1678 ARBORETUM AND FRUTICETUM. PART 111. 



Description, $c. Trees, rarely exceeding the middle size; and some so 

 low as to be considered shrubs. With the exception of A. glutinosa lacini- 

 ata and A. cordifolia, the species are not very ornamental ; nor is the timber 

 of great value, except for the charcoal which may be made from it. All 

 the species prefer a moist soil, or one in the vicinity of water. A. glutinosa 

 ripens seeds freely, as do most of the other sorts; but all the latter are 

 generally propagated by layers. The only truly distinct species appear to us 

 to be, A. glutinosa, A. cordifolia, A. incana, A. oblongata, and A. viridis; 

 which last seems an intermediate species, or connecting link, between A'inus 

 and J^etula.

Volume. 



Spec. Char., $c. Leaves roundish, wedge-shaped, wavy, serrated, glutinous, 

 rather abrupt ; downy at the branching of the veins beneath. (Eng. FL, iv. 

 p. 131.) A tree, from 30 ft. to 60 ft. high ; a native of Europe, from Lapland 

 to Gibraltar ; and of Asia, from the White Sea to Mount Caucasus ; and, 

 also, of the north of Africa; flowering, in Britain, in March and April. 



Varieties. 



y A. g. 2 emargindta Willd. Baum., p. 19., 

 has the leaves nearly round, wedge- 

 shaped, and edged with light green. 



* A. g. 3 lacinidta Ait. Willd., 1. c., Lodd. 



Cat., ed. 1836; A. g. incisa Hort.', our 

 ^g.1538., and the plate of a fine tree at 

 Syon, in our last volume; has the leaves 

 oblong and pinnatifid, with the lobes 

 acute. Wild in the north of France, 

 particularly in Normandy, and in the 

 woods of Montmorency, near Paris. 

 (N. Du Ham.) Thouin, in the year 

 1819, in the Nouveau Cours d' Agricul- 

 ture, states that the cut-leaved alder was 

 first found by Trochereau de la Berliere, 

 and planted by him in his garden near 



St. Germain, where the stool still remains from which all the nurseries 

 of' Paris have been supplied with plants, and, probably, all Europe. 



* A. g. 4 quercifolia Willd., 1. c., Lodd. Cat., ed. 1836. Leaves sinu- 



ated, with the lobes obtuse. 

 A. g. 5 oxyacanth&folia ; A. oxyacanthaefolia Lodd. Cat., ed. IS 



our fig. 1539. Leaves sinuated and lobed ; smaller than those of the 

 preceding variety, and somewhat resembling those of the common 



* A. #. 6 mdcrocarpa ; A. macrocarpa Lodd. Cat., 1836 ; has the leaves 



and fruit rather larger than those of the species, and is also of more 

 vigorous growth. 



A.g. 7 foliis variegdtis Hort. has the leaves variegated. 



Other Varieties. There are some other names applied to plants in the col- 

 lection of Messrs. Loddiges, which, we think, can only be considered as 

 varieties of A. glutinosa; or, perhaps, of A. incana; but the plants are so 

 small, that we are unable to determine whether they are sufficiently distinct 

 to be worth recording. Among these names are, A. mgra, A. ritbra , A 

 plicdta, and A. unduldta. A. rubra is said to be a native of the Island of 

 Sitcha (Annal. des Sewn. Nat., 3. p. 237.) Some of the sorts treated as
