Spec. Char., §c. This has, like S. ^etulifolia, short catkins, and ^

distinctly serrated leaves ; but these are more acute, and of an «

ovate-lanceolate figure; and fhe long stylfe seems to afford a dis-tinctive character. ( Borrer in Eng. Sot. Suppl., t. 2753., in the lifetext.) It occurs on various Scottish mountains. {Id.') Wahlenbergcompares the stems and leaves to those of J?etula nana, from the jjjilglossy greenness of the latter, their prominent veins, and theirremaining on the shoots in a withered state till the following year,

The whole plant is very dark, and almost black when dry. {Hook. 1341Br. FI.)

Spec. Char., fyc. It differs from S. procumbens by its smaller, rounder, moreconspicuously serrated leaves; shorter, almost ovate, catkins; shorter,more truncate, and paler bracteas (scales); andmore distinctly quadrangularovary. From the remarkable pnmd facie resemblance of its leavesto those of .Betula nana, Mr. Forster has suggested for it thename of 5etulifolia. {Borrer in Eng. Bot, Suppl.) Mr. Borrer regards it as not certain that this kind is a native of Britain ; andthe question resting on whether the kind found by Dr. Stuart Inthe mountains of Glencoe is identical with S. Ilfyrsinites of Eng.

Bot,, or with S. procumbens Eng. Bot, Suppl., he has stated 1343that, to ascertain this, it would be necessary to inspect the specimens ofthe kind found by Stuart, preserved in Lightfoot’s herbarium. If the kindprove not British, Mr. Borrer does not know its source. Cultivated inthe willow garden at Woburn Abbey , it has flowered in May, and again inAugust. A sturdy, upright, bushy shrifb, 1 ft. to 2 ft. high, with abun-dance of short, leafy, dark purplish branches, hairy when young, not downy.Leaves very different from those of all the foregoing species, except S.malifdlia, in their rigid, thin, crackling, veiny texture; without anythingglaucous or cottony about them, the fine hairs on the younger ones beingscattered and silky. {Smith Eng. FI.) Pursh has included in his Fhr.Amer. Sept., ii. p. 617., a North American kind of willow, named S. Mjt-sinites : ? is this the same as either of the above.
