THE WALKUT. 337 



named, Thnnberg had described a Japan walnut under 

 the name of Juglans nigra, probably the same as Lou- 

 reiro's species, with reddish husk, but as this name had 

 already been given to an American species it had to be 

 dropped. Maxiomowicz also describes what he supposed 

 to be a distinct species, found in the forests of Mand- 

 shuria under the name of /. Mandshurica (1873), but 

 it is doubtful if it is anything more than one of the 

 many wild forms of the species found widely distributed 

 over eastern Asia. The red or black fruited walnut of 

 Loureiro (/. Oatappa), and Siebold's black walnut {J. 

 nigra), are probably the same as the Ailantus-leaved 

 {J. ailantifolia), recently described in Nicholson's 

 "Dictionary of Gardening," London, Eng., 1884, the 

 origin of which is said to be uncertain. It is Juglans 

 Mandshurica, Maxim, in Alphonse Lavall^e's "Cata- 

 logue of Arboretum Segrezianum." As described in 

 this work, the young fruit is violet-red, and produced in 

 Ipng pendulous clusters, the latter being one of the 

 marked characteristics of these Oriental walnuts. But 

 whether we admit that there is but one or a dozen spe- 

 cies of these Eastern walnuts, it cannot be of any special 

 interest to the practical nut culturist, for to him their 

 economic and commercial value is of more importance 

 than scientific nomenclature. 



Up to the present time we have only succeeded in 

 obtaining two species of these walnuts, or perhaps only 

 one species and one variety; but we certainly have two 

 distinct forms, both coming from Japan, and distrib- 

 uted under the names given them by Maxiomowicz, viz. : 



Juglans Sieboldtana (Siebold Walnut). — Leaflets 

 sessile, usually fifteen, five to seven inches long, oblong- 

 pointed, thin, soft, downy, serratures very shallow, pale 

 green above and somewhat lighter beneath ; footstalks 

 densely clothed with clammy hairs ; fruit in long pen- 

 dulous clusters of a half dozen to a dozen, one and a
