ARBORETUM ANU FRUTICETUM.

PART III.

Spec. Char., Sec. Leaves broadly lanceolate, and pointed, with glandular ser-ratures, smooth, glaucous beneath. Catkins appearing before the leaves.Ovary sessile, ovate, smooth. Style elongated. (Sal. Wob., p. 51.) Anative of Switzerland and the south of France; flowering at Woburn inFebruary. Introduced in 1820. It is a rapid-growing tree, with darkgreyish branches, slightly covered with a powder, or bloom, similar to thatof S. acutifolia; the branches ascending obliquely. The tree at Woburn,though only four years planted, was, in 1830, nearly 25 ft. high. Thecatkins appear often in February, from large crimson buds, which dis-tinguish this species from every other, and make it very ornamental.There are plants in |the arboretum of Messrs. Loddiges, and at Flitwick,and Henfield.

Variation. The buds containing catkins are very large in the autumn; and, inthis state, it is the S. prafcox gemmata Ser. Sal. exsicc,, No. 83. (KochComm., p. 23.)

S 9. S. pomera'nica Willi!. The Pomeranian Willow.

Identification. Willd. Enum. Suppl., 66.; Forbes in Sal. Wob., No. 153.

Synonymes. S. rfaphnoldes Villars var., with narrower leaves, and more slender catkins. {KochComm., p. 23.) Mr. Borrer, in his manuscript list of grouped species, has indicated it as beingprobably a variety of 5. daphnoides.

The Sexes. The female is described in Sal. Wob.

Spec. Char., §c. Leaves lanceolate, tapering at both extremities, serrated;smooth and shining above, glaucous underneath. Stipules ovate, serrated ;their margins generally revolute. Catkins about 1 in. long. Ovaryovate, smooth. Style longer than the parted stigmas. (Sal. Wob., p. 281.)A native, of Pomerania. Introduced in 1822, and flowering, in the Woburnsalictum, in February and March. This is a rapid-growing kind, much re-sembling, in the colour of its branches and its mode of growth, S. prae' cox.The branches are long, smooth, round, shining, and copiously covered withsmall yellow dots: the preceding year’s shoots are covered with a violet-coloured powder, similar to that on the shoots of S. prte'cox, and S. acutifolia.The leaves are about 4 in. long, and nearly 1 in. broad, tapering towardsboth extremities, serrated; the serratures somewhat glandular, smooth, andshining on their upper surface, and glaucous underneath. Footstalks nearly1 in. long, purplish and villous on their upper side. Catkins appearing be-fore the leaves, and about 1 in. long. There are plants in the GoldworthArboretum, at Woburn Abbey, Henfield, and Flitwick.

Group iii. Triandrec Borrer. (Syn. Amygdalinae Koch.)

Osier Willows, with three Stamens in a Flower.

Stamens 3. Leaves lanceolate, approaching to ovate, serrated, glabrous,having large, rounded, toothed, more or less deciduous, stipules. Flowersloosely disposed in the catkin. Pistil stalked. Ovary mostly glabrous.Most of the kinds constitute excellent osiers, and become trees if left tothemselves. (Hook. Sr. FI., 2d ed., with adaptation.) The kinds may bedenominated, generally, the osiers with 3 stamens in a flower. Most, or all,when in the state of larger shrubs and trees, have their older bark ex-foliated in broad patches, in the manner of that of the western and easternplane trees (Platanus occidentalis L., and P. orientalis L.). Most or allare ornamental as shrubs, for their lanceolate, glossy, serrated leaves, andtheir flowers.
