* This Synopsis is designed, not only to exhibit the Linnaean arrangement, but 
also to serve as an artificial key to the genera, which, at the outset, the student will 
occasionally need. To render it sufficient for this purpose, the genera are repeated 
under different classes and orders, when the species vary in respect to these techni¬ 
cal characters, or might be referred with about equal correctness to either of two or 
thfee"classes, as Asclepias, Lobelia, &c. A Conspectus of the Classes, with their 
characters, is given on the opposite page. The numbers at the end of the lines re¬ 
fer to the page where the genera stands In the body of the work.
