one in the grounds of G. May, Esq., Strood House, Heme, 

 remarkable for its size and beauty. 



U. suberosa alba Masters. [ U. c. s. alba Arb. Brit.'] A lower 

 tree, of more compact growth, than the two preceding varieties ; 

 and often growing into an oval, or rather cone shaped, head. 

 Young shoots pubescent. Foliage thickly set. Bark much 

 wrinkled, and becoming white with age. Fine specimens of this 

 variety are growing in Lee Park, near Canterbury. 



Several of the varieties of the above list are, we believe, 

 wanting in the collections about London ; and some of them 

 seem of great value as timber and ornamental trees. We wish 

 much that some gentleman near London, who could spare a 

 sufficient quantity of land, would plant an ulmarium, and col- 

 lect varieties from all parts of Europe. The kinds might then 

 be determined with accuracy, and also the comparative value of 

 the timber. If the business were properly set about, all the 

 results of real utility might be attained in ten years after plant- 

 ing ; for in that period all the sorts worth growing for their 

 timber would be 50 ft. high, with trunks 1 ft. in diameter at the 

 surface of the ground. 



U. effijsa Arb. Brit, is a most remarkable tree, quite as 

 easily known in winter as in summer. The finest specimen in 

 England is at White Knights, where, in 1835, it was upwards 

 of 60 ft. high. There are three trees of this elm in the Horti- 

 cultural Society's Garden, and there are plants at Messrs. Lod- 

 diges's. 



A'\x\ns cordifolia Arb. Brit, is a most beautiful tree, intro- 

 duced in 1818, scarcely ever seen in plantations, though there 

 is abundance of plants at Messrs. Loddiges's, and in the Woking 

 Nursery. 



Quercus. All the species and varieties of oaks are beautiful. 

 The oaks of Europe may all be reduced to three species : Q. 

 Rohnr, the British oak ; Q. Cerris, the French, Turkey, and 

 Austrian oak; and Q. /^lex, the Spanish and Italian oak. To 

 these may be added Q. ^'gilops and Q. Suber, with two or 

 three others. The American oaks may almost all be reduced 

 to Q. alba, Q. rubra, Q. Prinus, and Q. virens. The finest 

 trees of American oaks in England are at Strathfieldsaye. The 

 only nursery which we know, which contains a large stock of 

 Q. R. sessiliflOrum, is that of Young and Penny at Milford. The 

 weeping oak at Moccas Court, and the curious cut-leaved oak 

 of Mr. Fenessey, have been already noticed. One of the finest 

 kind of weeping oaks in England is at Hackwood Park, in 

 Hampshire, of which we have been kindly promised a drawing, 

 which we shall have engraved for the Arboretum. 



Populus. A new variety {P. nigra salicifolia), with leaves not 

 unlike those of ASalix viminal.s, has lately been introduced by
