NEWER DEOIDtrOUS TREES AITD SHRUBS. 459 



five years planted, Jfifteeu feet high. At Syon House, near 

 London, there is.a specimen, twelve feet. In this country, as 

 yet, it, is rarely to be met with in our ornamental places, 

 which is the more, remarkable as we do not know a shrub; 

 which should be plantfed before it It comes into bloom a 

 month; or six weeks later than the other horse-chestnutSj and at 

 a period, too, when very few shrubs .'are in flower, and continues^ 

 a long time. Our best plant afWodenethe — of which Fig. 91 

 is a sketch;-r-twelve years old, is sixty feet in circumference 

 and about eight faet high, and has, at the time we write, between 

 three and four hundred racemes of flowers, the feathery lightness 

 of which, and the fine umbrageous character of the leaves ren- 

 der it a most striking and attractive object. 



Pavia rubra (Red-flowering), — which is merely mentioned 

 by Mr. Downing, and which is now better known, is a shrubby 

 tree, seldom exceeding twenty feet, with reddish flowers suflS- 

 ciently distinct to make it desirable — though Pavia Jiumilis 

 penduh, (the Weeping red pavia), is even more desirable and at- 

 tractive. Mr. Loudon considers this one of the most beautiful 

 and interesting forms oi Pavia, and recommends horse-chestnuts 

 of twenty to thirty years' growth to be grafted all over with it 

 at the points of the shoots ; care being taken afterwards, once 

 or twice every year, to rub ofi" all the buds from the stock as 

 soon as they appear, so that the entire force of the plant may 

 be direoted to the nourishment of the scions. 



Pavia carnea pubescens (Downy leaf), from the fact of the 

 whole plant, including the young wood, being covered, with 

 pubescence. 



P. purpurea (Purple) ; P. rubra atrosanguinea (Dark red) ; 

 and P. carnea superba (Pale red), are all new varieties to be 

 obtained in this country, and of greater or less merit. 



Alnus. The Aldeb. 



The principle additions to this genus, since the previous 

 edition of this work, have been A. cordifolia, (Heart-shaped), 

 a tree of some magnitude,' a native of Calabria, with 

 large, deep green,, shining leaves, rather broad and deeply
