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. I introduced it 

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

 The Manchurian J. mandshnrica 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 J . stenocarpa of Russian Manchuria 

 is only a form of J. mandsburica. 



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 /. 

 nigra and /. 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 (J. regid) and 

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

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

 var. Vilmoreana. This originated at Verrieres 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
