OUR NUT TREES 



ovoid, pointed, 8-ribbed nut has a thick shell but 

 the flesh within is sweet. The Chinese J. cathay- 

 ensis is a bush or slender tree with a small, very rough 

 nut of no particular value. It has not proved very 

 hardy in the Arnold Arboretum. 1 introduced it 

 first to England in 1903 and to this country in 1908. 

 The Manchurian /. mandshurica rivals the American 

 Butternut in size and the nut shows a decided ap- 

 proach to that of the true Walnuts. The shell is very 

 thick and the flesh limited in quantity. It is a com- 

 mon tree in the forests of Korea and is very hardy. 

 The little-known /. stenocarpa of Russian Manchuria 

 is only a form of /. mandshurica. 



Having dealt with all the species of Juglans within 

 our province it remains to say a word or two about 

 the hybrids though none of them is valuable for the 

 nuts. A supposed hybrid between the American J. 

 nigra and J. cinerea was described as long ago as 1857 

 from a tree in the Botanic Garden at Marburg in 

 Germany. The other hybrids, and there are sev- 

 eral, are between the European Walnut (_/. regia) and 

 the American species. One of these is a cross be- 

 tween J. regia and J. nigra and known as /. intermedia 

 var. Vilmoreana. This originated at Verri^res les 

 Buisson, near Paris, about 1805. The original tree is 

 now nearly 100 feet tall and 10 feet in girth; in bark, 

 branchlets, and buds it is intermediate, but in habit
