ably. Many of the kinds are remarkable 

 for the beautiful autumnal colouring of the

 can tree 30-40 ft. high, with sometimes 

 corky winged branches. Leaves 1-2J in. 

 long, ovate-oblong or oblong lance-shaped, 

 thickish, more or less smooth above, 

 downy beneath. Flowers on slender 

 drooping jointed stalks with obovate seg- 

 ments. Fruit ovate, more or less downy, 

 fringed. 



Culture (tc. as above. 



U. americana (American or White 

 Ehn). — An ornamental N. American tree 

 80-100 ft. high. Leaves 2-4 in. long, 

 obovate-oblong or oval, abruptly acute, 

 sharply and often doubly serrate, smooth- 

 ish above, more or less down.y beneath. 

 Flowers drooping, with a 7-9-lobed 

 perianth. Fruit oval, about i in. long. 

 There is a ' weeping ' or drooping form 

 called pendula. 



Culture dtc. as above. 



U. campestris (Common Elm ; Ahne ; 

 Aume Tree). — A fine and well-known 

 British tree about 125 ft. high when full 

 grown, the rugged trunk often attaining a 

 girth of more than 20 ft., the roots send- 

 ing up an abundance of suckers. Leaves 

 2-3 in. long, ovate-oblong, somewhat cus- 

 pidate. Flowers with 4 stamens. Fruit 

 usually obovate. 



There are several varieties of this 

 species, the most ornamental being per- 

 haps the pretty Variegated Elm, which 

 has the leaves striped and blotched with 

 white, and is very ornamental in spring. 

 The variety striata is distinguished by its 

 rigid, erect growth ; tortuosa, the Twisted 

 Ehn, is a peculiar form ; and virens, the 

 Kidbrook Ehn, is almost evergreen in 

 winter, and therefore valuable. Other 

 forms are acutifolia,Berardi,hetulcBfoUa, 

 laUfoUa aurea, I. a/rgentea, myrtifoUa 

 (or huxifoUa), &c. 



Culture dc. as above. 



U. fulva (Slippery or Bed Elm). — A 

 N. American tree with ovate-oblong taper- 

 pointed doubly serrate leaves 4-8 in. long, 

 very rough above, softly downy beneath, 

 and sweet-scented when drying. Flowers 

 nearly sessile, with 7-9 perianth segments 

 and stamens. Fruit roundish. There is 

 a weeping form called pendula. The seeds 

 of this species do not sprout until the fol- 



lowing year, and should be stratified in 

 layers of wet sand until they are sown. 

 Culture Ac. as above. 



U. glabra (W^cJ^ Ehn). — BotanicaUy 

 this is only a form of the Common Ehn. 

 It grows 60-80 ft. high, and has elliptic- 

 oblong doubly serrate smooth leaves, very 

 unequal at the base. Flowers nearly 

 sessile, 5 -cleft. Fruit obovate, deeply 

 cleft, rather small. There are several 

 forms, including pendmla, a 'weeping' 

 variety known as the Downton Elm; 

 variegata, with variegated leaves. 



Culture £c. as above. 



U. montana (Scotch or Wych Elm). — 

 A British and European tree 80-120 ft. 

 high with long spreading branches and 

 large ovate -oblong doubly and trebly 

 serrate taper-pointed leaves 3-6 in. long. 

 Flowers 5-7 -parted. Fruit oblong or 

 roundish, slightly cleft. 



There are several distinct and hand- 

 some varieties, among which may be 

 mentioned criapa (or urticiBfolia), with 

 crisped thickly plaited and wrinkled 

 irregularly toothed leaves, habit dwarf 

 and slender ; fastigiata, the Exeter or 

 Ford's Elm, a remarkable pyramidal 

 form with leaves peculiarly twisted; 

 there is also a golden-leaved form of it 

 called fastigiata av/rea ; nigra, the Black 

 Irish Elm, a more spreading tree than the 

 type ; pendula is a beautiful form with 

 branches spreading fanlike, sometimes 

 horizontally, sometimes perpendicularly, 

 and a. variegated form called pendula 

 variegata, the leaves of which are mottled 

 with white, and vegeta, the Chichester or 

 Huntingdon Elm, a very vigorous kind, 

 often attaining a height of 30 ft. in about 

 10 years when grafted. Comuhiensis, the 

 ' Cornish Ehn,' has small leathery strongly 

 veined leaves and bright brown branches. 

 It comes into leaf somewhat later than the 

 Common Elm. 



Other Elms worthy of mention are 

 parviflora, from China and Japan, 

 pedunculata (or effusa), a European tree 

 50-60 ft. high, and suherosa, the Cork- 

 barked Elm, really a variety of cam- 

 pestris. It grows 60-100 ft. high, and 

 has a form with beautifully variegated 

 leaves. 



Culture dc. as above.
