BOTANICAL DESCRIPTIONS 
The following plant analysis is in six divisions, viz. : 
Native and naturalized trees. 
Native and naturalized shrubs. 
Native and naturalized vines. 
Foreign and extra-limital trees. 
Foreign and extra-limital shrubs. 
Foreign and extra-limital vines. 
After each section in the description are the respective 
leaf-illustrations, showing every leaf whose form is suffi- 
ciently characteristic to aid materially in identification. 
Actual size is not given, this being unnecessary ; only 
the outline and system of venation (the way in which the 
veins are arranged), the latter being often very distinc- 
tive. The further details are found under each leaf’s 
proper number, which is given at the bottom of each 
plate. The fractions, (34), (%), etc., following the 
proper numbers, mean that the illustrations are one-half, 
two-thirds, etc., of the average size of the leaves. Only 
the single leaf (simple or compound) is illustrated, except 
in case of two or more forms on the same plant, or 
when the mode of growth on the stem is to be shown. 
In the Analytical Keys the plants are represented by 
their proper numbers. 
To assist those who wish to learn our trees, shrubs, 
and vines, but have never studied botany, a brief ac-
