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 leafs 

 proper number, which is given at the bottom of each 

 plate. The fractions, ()^), (/^), 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-
