The Sexes. The female is described and figured in Eng. Bot. Suppl. The male plant is not known.

Engraving. Eng. Bot. Suppl., t 2749.

Spec. Char., $$c. Upright. Young shoots slightly pubescent. Leaves gla-brous, flat, broadly obovate, narrower to the base, slightly toothed, glau-cescent beneath ; upper leaves acute. Stipules small, concave Flowersloosely disposed in the catkin. Ovary stalked, bluntish, glabrous in thelower part. Style as long as the linear divided stigmas. ( Borrer in E. B,Suppl.) Wild at Killin, in Breadalbane, where it was observed in 1810.Mr. G. Anderson had previously distinguished it, and communicated toMr. Borrer the plant from which the specimens figured were taken, butwithout informing Mr. Borrer in what part of Britain he had found thekind. That plant has formed a tree-like shrub, more than 12 ft. high, withcrooked, divaricated branches, and flowers in April. The twigs are shin-ing, greenish grey or slightly tinged with brown; at first, sparingly andinconspicuously pubescent. Leaves 1 in. to !■§ in. long; bright green and shin-ing above, more or less glaucous beneath. Catkin about 1 in. long whenthe flowers are in blossom, which are loosely set in the catkin. It flowers'in April. It resembles S. /aurina in the figure of the leaves; but that kinddiffers in its more acutely angled ramification; its mahogany-colouredtwigs, densely cottony while young; the abundance of short appressedhairs present on both surfaces of the young leaves; the more awl-shapedovary, white all over with cottony hairs; and the shorter style, with shortstigmas, the segments of which usually adhere together.

Branches at first erect, or wand-like,round, of a mahogany-colour, beset with copiousnearly upright leaves, and attaining, the height of 1338

6 ft. Catkins earlier than the foliage. If neglected, the plant becomes asmall tree. (Smith.) The twigs are very brittle, and unfit for any usefulpurpose. (Forbes.) There are plants at Woburn and Henfield; also in theGoldworth and Hackney arboretums.
