gated exactly in the same manner as F. A^na.. There being no varieties, it 

 does not require to be continued by grafting. 



Statistics. In the environs of London, at Syon, it is 30 ft. higli ; in the Fulhani Nursery, 40 years 

 years planted, it is 30 ft. high ; in Staffordshire, at Arley Hall, there is the fine specimen mentioned 

 above, which is 54| ft. high ; in Wiltshire, at Longleat, 65 years planted, it is 35 ft. high. In France,

 ()+J, is a small tree, with 

 iv.ite or, entire subtrilobate 

 pubescent under- 



cath ; a native of Nootka 

 •^ )und,and other partsof the 

 north-west coast of North 



\inerica. The wood is em- 

 I)Ioyed for making wedges ; 



nd the fruit is used as an 



rticle of food, under the 

 I] ime of pow-itch, by the 

 ' henook Indians. It flowers ^^ 



n April and May. It is v 



nuch to be desired that this species of P^rus were introduced into 

 l5ritain ; since it seems the only one of the section which is indigenous 

 to the western hemisphere. Judging from the engravings in Dr. Hooper's 

 work (from which our J?^. 642. has been reduced to our usual scale of 

 2 in. to 1 ft., and^g-. 643. has been copied of the natural size), it is a very 

 Imndsome species.
