CHECK LIST OF FOREST TEEES 51 



Juglans rupestris major Torrey. Nogal. 



Range. — Texas (Tarrant County) ; southern New Mexico and Arizona; also 

 in central Arizona (Oak Creek — 30 miles south of Flagstaff). 



NAME IN USE 



No gal 



Juglans californica S. Watson. 20 California Walnut. 



Range. — Southern California coast region (from Santa Barbara to the San 

 Bernardino Mountains). 



NAMES IN USE 



Walnut (Calif.). California Black Walnut (lit.). 



California Walnut (Calif.). 



Juglans hindsii (Jepson) Render. Hinds Walnut. 



Range. — Central California coast region. 



Note on nomenclature. — Formerly designated in part, as Juglans californica 

 S. Watson, and recently as Juglans californica var. Hindsii Jepson. In raising 

 the third term of the latter trinomial to specific rank the author of the resulting 

 binomial (Juglans Hindsii) would seem to have violated a rule of the Interna- 

 tional Code of Nomenclature. The spirit of the American Code would, however, 

 permit doing this. 



NAME IN USE 



Hinds Walnut 

 HICORIA Rafinesque 



* Hicoria pecan (Marshall) Britton. Pecan. 



Range. — Iowa (Mississippi River, in Muscatine and Clinton Counties) 

 through southern Illinois and Indiana, western Kentucky and Tennessee to 

 central Alabama and Mississippi, through Missouri and Arkansas to southeastern 

 Arkansas, Oklahoma, western Louisiana and central Texas (Devil's River); 

 Mexico. Considerably extended by cultivation. 



Note on nomenclature. — Formerly designated as Carya olivaeformis Nuttall, 

 and by some authors now as Carya pecan Engler and Graebner. 



NAMES IN USE 



Pecan (Va., N. C, S. C, Tenn., Ga. Pecan Nut (La.), 

 (cult.), Ala., Miss., Tex., La., Ark., Pecanier (La.). 

 Mo., 111., Ind., Iowa., Kans.). Pecan-tree (La.). 



X Hicoria nussbaumerii (Sargent) Sudworth. 



Nussbaumer Hickory (Hybrid). 



Range. — Originally found in the bottom between Mascoutah and Fayette- 

 ville, St. Clair County, Illinois. A tree grown from seed obtained from Illinois, 

 probably of the same parentage, and cultivated at Cedar Rapids, Iowa, has been 

 called the "Floyd Nut." Grafted plants from a tree found at Mount Vernon, 

 Posey County, Indiana, and bearing a similar nut, were later distributed from 

 Washington, Georgia, as the " McCallister." Another of these trees was de- 

 tected in the neighborhood of Burlington, Iowa, and also one, known as the 

 "Rockville nut," from near Rockville, Mo. 



Note on nomenclature. — Believed to be a hybrid between Hicoria -pecan 

 (Marshall) Britton and Hicoria laciniosa (Michaux f.) Sargent. 



» The name Juglans californica S. Watson was previously made to include \ wo distinct trees, one of 

 which grows in the southern California coast region and the other in the Central coast region. Prof. W. L. 

 Jepson first pointed out (Bull. So. Calif. Acr-ii. Sci., Vol. 7, p. 23, 1908) that the more northern tree is 

 varietaily distinct from the southern tree and designated it as Juglans californica var. Hindsii. It se 

 to the writer, however, that this walnut is specifically distinct.
