88 PRACTICAL FORESTRY. 



description of the trees mentioned in these pages, can 

 find it in various botanical works published in this 

 country and Europe. 



Shrubs that seldom reach the hight of twenty feet are 

 omitted, except in some instances where they belong to 

 a genera containing trees of larger growth, and in such 

 instances they will be mentioned briefly. I have ar- 

 ranged the list of trees alphabetically according to their 

 generic name, and while this is not in accordance with 

 the botanical classification, it will be found just as con- 

 venient for all practical purposes. I make only two 

 classes, the first comprises the deciduous trees and broad- 

 leaved evergreens which are principally indigenous to 

 the Southern States, and the second the conifers or 

 cone-bearing trees, the greater part being evergreens. 

 There are a few like the Larches, Taxodiums, and Salis- 

 burias that are deciduous trees, but they belong among 

 the true conifers. 



ACACIA GREGGII, Gray. 



A small tree, but sometimes over twenty feet high. Leaves 

 small, short, composed of two or three pairs of pinnae an inch 

 long, and leaflets of four or five pairs, oblong or oblong-ovate. 

 Flowers in cylindical spikes an inch or two long, succeeded by 

 curved pods three or four inches long. Seed about a half inch 

 long. Branches either naked or armed with stout-hooked 

 prickles. Wood firm and hard, but usually too small to be of 

 much value. Native of Texas and westward to Southern Cal- 

 ifornia. There are quite a number of the species of the 

 Acacia that have been introduced from tropical countries, and 

 are now naturalized in the Southern States, also a much larger 

 number that are cultivated as green-house plants. 



ACER. Maple. 



An extensive genus, containing some fifty species, mostly of 

 the northern hemisphere, and pretty evenly distributed through 

 the northern border of the temperate zone in America, Europe, 

 Asia, and Japan. There are nine or ten species, natives of the 

 United States, more than half of which are valuable timber
