the summit of the Boar's Hill range, which is a prominent object from 

 the Ridge way — 



'To where the elm-tree crowns 

 The hill behind whose ridge the sunset flames ; . . . 

 The signal-elm, that looks on Ilsley Downs, 



The Vale, the three lone weirs, the youthful Thames. . . . 

 That single elm-tree bright 

 Against the west.' 

 But the tree which is now associated with Matthew Arnold is really 

 an oak of a somewhat unusual shape, reminding one rather of the 

 Italian Pine. 



A considerable number of forms of the Elm have been described, 

 but at present there is very considerable divergence of opinion 

 respecting the description and the synonymy. 



Var. STRiCTA ^Lindl. Syn. ed. ii, 227, as a species'). The Cornish Elm. 

 Is evidently not native. It may be seen at Cumnor, and is extensively 

 planted at Lockinge by Lord Wantage, and also in Windsor Park. 



Loudon says that at Bagshot Park this variety, at 70 years of age, 

 reached a height of 70 feet. 



Var. suBERosA (Moench, I.e., as a species), has the branches thickly 

 covered with corky layers. In its extreme state it may be more 

 frequently met with as a hedgerow shrub or small tree. ' TJlmus 

 campestris with very corky bark near Cumnor Hurst,' W. T. Dyer, may 

 be this. I have seen it at Cumnor, and it is plentiful about Besils- 

 leigh, Cothill, Radley, Wittenham, Greenham, near Newbury, &c. 



Loudon says that many of the trees at Windsor are U. suberosa, the 

 Dutch cork-barked Elm. 



Var. GLABRA (Sm. E. B. t. 2248, as a species'). 



There are some fine specimens of what I believe to be this variety 

 near Besilsleigh ; it forms a large tree with more spreading branches 

 than the Cornish Elm. Mr. J. G. Baker confirmed the name. 



I have followed Syme in the descriptions of the varieties of the Wj^cli 

 Elm, but his account of the forms of the Common Elm is very im.perfect. 



I have never observed seedling elms in Berkshire ; such are of rare 

 occurrence in Britain. 



U. sativa occurs in all the bordering counties. 



HUMULUS, Linn. Gen. n. 989 (Lupulus, Tournefort, Inst. t. 309). 



H. Lupulus, Linn. Sp. PI. 1038 (1753). Hop.

Top. Bot. 367. Syme, E.B. viii. 132, t. 1284. Nyman, 658. Fl. Oxf. 263. 



Native. SeptaL Damp hedges and thickets. Common and generally 

 distributed through the lower parts of the county. Rare on the 

 uplands. Perennial twining herb. May-August. 



First record. Sunninghill, Sir Joseph Banks, in Herb. Brit. Mus. 1773.
