392 Account of the Arboretum noia formiyig 



should have ; viz., tempting customers. It may, indeed, tempt 

 a few, who have no real taste for trees and shrubs, and who are 

 ambitious of having whatever is new, in order to display their 

 wealth ; but we know, from experience and observation, that, 

 with the great majority of purchasers, the excessive multi- 

 plicity of varieties operates as a stumbling-block, puzzles in 

 making a choice, destroys the hope of ever having a good col- 

 lection, and actually deters from purchasing. It cannot be 

 denied that such has been the effect in the case of roses, goose- 

 berries, apples, pears, and other fruit trees ; and, we believe, 

 more of these articles wOuld be sold, if the catalogues were made 

 more select. In fact, we know this to have been the case as 

 respects roses and gooseberries. In the course of examining 

 the trees and shrubs in the arboretum of the Horticultural So- 

 ciety, and in that of Messrs. Loddiges, we have found a number 

 of mere varieties elevated to the rank of species ; and of the 

 same variety under different names, or so much alike as not to 

 be worth retaining as distinct. This is unavoidable in forming 

 collections like those of the Horticultural Society and Messrs. 

 Loddiges, in which the object is, in the first instance, to bring 

 together specimens of every tree or shrub, pretending by its 

 name to be distinct, though many of these must necessarily be 

 duplicates ; but it will be the great object of our Arhoretum Bri- 

 tannicum to point out what is really distinct, whether a species 

 or a variety, and to give all the synonymes which we can do cor- 

 rectly ; so as, if possible, to put it in the power of our readers to 

 avoid having the same thing sent to them imder different names, 

 or having two things which are not truly and obviously distinct. 

 While we state this respecting varieties, we wish it not to be 

 forgotten that all the most valuable plants, both of agriculture 

 and horticulture, are varieties of species ; which varieties have 

 been produced either by accident or design, and have been 

 selected by gardeners and nurserymen exactly in the manner 

 which has given rise to the excess of which, in various articles, 

 there is at present just reason of complaint. But it is time to 

 conclude this article, by laying before our readers Mr. Paxton's 

 catalogue of the orders and genera of the trees and shrubs 

 planted, or to be planted, in the arboretum at Chatsworth.
