ARBORETUM AND FRUTICETUM.

PART III.

Description, Sfc. Trees, rarely exceeding the middle size; and some solow 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 timberof great value, except for the charcoal which may be made from it. Allthe species prefer a moist soil, or one in the vicinity of water. A. glutinosaripens seeds freely, as do most of the other sorts; but all the latter aregenerally propagated by layers. The only truly distinct species appear to usto be, A. glutinosa, A. cordifolia, A. incana, A. oblongata, and A. viridis;which last seems an intermediate species, or connecting link, between yl'lnusand .Betula.

y 1. A. glutino'sa Geertn. The glutinous, or common, Alder.

A tree, from 30 ft. to 60 ft. high; a native of Europe, from Laplandto 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.

(N. Du Ham.') Thouin, in the year1819, in the Nouveau Corns <TAgricul-ture, states that the cut-leaved alder wasfirst found by Trochereau de la Berliere,and planted by him in his garden nearSt. Germain, where the stool still remains from which all the nurseriesof Paris have been supplied with plants, and, probably, all Europe.

¥ A. g. 4 q uercifolia Willd., 1. c., Lodd. Cat., ed. 1836. — Leaves sinu-ated, with the lobes obtuse.

¥ A. g. 5 oxyacanthcefolia ; A. oxyacanthmfolia Lodd. Cat.,e d. 1836; andouryig. 1539.—Leaves sinuated and lobed; smaller than those of thepreceding variety, and somewhat resembling those of the commonhawthorn.

¥ A. g. 6 macrocarpa ; A. macrocarpa Lodd. Cat., 1836; has the leavesand fruit rather larger than those of the species, and is also of morevigorous growth.

¥ A. g. 7 foliis variegatis 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 asvarieties of A. glutinosa; or, perhaps, of A. incana; but the plants are sosmall, that we are unable to determine whether they are sufficiently distinctto be worth recording. Among these names are, A. nigra, A. rubra, A.plicata, and A. undulata. A. rubra is said to be a native of the Island ofSitcha. ( Annal. des Scien. Nat., 3. p. 237.) Some of the sorts treated as
