in the willow garden at Woburn Abbey, in April and May. This speciesgrows 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 1 in. to If in. broad ;densely silky on both sides, elliptic-lanceolate, with acute oblique points; thelower rather obtuse; margins entire; whitish and glaucous beneath; closelycovered with long, compressed, silky hairs. Midrib prominent, yellow.Footstalks yellow, pubescent, very stout, and much dilated at the base.Catkins 1 in. or more in length, appearing before the expansion of theleaves. They remain on the plant during the greater part of the summer ;by which peculiarity this very distinct species is readily known from everyother. The female plant is figured and described in the Salictum Woburnensc.

Spec. Char., S(c. Leaves lanceolate, very entire, bluntish ; hoary above, woollybeneath. Seed-vessels woolly and oblong. ( Forbes S. IV.) A native ofLapland; flowering there in May and June, and, in the Woburn collection,in April. Introduced in 1812. “ This appears to be a verydistinct species from glauca, claeagnifolia, arenaria, lanata, andStuartidna. It grows with me to about 1 ft. high, with short,pale, decumbent branches; sometimes the young twigs aretinged, with red. Leaves from 1 in. to 1f in. long, often un- .equal at the base, densely downy on both surfaces, and whitebeneath. Catkins from 1 in. to If in. long.” (Forbes.) Smithhas incidentally noted in Eng. FI., iv. p. 202., the followingcharacters of S. Lapponum L.: —“ Leaves 2 in. to 2f in. long,greyish, all over very silky, both sides alike at every period of their growth,and never cottony. Catkins large, with large floral leaves, like the properleaves. Bracteas oblong, hairy. Ovary and capsule sessile, peculiarlywoolly.” It grows wild in the alps of Lapland, everywhere. (Willd.)

Identification. Willd. Sp. PI., 4. p. 705.; Smith in Rees’s Cyclo., No. 131.

Spec. Char., fyc. Leaves oblong-lanceolate, wedge-shaped at the base, finely villous on both surfaces,glaucous on the under one; the upper leaves acute and entire; the lower bluntish and distantlytoothed. Frequent in the woods and on the mountains of Lapland. {Lin. and Smith.) A slendershrub, not unfrequently arborescent. Young branches clothed with long silky down. Leavesrather more than 2 in. long, and f in. wide. It is remarkable that, contrary to the nature of mostwillows, the lower blunter leaves of each branch are furnished with minute distant teeth ; whilethe upper and pointed ones are quite entire. Except in the teeth of the leaves, it comes nearerto S. Lappbnum than any other. {Smith.) Introduced in 1818.

A native of the Highland mountains, especiallythose of Breadalbane and Clova; flowering there in June, but, in the willowgarden at Woburn Abbey, in May.
