1896 The Trees of Great Britain and Ireland 



Ulmus viscosa, Koch, Dendrologie, ii. pt. i. 416 (1872), appears to differ very 

 little from var. Webbiana. It is represented at Kew by a stunted specimen, 

 obtained from Booth in 1871. 



12. Var. virens, Henry. Kidbrook Elm. 



Ulmus campestris, var. virens, Loudon, Arb. tt Frut. Brit. iii. 1376 (1838). 



A tree, narrowly pyramidal in habit, with long ascending branches, retaining 

 its foliage till December. Branchlets slender, glabrous. Leaves oval, about 3 to 4 

 in. long, and i| to 2 in. wide, long-acuminate at the apex, coarsely biserrate, glabrous 

 and smooth above, slightly scabrous beneath, with numerous glands ; lateral nerves, 

 about twelve pairs, remote, often forked. Flowers similar to those of the Hunting- 

 don elm. Samarae similar, but smaller. 



The only specimen of .this tree which I have seen is one about 40 ft. high at 

 Ashwell Bury, near Baldock. In habit it somewhat resembles the Huntingdon 

 elm, but is more narrowly pyramidal. It retained its leaves in 1910 till the first 

 week in December. It is probably identical with Loudon's tree, of which he says : 

 " Notwithstanding its name of Kidbrook elm, a place in Sussex, it is a Cornish 

 variety," probably on account of its pyramidal habit. Var. virens appears to be 

 unknown in nurseries at the present day. 



13. Var. betulcefolia, Loudon, Arb. et Frut. Brit. iii. 1376 (1838). 



Ulmus betulcefolia, Loddiges, Cat. 1836. 



A tree, pyramidal in habit, with ascending branches. Leaves ovate-oblong, 

 up to 3^ to 4 in. long and \\ in. broad, long-acuminate at the apex, tapering to a 

 cuneate but unequal base, coarsely biserrate; lateral nerves 12 to 14 pairs. 



This tree, which is readily distinguished by its foliage and habit, is represented 

 by a good specimen in the Cambridge Botanic Garden. It is occasionally seen in 

 hedgerows in Herts and Huntingdonshire. 



Distribution 



U. nitens is a native of central, western, and southern Europe, Algeria, Asia 

 Minor, Caucasus, Armenia, Persia, and Turkestan. In eastern Asia it is replaced 

 in Manchuria, Korea, and Japan by the closely allied species, U . japonica. 



In Europe, this species has a more southerly distribution than U. montana, 

 and is unknown in Denmark, Sweden, and Norway as a wild tree, though it is 

 said to occur, possibly planted, on the island of Gothland, in the Baltic. In Russia, 

 it is limited to the southern provinces, its northern limit passing through Grodno, 

 Volhynia, Chernikof, Tambof, Saratof, Samara, and Orenburg. It is especially 

 common in the south-west, occasionally forming pure woods, one of which is said by 

 Koppen 1 to extend for fifteen versts in the valley of a tributary of the river 

 Ingul in Kherson. It occurs in the Crimea, and in the Caucasus, where it grows 

 from sea-level to an altitude of 6000 feet.
