represented by the same number of species in the Flora of the World, in the Australian Flora, or 
in the Mexican Flora are indicated numerically as occupying the same position in the sequence, otherwise 
some of them would be removed a considerable distance from their true positions ; and in comparisons the same 
course should be taken with the Indian orders of equal representation, here bracketed.
