throw up suckers ; which convinces us that it is only a variety of that species. 

 The propagation, culture, &c., of U. glabra and its varieties are the same as in 

 the preceding sort ; but, to preserve the latter distinct, they ought to be grafted. 



Varieties. In consequence of U. glabra ripening seeds in different parts of 

 England, many varieties have been raised from it, most of which are distin- 

 guished by great rapidity of growth. It is difficult to determine, in every 

 case, whether the varieties of U. (m.) glabra are not nearer to U. montana, 

 than to that sub-species ; and, in some instances, they appear to partake of 

 the character of U. campestris and U. (c.) suberosa. T. A. Knight, Esq., 

 informs us that from seeds of one variety of U. (m.) glabra, viz. the Down- 

 ton elm, which were ripened in the cold climate of that part of Shropshire, 

 he " raised plants which are so perfectly similar to the U. suberosa*, and 

 which approximate so nearly to the character of the U. glabra, that " he 

 does "not doubt but that the U. campestris, U. suberosa, U. glabra, and 

 three or four other varieties which" he has " seen in different parts of 

 England, are all varieties only of the same species." 



A. Timber Trees. 



* U. (w.) g. ] vulgdris. The common smooth-leaved Elm. 



U. (w.) g. 2 vegeta. U. montana vegeta in the Horticultural Society's 

 Garden ; U. americana Masters ; the Huntingdon Elm, the Chi- 

 chester Elm, the American Elm in some places, and perhaps the 

 Scampston Elm. This is by far the most vigorous-growing kind of 

 elm propagated in British nurseries, often making shoots from 6 ft. to 

 10 ft. in length in one season ; and the tree attaining the height of 

 upwards of 30 ft. in ten years from the graft. Raised at Huntingdon 

 about 1746, from seed collected in that neighbourhood, by Mr. 

 Wood, nurseryman there. 



U. (w.) g. 3 var. The Scampston Elm. Variety of U. glabra, and 

 very little different from the preceding kind. 



i U. (?.) g. 4 major. U. glabra major Hort. Dur. ; the Canterbury Seed- 

 ling. Of more vigorous growth than the species, and, indeed, a rival 

 to the Huntingdon elm in quickness of growth. Judging from the 

 specimens of this variety sent to us by Mr. Masters, we should say 

 that it belongs fully as much to U. montana as to U. (m.) glabra. 



U. (w.) g. 5 glandulosa Lindl. Leaves very glandular beneath. 



y- U. (m.) g. 6 latifolia Lindl. Leaves oblong, acute, very broad. 



U. (rn.) g. 7 microphylla Hort. U. g. parvifolia.. Leaves small. 

 Horticultural Society's Garden. 



B. Ornamental or curious Trees. 



*t U. (m.) g. 8 pendula. U. campestris pendula Hort. Dur.; the Down- 

 ton Elm. Raised in Smith's Nursery, at Worcester, in 1810, 

 from seeds obtained from a tree in Nottinghamshire. Mr. Knight 

 of Downton Castle purchased some of these trees ; and one them 

 turned out to be that weeping variety which has since obtained the 

 name of the Downton elm. 



3t U. (m.) g. 9 variegdta Hort. Leaves variegated. Hort. Soc. Garden. 



U. (m.) g. 10 ramulosa Booth. Branches mere twiggy than the species. 



? 7. U. A'LBA Kit. The whitish-leaved Elm. 



Identification. Kitaib., quoted in Rcem. et Schult. Syst. Veg., 6. p. 300.; Willd. Baumz., p. 518. 

 Engraving. Our Jig. 0000. in p. 0000. 



Spec. Char., $c. Bark grey brown ; smooth, not chinky. Leaves with 

 downy petioles ; and disks oblong, acuminate, 2^ in. long, unequal at the 

 base, doubly and very argutely serrate ; above, deep green ; beneath, downy, 

 and becoming obviously whitish. (IVilld.} A large, deciduous tree. Hun- 

 gary; said to have been introduced in 1834, but we are not aware that the 

 plant is in British gardens.
