Tilia for "Basswood", Pinus for "Pine", Rosa for "Rose", Fragaria for 

 "Strawberry", Castanea for "Chestnut", and Falcata for "Hog Pea-nut",, 

 etc.? 



It is understood in the classification of plants that genera are 

 groups of species, and that genera in turn constitute families, while 

 families are grouped into orders, orders into classes, and finally a series 

 of classes constitutes a phylum. Phyla are the principal groups of the 

 plant world, such as those including the ferns, the mosses, the pond 

 scums, and the flowering plants. This system for the classification of 

 plants has been found possible because botanists have discovered relation- 

 ships among plants, and these different groups are employed to indicate 

 the degree of such relationships. So I have given the scientific names 

 of all of the trees discussed in this little book and have also indicated 

 the families to which the various species belong. The family name of a 

 plant can be told by the ending of the word, -aceae, as Rosaceae, the rose 

 family, or Pinaceae, the pine family. I have also given a "common" 

 name or two for each species, but the uncertainty and often the utter 

 meaninglessness of such names must be understood. 



NUMBER OF NEBRASKA TREES 



There are approximately sixty different species of native trees 

 in Nebraska. We cannot say exactly how many there are because it is 

 often difficult to decide as to whether a given woody plant is a tree 

 or a shrub, unless we adopt some rigid, arbitrary definition for these 

 two types of growth, and even then we would experience some uncer- 

 tainties. Some botanists would place certain species in one group and 

 others would probably place the same species in the other group. How- 

 ever, there are about sixty species of woody plants growing naturally 

 in this state which most botanists would readily class as trees. 



Certain woody plants which occasionally develop into the form 

 cf large shrubs or small trees, and therefore might possibly be in- 

 cluded in our list of trees are as follows: 



Acer glabrum, Mountain Maple. 

 Cornus candidissbna, Cornel or Dogwood. 

 • Euonymus atropurpareus, Burning-bush or Wahoo. 

 Lepargyraea argentea, Buffalo Berry. 

 Prunus melanocarpa, Choke-cherry. 

 Rhamnus caroliniana, Indian Cherry. 

 Rhamnns lanceolata, Common Buckthorn. 

 Rhus copallina, Sumac. 

 Rhus glabra, Smooth Sumac. 

 Salix bebbiana, Bebb's Willow. 

 Salix lucida, Shining Willow. 

 Salix missouriensis, Diamond Willow.
