In the salictum at Woburn, it is a lowgrowing shrub, with slender, roundish, smooth, yellowish branches, rising about 3 ft. or 4 ft. high; flowering in May and June. “This species," Pursh observes, “ so frequently found in gardens under the name of S. tristis, is very far from being in any way related to it. The specimen in the
Banksian herbarium was collected by Houston, and, as it is said, in Vera Cruz; but I am confident that it is a more northern plant, as I have frequently seen it in Virginia.” (Fl. Amer. Sept., ii. p. 614.) There are plants in the Goldworth Arboretum, and at Woburn Abbey, Henfield, and Flitwick House ; also in the arboretum at Hackney, under the name of S. tristis.

A native of Scotland, in Anguss hire and other places; forming a bushy tree, with slender, spreading, flexible, smooth, purplish, or dark brown branches ; flowering in April. It is easily known from every other species, by its short obtuse catkins, and long dark leaves. After gathering, the young leaves especially exhale a strong scent, like the flavour of bitter almonds, but less agreeable. No use has been made of this willow, though it seems to abound in tannin.” (Smith in Eng. Fl.) from Scotland by the late Mr. Dickson. In Possil Marsh, 1319 on the north side of the canal; Mr. David Don. Marshes in Angusshire ; Mr. George Don. (Hooker.) Mr. Pursh has suspected it not to be

1321 and Mr. Borrer, or Sir W.J. Hooker, or both, have regarded it as probably the same as the S. angustifolia Wulfen. As to its relation to S. rosmarinifolia, Sir W. J. Hooker says, “I agree with Mr. Borrer in thinking that they are distinct, though the difference lies almost entirely in their ovaries: these are shorter in S. angustifolia, with denser, less glossy, and less truly silky hairs, with ovate and quite entire stigmas, and more shaggy bracteas.
