86 PHYSICAL GEOGRAPHY. 



Nebraska. Many trees of this species, near Ponca, are two feet in 

 diameter, and from forty to fifty feet high. On the Missouri bot- 

 tom, in the same section, they often grow in dense thickets. Is 

 found to the west line of the State in south Nebraska, and to the 

 102° meridian along the Niobrara and its tributaries. Also on the 

 Platte, in places, on the Elkhorn and the Loups. One of the 

 easiest of our trees to propagate. 



12. Red Bud. Judas Tree (Cercis Canadensis.) Common 

 along the Missouri bluffs. Occasionally on the Platte, Republican, 

 Elkhorn and Loup. Sometimes a shrub. 



13. Coffee-Tree (Gymnocladus Canadensis^) Nowhere abun- 

 dant. It is often met with in most of the larger timber belts of 

 the State. I have found it of larger size and more frequently in 

 Dixon and Dakota Counties than elsewhere in the State. I no- 

 ticed a few near the mouth of Fairfield Creek on the Niobrara. 



14. Honey Locust (Gleditschia triacanthos.) Common south 

 of the Platte, but rare north. A few on the Loup and on the Re- 

 publican. 



15. Water Locust (G. monosperma.) Rare in Nebraska. 

 Found only a few growing south of the Nemaha in Richardson 

 County. 



16. Wild Red Cherry {Prunus Pennsylvanica.) Southeastern 

 Nebraska. Saw the finest in Richardson County. Grows there 

 thirty feet high. 



17. Wild Black Cherry (P.serotina.) Southeastern Nebraska, 

 along the Missouri bluffs and on the Nemaha. 



18. Choke Cherry (P. Virginiana^) Common along the Mis- 

 souri bluffs, on the Republican, Nemaha, Niobrara and Loup. 

 Only occasionally reaches the dimensions of a tree; generally a 

 shrub. 



19. Scarlet Fruited r Y\\oxx\.{Cratcegus coccinea.) Tree small. 

 As frequently a shrub as tree. Widely spread over Nebraska 

 wherever there is timber, but nowhere abundant. In the form of 

 a tree it formerly could be frequently found along the Missouri 

 timbered bluffs, from the Omaha Agency to the north line of the 

 State. 



20. Black Thorn (C tomejttosa.) A low tree, but often a mere 

 shrub. It exists of tree size on the middle Niobrara. 



21. White Ash (Fraxinns Americana.) Grows in northeast 

 Nebraska to a magnificent size, and is comparatively abundant.
