102 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 



little known and very ornamental species and varieties, especially 

 those of a " weeping " habit, which are worthy of attention, and 

 all the sorts ave particularly well suited for planting in moist 

 soils, where they delight to grow, and generally form very graceful 

 and attractive objects. 



The Elder {Sambucux). 



Considering that this genus has such a wide distril)Ution over 

 Europe, Asia, and America, it is somewhat remarkable that there 

 are only three or four species known. The common species, ^S*. 

 nigra, is so familiar that it is unnecessary to say more than that 

 it is an eflfective tree, and that, take it for all in all, it is one of 

 the finest of our strong-growing deciduous shrubs or low trees, 

 and, along with S. racemosa and the many beautiful varieties of 

 both species, is well deserving of more extensive inti'oduction into 

 ornamental plantations. We need not add that all the varieties 

 are quite hardy, and all require for their proper development, 

 whether as regards foliage, flowers, or fruit, to be planted in o[)en 

 sunny aspects, and in well-drained ground. 



TuE LniE {Tilia). 



Widely distributed over both Europe and America, the noble 

 trees which compose this comparatively small gi'oup ai'e, without 

 exception, hardy in this country, and, with their varieties, are 

 ornamental in the highest sense. From the European type, the 

 glory of our parks and avenues, to the gi-and species from Ameiica, 

 with their now numerous varieties, we have an array of fine trees, 

 to which the ea~]v planters in Britain were strangers. 



The Elm (Ulmus). 



No collection of ornamental trees would be complete without 

 some representatives of the Elms, which, for stateliness of habit, 

 tine variegations, and thorough hardiness in almost every situation, 

 commend themselves to all who can appreciate the picturesque in 

 the grouping of trees. The two species, U. campestris and U. 

 viontaTUi, which form the type of the genus, are indigenous to 

 England and Scotland ; and from these have sprung a pi'ogeny of 

 varieties, all of which arc exceedingly interesting.
