12 FOREST-TREES OF THE UNITED STATES. 



The tree rarely exceeds 40 feet in height and 1 foot in diameter. It is 

 well worthy of cultivation. 



No. 83. Sophora affinis, T. & G. Texas and Southwest. 



No. 84. Sophora speciosa, Benth. Texas and. Southwest. Our twc 

 Sophoras are small trees of Texas and New Mexico, seldom over 6 inches 

 in diameter. They produce an abundance of showy flowers very early 

 in the season. The Sophora speciosa has evergreen leaves, and beautiful 

 red beans, which are said to be poisonous. 



No. 85. Gymnocladus Canadensis, Lam. Kentucky Coffee-tree. East 

 ern United States. A tall, large, and handsome tree, rare in Western 

 New York, Pennsylvania, and the States north of the Ohio River; more 

 common in Kentucky and southwestward. The wood is very compact 

 and close-grained, and valuable for cabinet-work. The large beans oi 

 the pods have been used for coffee. 



No. 86. Gleditschia triacanthos, L. Honey Locust. Eastern United 

 States. This is a large and handsome tree ; the trunk and branches 

 generally beset with long and formidable spines, on which account it has 

 been employed as a hedge-plant. The long pods contain a sweetish pulp, 

 and have been used in fermenting a kind of beer, but are of no practical 

 value. The wood is heavy, and affords excellent fuel, but is not consid- 

 ered durable as a timber. The tree is rare in the Atlantic States, but 

 rather common west of the Alleghanies,iu Tennessee, Kentucky, and the 

 tributaries of the Ohio and Mississippi. 



No. 87. Gleditschia monosperma, Walt. Water Locust. Illinois and 

 southward. This is a smaller tree than the preceding, growing in swamps 

 in the Southern States and in the vicinity of the Ohio River. The pods 

 are short, roundish, and only one-seeded. The tree is thorny, like the 

 Honey Locust. 



No. 88. Cercidiumfloridum, Benth. Green-bark. \v estern Texas and 

 Arizona. This is the Palo Verdi of the Mexicans and the Green-barked 

 Acacia of American travelers. The bark is smooth and green on the 

 young trees. It is a small, wide-spreading tree, with many branches, 

 rarely seen a foot through, and 20 to 30 feet high. 



No. 89. Parkinsonia aculeata, L. Jerusalem Thorn. Western Texas 

 and Arizona. Mostly a shrub ; quite ornamental, and frequent in culti- 

 vation in the region bordering on Mexico. 



No. 90. ParMnsonia microphylla, Torr. Western Texas and Arizona. 



No. 91. Cercis Canadensis, L. Redbud or Judas Tree. Eastern Uni- 

 ted States. The Redbuds are small trees; very ornamental. This spe- 

 cies is frequent east of the Mississippi. The next is found principally 

 on the Pacific coast. 



No. 92. Cercis occidentalis, Torr. Western Redbud. Western United 

 States. 



No. 93. Prosopis glandulosa, T. & G. Mesquit. Texas to California. 

 A scrubby, small tree, seldom more than 25 to 30 feet high ; sometimes 

 constituting extensive forests. It produces an abundance of bean-like 

 pods, which contain a sweet pulp. Both beans and pulp are eaten by 

 Indians and often by whites, but they are used chiefly as food for horses, 

 which eat them with avidity. The wood is very hard and durable, dark 

 brown, and resembles mahogany. Fences made of this timber are very 

 durable. The wounded bark in spring exudes a gum of the same quality 

 as gum arabic. 



No. 94. Strombocarpus pubescens, Gr. Screw-beau. Texas and west- 

 ward. This tree is very similar to the preceding, but of smaller size. 

 The pods are two to three inches long, and twisted like a screw. They
