Introduced in 1820; flowering in April and May. This is a handsome upright-growing shrub, or low tree, attaining the height of 12 ft., although only four years planted. Branches of a brownish green fuscous colour, somewhat downy, but ultimately becoming smooth; the young twigs are of a yellow purple, pubescent, and soft to the touch. Leaves elliptic, about 1} in. long; dull green and villous above, whitish and silky beneath, and reticulated with large prominent veins; the young leaves have rather a silky silvery appearance; while the old ones become more firm and pubescent, their margins entire, or sometimes very distinctly marked with shallow serratures. Catkins about 1 in. long. A very ornamental plant, but not fit for cultivation for economical purposes. There are plants at Woburn Abbey, Henfield, and Flitwick House, and also in the Goldworth Arboretum.

coriaceous, with reticulated veins, nearly glabrous; glaucous beneath. Ovary sessile, downy. (Smith E. F.) The young foliage is often floccose. (Br. Fl., ed. 2.) A native of England, and the high mountains in Wales and Scotland; flowering from May to July. Koch has stated its European places of growth to be as follows :- Moist rocks, or other moist places, of the highest mountains above the limit of perpetual snow, in Piedmont, Savoy, Switzerland, the Pyrenees, Germany, Carpathia, Transylvania, Britain, and Lapland. Hooker has remarked (Br. Fl., ed. 2.) that he possesses S. reticulata, obtained from Arctic America, and having long silky hairs 1323 on both surfaces of the leaf. Mackay has not inserted the species in the Flora Hibernica. Lightfoot, as quoted by Smith, has noted the kind of soil in which it occurs on many of the Scottish highland mountains to be micaceous. “Larger than S. herbàcea, with stout, woody, procumbent stems and branches, either mantling the alpine rocks, or spreading on the ground in large patches. Leaves 3 from each bud, on long slender footstalks, without stipules; alternate, nearly orbicular, or somewhat elliptical, 1 in. broad, firm, coriaceous though deciduous, entire, with an occasional notch at the end; the upper surface wrinkled, of a deep shining green ; the under surface very glaucous or whitish, beautifully reticulated with abundance of prominent veins, now and then somewhat silky. Catkins solitary at the end of the same branch, above the leaves ;” of a purplish red colour, as are the buds. The veins on the under surface of the leaf are of a purplish colour. (Linnæus.) This is a most remarkable species, totally different from any other; and it ought not to be wanting in any collection. Smith has deemed it akin to S. herbácea. Koch has associated the two in the same group. In its rounded wrinkled leaves, villous when young, in its buds, and in its branches, it bears much similarity to S. càprea, though it is widely different in its inflorescence. There are plants in the arboretum of Messrs. Loddiges, in the Fulham Nursery, and in the Goldworth Arboretum.

App. i. Reticulate described, but not yet introduced. S. vestita Pursh F1. Amer. Sept., 2. p. 610., Smith in Rees's Cyclo., No. 76., differs from S. reticulata, in having the under side of its leaves clothed with long silky hairs. Pursh calls it a very elegant species. It is a native of Labrador.

Stamens 2 to a flower, Ovary very downy, or silky, sessile. Plants small

shrubs, most of them upright; all, or most of them, remarkable for their foliage, which consists of leaves that are oblong-lanceolate, soft, hairy, silky, and, in most, white and cottony on the under surface. The kinds are very closely akin, each among the rest. (Hook. Br. Fl., ed. 2., adapted.) Only S. glaúca L., S. arenària L., and S. Stuartiāna Smith, are associated together under the above characteristics in Hook. Br. Fl., ed. 2. Of the kinds brought together below, as agreeing more or less in the quality of similarity, Mr. Borrer has indicated S. elæagnifòlia Forbes (elæagnoides Schleicher), S. glauca L., S. sericea Villars, S. Lappònum L., S. arenària L., S. arenària L.

The Scres.

in the willow garden at Woburn Abbey, in April and May. This species grows to the height of 5 ft. or 6 ft.; quite erect, with dark green, rounded, pubescent branches; the old ones shining and glabrous after the first year. Leaves from 2 in. to nearly 3 in. or 3} in. long, and from lin. to 1} in. broad; densely silky on both sides, elliptic-lanceolate, with acute oblique points; the lower rather obtuse; margins entire ; whitish and glaucous beneath; closely covered with long, compressed, silky hairs. Midrib prominent, yellow. Footstalks yellow, pubescent, very stout, and much dilated at the base. Catkins l in. or more in length, appearing before the expansion of the leaves. They remain on the plant during the greater part of the summer ; by which peculiarity this very distinct species is readily known from every other. The female plant is figured and described in the Salictum Woburnense.

Introduced in 1812. “ This appears to be a very distinct species from glauca, elæagnifòlia, arenària, lanàta, and Stuartiana. It grows with me to about 1 ft. high, with short, pale, decumbent branches ; sometimes the young twigs are tinged, with red. Leaves from 1 in. to 1} in. long, often unequal at the base, densely downy on both surfaces, and white beneath. Catkins from 1 in. to 1} in. long.” (Forbes.) Smith has incidentally noted in Eng.

Frequent in the woods and on the mountains of Lapland. (Lin. and Smith.) A slender shrub, not unfrequently arborescent. Young branches clothed with long silky down. Leaves rather more than 2 in. long, and fin. wide. It is remarkable that, contrary to the nature of most Willows, the lower blunter leaves of each branch are furnished witi minute distant teeth ; while the upper and pointed ones are quite entire. Except in the teeth of the leaves, it comes nearer to s. Lapponum than any other. (Smith.) Introduced in 1818.

A native of the Highland mountains, especially those of Breadalbane and Clova; flowering there in June, but, in the willow garden at Woburn Abbey, in May. A larger and stouter shrub than S.glauca, of which it was supposed by the original finder to be the female plant; but barren as well as fertile individuals, of both species, agreeing exactly together in other respects, and differing alike from correlative ones of the other species, are now well known. In size and general habit, this most resembles S. glauca; but their discriminative marks are clearly discernible. The leaves of S. arenària are rather smaller and shorter, more precisely ovate, with a little sharp point; their upper surface dark green, reticulated with sunk veins, and clothed with thin cottony down, more dense and soft upon the young ones; the under side pure white, with dense cottony wool; the veins prominent; midrib reddish; the young leaves, as well as the floral ones, beautifully silky beneath. (Id.) Mr. Forbes states that he has plants of this willow with leaves not above half the size of those of others, owing to their being planted in a different soil; which will show, he says, “ how much culture

improves the size of these species of plants." ? Variety. - S. a. ? leucophýlla ; S. leucophylla Schleicher. (Borrer in a letter.) –
